In this study, the pollution of direct and leakage in Shiwuli River was analyzed by combining anionic surfactant sodium dodecyl benzene sulfonate (SDBS) and dissolved organic matter (DOM) traceability methods, and the correlation and difference of each index were studied by Pearson correlation analysis method. The results showed that the content of SDBS in untreated domestic sewage was high (522~668µg/L), which was easily affected by industrial washing wastewater when characterizing the pollution situation. DOM is characterized by high percentage of CHOS compounds (83%~84%), protein + lipid components (80%~81%), high hydrogen-carbon ratio (H/C=1.6) and low-carbon nominal oxidation state (NOSC=-1) in untreated domestic sewage. Combining the advantages of SDBS and DOM traceability can effectively eliminate interference factors and make the characterization of river domestic sewage pollution more reliable. This study can provide new ideas and technical support for the analysis and traceability of the direct and leakage of domestic sewage pollution in rivers.

结合阴离子表面活性剂十二烷基苯磺酸钠(SDBS)与溶解性有机物(DOM)溯源手段对十五里河直排漏排污染情况进行分析,利用皮尔逊相关性分析方法研究各指标的关联.结果表明,SDBS在未经处理的生活污水中含量高(522~668µg/L),表征污染时指示作用较明确,但易受工业洗涤废水影响;DOM在未经处理的生活污水呈现高百分比CHOS化合物(83%~84%)与蛋白质+脂质组分(80%~81%)、高氢碳比(H/C=1.6)、低碳的标称氧化态(NOSC=-1)等特征,用以上指标评价污染更为全面,但易受污水处理厂尾水影响.结合SDBS与DOM溯源优势,可有效排除干扰因素,使污染情况表征更加可靠.本研究可为河流中生活污水直排漏排污染分析及其溯源提供新思路与技术支持.

结合阴离子表面活性剂十二烷基苯磺酸钠(SDBS)与溶解性有机物(DOM)溯源手段对十五里河直排漏排污染情况进行分析,利用皮尔逊相关性分析方法研究各指标的关联.结果表明,SDBS在未经处理的生活污水中含量高(522~668µg/L),表征污染时指示作用较明确,但易受工业洗涤废水影响;DOM在未经处理的生活污水呈现高百分比CHOS化合物(83%~84%)与蛋白质+脂质组分(80%~81%)、高氢碳比(H/C=1.6)、低碳的标称氧化态(NOSC=-1)等特征,用以上指标评价污染更为全面,但易受污水处理厂尾水影响.结合SDBS与DOM溯源优势,可有效排除干扰因素,使污染情况表征更加可靠.本研究可为河流中生活污水直排漏排污染分析及其溯源提供新思路与技术支持.

In this study, the pollution of direct and leakage in Shiwuli River was analyzed by combining anionic surfactant sodium dodecyl benzene sulfonate (SDBS) and dissolved organic matter (DOM) traceability methods, and the correlation and difference of each index were studied by Pearson correlation analysis method. The results showed that the content of SDBS in untreated domestic sewage was high (522~668µg/L), which was easily affected by industrial washing wastewater when characterizing the pollution situation. DOM is characterized by high percentage of CHOS compounds (83%~84%), protein + lipid components (80%~81%), high hydrogen-carbon ratio (H/C=1.6) and low-carbon nominal oxidation state (NOSC=-1) in untreated domestic sewage. Combining the advantages of SDBS and DOM traceability can effectively eliminate interference factors and make the characterization of river domestic sewage pollution more reliable. This study can provide new ideas and technical support for the analysis and traceability of the direct and leakage of domestic sewage pollution in rivers.

生活污水是城市河流的潜在污染源之一,易对河流生态系统造成长期损害[1].未经处理的生活污水直接排放会对水体环境和周边居民身心健康造成严重影响[2].研究生活污水污染下河流的水质特征,有助于了解河流沿程受生活污水污染情况、确定污染位置,对生态环境部门指导相关区域整改完善,杜绝由生活污水直排漏排带来的水污染具有重要意义.
溯源河流生活污水污染的研究目前主要聚焦于某些指示物,如利用直链烷基苯做污水分子标识物评估河流污染情况[3],利用人类粪便特征指示基因HF183来评价河流受人类粪便污染情况进而评价生活污水污染[4];或利用同位素方法,如通过氮氧双同位素分析水体硝酸盐来源,进而推测生活污水对水体污染程度高低[5];或是利用溶解性有机物(DOM)的示踪效果,根据水体中DOM的变化推断生活污水对水体污染程度[6]等.以上方式各有相应效力,但单一判别方式可能受其他环境因素影响.近年来,多种评价方法被结合用于研究河流中某些污染物之间的关联,全面解析河流污染情况,如结合利用化学追踪与粪便污染标记物方法,发现个人护理产品、咖啡因与人类粪便指示物大肠杆菌、病原体呈现相关性[7]等.
据统计,中国表面活性剂的产销量居世界第一,直链烷基苯磺酸钠(LAS)是主要的阴离子表面活性剂之一,占销售量近一半,是洗衣领域中最常用的表面活性剂[8].先前研究在未经处理的生活污水、天然水体中均检测到LAS[9-10],未经处理的生活污水中LAS的浓度通常为1000~10000µg/L,远高于地表水.中国地表水中LAS的浓度范围为17~1200µg/L,与其他国家相比具有更高水平[11].污水处理厂对于LAS的去除率高,经污水厂处理后的LAS含量极低,LAS中十二烷基苯磺酸钠(SDBS)检出频率较高,地表水中LAS含量常用SDBS的浓度表示[12].
DOM作为水生态系统中的主要有机碳,参与了全球碳循环、营养盐和污染物迁移等多种地理生物化学过程[13].河流DOM的分子组成易受人类活动影响,具有明显的空间变异性[14-15],DOM的组成和特征为地理生物化学过程提供重要信息,进行相关研究对于了解其来源、环境影响具有重要意义.
十五里河是中国巢湖流域一条典型的城市小流域雨源性河流,周边城镇居民数量多,易受人类生活影响.本研究以十五里河为研究对象,利用SDBS和DOM溯源方法探究十五里河受生活污水直排漏排影响下水质参数空间变化及其关联,对十五里河沿程是否存在生活污水直排漏排情况进行综合判断,并通过实地考察调研对判断结果进行确认,最终对方法可行性进行评价.
十五里河(117°14′E~117°22′E,31°43′N~31°49′N)是合肥市西南部的重要洪水通道[16],流域面积约106.6km2,全长约22.9km,平均坡降为0.5‰.年平均流量约为1.19m3/s,城市径流量约占60%.来自污水处理厂的尾水约占40%[17].
样品采集时间为2023年12月(枯水期),河流处于多日未降雨(>5d)后相对稳定的时期.沿十五里河采集了17个水样,具体位置见图1,样品储存在聚乙烯采样瓶中,避光保存于冷藏箱内,并在6h内运输至实验室.将1L样品通过0.45µm微孔滤膜过滤,并将滤液用盐酸酸化至pH=2[18],在进一步分析前储存在4℃的黑暗环境中.
化学需氧量(COD)和营养盐类(、TP)采用标准方法测定[19];氢离子浓度指数(pH)、溶解性有机碳(DOC)、溶解氧(DO)、电导率(EC)采用相关仪器直接测定;大肠杆菌取未经过滤的原水于麦康凯琼脂培养基[20],36℃恒温培养36h进行测定.
采用固相萃取法富集水中SDBS和DOM[21],用于后续检测.为活化萃取柱并洗去杂质,依次用20mL甲醇和20mL酸化超纯水(pH=2)淋洗PPL柱(500mg,6mL,Agilent公司);再将500mL处理过的水样以5mL/min的速度通过PPL柱;样品全部通过后,用20mL酸化水淋洗小柱以去除残留盐分,随后用氮气吹干PPL柱并用甲醇洗脱,洗脱液定容至10mL,在-20℃避光保存.
取固相萃取洗脱液一份(10mL),用氮气吹干洗脱液,加超纯水溶解至1mL,置于棕色液相小瓶中,于4℃避光保存,直至上机检测.
SDBS的测定采用高效液相色谱质谱法[22-24],相关条件如下,仪器型号:UHPLC-Orbitrap-MS(Thermo公司),色谱柱:HYPERSIL GOLD Vanqulsh(100mm×2.1mm,1.9um,Thermo公司).柱温:45℃,流速0.25mL/min,梯度洗脱过程以质量分数0.1%乙酸铵水溶液(A1)和乙腈(B2)为流动相:0~8min(90%A1,10%B2-10%A1,90%B2),8~8.1min(10%A1,90%B2-90%A1,10%B2),8.1~10min(90%A1,10%B2),进样量10µL.在负离子模式(ESI-)下进行测定,检测模式:Full Ms,喷雾电压3.0kV,鞘气:35arb,辅助气:10arb,分辨率:7×104,质荷比(m/z)收集范围:100~1500,样品加标回收率80.4%~89.5%(加标浓度0.5~5µg/L).
DOM测定采用超高分辨率质谱法,利用Orbitrap-MS(Eclipse型,Thermo公司)在ESI-模式测试DOM的分子组成.喷雾电压3.8kV,鞘气5arb,辅助气2arb,进样速度20µL/min,分辨率1×106m/z收集范围100~1000.数据处理使用XCalibur Qual Browser软件.扣除背景干扰后,筛选出信噪比(S/N)>5且相对丰度>1%的质谱峰.利用Matlab R2021b进行对应质谱峰的分子式筛选[25],分子式需满足以下条件:元素范围C0-50HO0-30N0-6S0-2P0-2,DBE≥0,H/C范围0.3~2.5,O/C范围0~1.2[26],符合氮规则,质量精度误差≤2×10-6[27].筛选结果代表DOM分子组成.
根据筛选出来的分子式,计算DOM的m/z、H/C、O/C、修正的芳香性指数AImod,不饱和度DBE,碳的标称氧化态NOSC等参数[28].
式中:C、H、O、N、S、P代表DOM元素组成中碳、氢、氧、氮、硫、磷原子的数目.
应用SPSS 20.0对十五里河河水样本中体现未经处理的生活污水特征的指标进行皮尔逊(Pearson)相关性分析,并利用Origin 2022绘制相关性热图.
水样基础水质指标变化情况如图2所示,与河流水质相比,未经处理的生活污水主要体现出低DO、低、高EC、高COD、高、高TP、高DOC、高大肠杆菌特征,污水厂出水水质与河流水质差异不大.
图2中虚线标注《地表水环境质量标准》(GB3838-2002)Ⅴ类水限值[29],本次检测,十五里河COD、和大肠杆菌浓度超过限值.上游DO平均浓度(9.41mg/L,S2~S4)高于中下游(7.32mg/L,S5~S12),COD变化趋势相反,上游平均浓度(16.49mg/L,S2~S4)低于中下游(50.33mg/L,S5~S12).在点位S6~S8出现了明显浓度下降与浓度上升,这可能是由于点位S6~S8处河道宽阔,水深较深,水体流动性差,DO不足,为的反硝化提供了适宜的环境,同时,在点位S10~S12处再次表现出相同的变化趋势,而点位S9出现的突然下降则可能与支流许小河汇入有关.
浓度(0.30~5.30mg/L,S2~S12),TP浓度(0.06~0.28mg/L,S2~S12),这两个指标具有相似的变化趋势;在点位S2、S3处虽含量较低,但均存在明显的上升趋势,在点位S7、S8、S9处的高值,可能是由于周边人为活动的影响,而在S11处表现出的与TP浓度上升,可能是承接了周边农村居民生活污水或农业、养殖业废水.
DO浓度(3.65~10:00mg/L,S2~S12),在点位S7、S8、S9处,河流水体DO呈现明显低值(3.65~6.04mg/L),这一方面可能是由于河道宽阔,水流缓慢导致大气复氧减少;另一方面可能存在人类生活影响,如工业废水或生活污水的污染.
大肠杆菌指标变化差异较大(3.3~215.3万个/L,S2~S12),点位S2与S3出现高大肠杆菌浓度,附近可能存在人类粪便污染或禽畜粪便污染.在点位S6与S11也存在大肠杆菌浓度高值,S6处可能存在生活污水污染,S11处可能存在周边农户生活污水排放、农业耕种施用粪肥或禽畜养殖等.
其他指标,如pH值、EC差异较小,并未体现明显的空间变化规律,根据分析,COD、DOC、并未体现明显的与生活污水直排漏排污染相关的变化,基础指标中,能体现直排漏排污染的相关指标为、TP、DO以及大肠杆菌.
由水质基础指标变化情况分析,点位S2、S3、S7、S8、S9、S11处有多个指标指向生活污水直排漏排特征,在这些点位附近可能存在相关污染.
LAS的平均链长为C11.6~C11.9[30],地表水中阴离子表面活性剂的富集程度常用C12LAS即SDBS表示[31].两个污水处理厂进水SDBS的浓度分别为688与522µg/L,而污水处理厂出水中SDBS浓度为1.22与1.98µg/L.
有研究发现,滇池LAS浓度最高达14450 µg/L,远高于其他水体,约为地表水Ⅲ类标准值(GB 3838-2002)[29]的70倍,这可能与未经处理的生活污水排入有关[31];另有研究认为,与高营养负荷相关的LAS污染主要是来自未经处理的生活污水[32];根据前人研究结果以及本研究对污水厂进出水SDBS浓度的测定情况,选取SDBS作为生活污水直排漏排污染的一个表征指标.
十五里河SDBS浓度变化如图3,在空间上变化明显,大部分点位浓度均大于污水厂出水(<2.00µg/L),说明水体存在生活污水直排漏排污染.在点位S2、S3,SDBS呈现高值(6.08~6.81µg/L),这两个点位周边多为居民住宅,可能存在着生活污水直排漏排污染;点位S4~S6,SDBS含量处于低水平(0.60~1.21µg/L);在点位S7,SDBS含量陡然升高,达到峰值(8.10µg/L),S7、S8上游不仅有居民区,还有一些工业企业,而工业企业的洗涤废水也具有很高的SDBS浓度,此处污染源可能有工业源和生活源;点位S9与S11处,SDBS含量呈现上升趋势,可能是由于支流汇入带来沿线洗涤废水,S9处汇入支流为许小河,沿线主要是城市居民生活区,S11处汇入支流为圩西河,沿线主要是农村区域,已有的研究表明农村生活源是地表水LAS污染的主要来源,占总LAS排放量的83%[31],S11处SDBS含量上升可能与周边农村生活污水排放有关.
由SDBS浓度变化分析,点位S2、S3、S7、S8、S9、S11处SDBS含量较高或呈现明显增加趋势,附近可能存在生活污水直排漏排.
从分子层面探索DOM特征,能够为DOM来源以及变化情况提供更为精确的信息.各水样DOM的分子总量特征见表1,与十五里河水相比,未经处理的生活污水具有高H/C、低AImod、低NOSC、低DBE/C的特点.
质荷比m/z用于说明DOM平均相对分子质量大小,m/z越大,DOM平均相对分子质量越大,十五里河m/z(282.6~322.0),珠江口m/z(387.7~417.6)[33],鄱阳湖m/z(380.45~386.79)[34],与其他天然水体相比,十五里河m/z相对较低,河流受人类生活影响较大.
H/C用于说明DOM生物利用性,值越低表示生物利用率越低,不利于水生物和微生物生长利用[35].碳的标称氧化态(NOSC)用于表示DOM的成熟度与稳定性,NOSC越大说明DOM越成熟,稳定性越强[36].点位S2、S3处H/C较高,生物可利用性较好,同时NOSC低,稳定性较差,这可能是由于周边人类生活的影响,存在直排漏排等;点位S9处H/C的较高值与NOSC的降低可能是由于支流许小河汇入,带来支流沿线直排漏排的生活污水;S11处相同的变化规律可能与点位附近农村居民生产生活有关.
AImod用于表示DOM芳香性,AImod低,芳香性低[37];DBE/C用于评价单位C原子的不饱和程度,DBE/C越低,表明单位C原子对应的不饱和程度越低[38];两个指标呈现相似的变化趋势;在中游呈现高值(0.29~0.32,S5~S8)、(0.51~0.56,S5~S8)而在上下游呈现低值(0.26~0.29,S~S4、S9~S12)、(045~0.51,S2~S4、S9~S12),河流中游DOM芳香性与单位碳原子不饱和程度高于上下游.
综上来看,用于表征生活污水直排漏排污染情况时,H/C与NOSC变化表明S2、S3、S9、S11处可能存在污染;其余分子总量特征适用于整体描述河流水质或更长河段水质的特征描述.
按照元素组成,各水样DOM可分为多种类型的化合物[26,28],并具有不同的相对丰度特征,结果如图4所示.
同十五里河水相比,污水厂进水DOM具有低CHO与高CHOS化合物比例.先前研究中,自然水体中CHO类化合物应占大部分,如鄱阳湖(66%~71%)[34]、长江(69%~74%)[39],而十五里河中优势化合物是CHOS,这与前人研究中城市河流DOM中CHOS化合物占比升高以至超过CHO化合物的情况相符[40]. DOM中杂原子(N、S、P)丰度大,这是因为十五里水源补充主要来自城市径流与污水厂尾水,易受到人类生活影响,CHOS组分可能来源于合成表面活性剂及相关衍生物,也可能来自化石燃料燃烧副产物的大气沉降[41].由图4可知,自点位S5开始,CHOS化合物占比维持较高水平,与污水厂尾水接近,符合实际情况.若CHO化合物比例下降,而杂原子化合物比例增加,可能是由于受人类活动影响,生活污水、农业废水等汇入河流[42].
在点位S2处存在低CHO与高CHOS化合物比例,可能与周边人为活动有关,如生活污水直排漏排;点位S5、S6、S8、S10处CHOS比例上升与CHO比例下降,可能是由于污水厂处理尾水的排入或生活污水污染;点位S7处CHO化合物比例下降,杂原子化合物比例升高,说明此处可能存在较强人为影响.
由H/C与O/C差异,DOM分子可被划分为蛋白质+脂质、木质素、单宁等物质,划分范围如下:木质素(H/C:0.7~1.5,O/C:0.1~0.67)、单宁(H/C:0.5~1.5,O/C:0.67~1.2)、碳水化合物(H/C:1.5~2.4,O/C:0.71~1.2)、蛋白质(H/C:1.5~2.2,O/C:0.1~0.52)、脂质(H/C:1.5~2.0,O/C:0~0.3)、氨基糖(H/C:1.5~2.2,O/C:0.52~0.71)、不饱和烃(H/C:0.7~1.5,O/C:0~0.1)、稠合芳香族化合物(H/C:0.2~0.7,O/C:0~0.67)[26],由于蛋白质和脂质区划存在交叉且来源相近,划分为一类.利用范氏(van Krevelen)图对DOM分子化合物组成进行可视化处理(图5),以分辨各点位分子化合物相应的元素组成;同时计算各类化合物相对丰度(图6).
结合图5图6可知,十五里河各点位(S2~S12)DOM中,单宁和木质素分子数目最多,且相对丰度最高(56%~86%),这与前人研究中自然水体DOM特征一致[39-40,43],木质素和单宁类化合物主要来自植物分解,性质稳定[43],若木质素与单宁占比降低,则说明其他DOM源贡献增加.由图5可直观地看出,河水样本各点位DOM中蛋白质+脂质和不饱和烃组分主要由CHOS化合物构成,二者可能CHOS化合物具有来源上的关联,具有对人为因素影响的指示作用,有研究表明,蛋白质+脂质的高丰度常由人类生活引起[44],同时,受人类生活影响严重的水体具有更高的不饱和键含量[45];生活污水、养殖废水等都可能是此类组分丰度增加的原因.
图6可知,与十五里河水相比,污水厂进水具有高比例蛋白质+脂质、不饱和烃以及低比例木质素与单宁成分;点位S2、S3体现该特征,可能存在生活污水直排漏排污染;自点位S7、S8呈现的木质素与单宁比例下降以及蛋白质+脂质比例上升趋势,可能是周边存在生活污水直排漏排污染;点位S9、S11处木质素与单宁比例下降与脂质+蛋白质比例上升,可能是支流汇入带来了大量易生物降解活性物质,这与支流周边居民生活有关.
以DOM分子元素组成中CHOS与CHO化合物比例变化推测,点位S2、S5、S6、S7、S8、S10附近可能存在未经处理的生活污水污染;而根据DOM分子化合物组成中蛋白质+脂质与不饱和烃以及木质素与单宁比例变化,点位S2、S3、S7、S8、S9、S10、S11附近可能存在生活污水直排漏排.
根据水样测试结果,不同指标指向的可能污染点位存在异同(表2).
根据表2,S2、S3、S5、S6、S7、S8、S9、S10、S11均为可能的污染点位;根据DOM超高分辨率质谱结果,点位S5、S6、S10并未得到全部指标指向,可能是由于相关点位受附近污水厂出水影响而非生活污水直排漏排;根据SDBS结果,对可疑点位S5、S6、S10进行排除,因为这3个点位并未体现高SDBS浓度或SDBS增加趋势;S7处SDBS浓度呈现峰值,而S7处DOM并没有明显的未经处理的生活污水污染特征,故此处SDBS贡献源可能不仅有生活污水直排漏排;经过实地调查发现点位S6~S7之间存在污废水排口,水面漂浮大量泡沫状物质,该处污废水排放应是导致S7处SDBS出现最高值的主要原因,而此处依然有生活污水漏排痕迹,如岸边雨水井在长期未下雨的情况下出现明显水流声,且相连雨水排口处有明显臭味;点位S2、S3附近是小区,不存在工业企业,故此处生活污水直排漏排应是可能的主要污染源;S7~S8之间部分河面上漂浮明显脏污,S8处水体的污染一方面来自上游来水,另外一方面也与此河段生活污水直排漏排有关;对于点位S9,支流许小河沿线主要是居民区以及商业区,多个雨水排口处发现明显脏污,可能存在直排漏排污染;而S11处除存在圩西河汇入外,附近还有一些鱼塘及水沟,水沟中漂浮生活垃圾,应与周边居民生活相关,养殖废水与周边村民生活均是导致此处污染的原因.根据实际情况来看,S2、S3、S7、S8、S9、S11处应存在生活污水直排漏排.
用于指示生活污水直排漏排情况时,各指标均有一定说明效力,但单独使用时又分别具有局限性,见表2各指标主要干扰因素.大肠杆菌浓度可能受养殖废水、禽畜粪便的影响,如点位S6与S11处呈现的高大肠杆菌现象,就可能存在禽畜养殖影响,同时也掩盖了其余点位的生活污水直排漏排判断,故造成点位S6的误判与S8、S9的遗漏;SDBS作为洗涤排水指示物也受到工业洗涤排水的影响,在工业上LAS也是一种常用的洗涤剂,工业废水中也含有较高的SDBS,故造成点位S7生活污水直排漏排情况误判;DOM质谱分析中污水厂尾水排入易造成河流整体CHOS比例升高,掩盖生活污水直排漏排造成的比例变化,造成S3、S9的遗漏;H/C与NOSC指标容易受工业废水排入影响而掩盖生活污水直排漏排特征,造成点位S8遗漏.
对十五里河水体几个主要的未经处理的生活污水特征指标进行相关性分析,结果见图7,这些指标并非总是呈现出高相关性,这是由于不同指标判断效果会受不同干扰因素影响,另一方面不同指标对未经处理的生活污水污染情况的响应程度不同.因此,若是要明确定性生活污水直排漏排情况,需要多个指标联合指示.
SDBS判断生活污水直排漏排情况时具有明确而直观的指示效果,但受到工业废水干扰时易掩盖生活污水直排漏排特征;与之不同,DOM虽存在判断效果模糊的缺陷,但胜在指标多元,同时其主要干扰因素是污水处理厂尾水,受工业洗涤尾水影响小;两方法联用可使生活污水直排漏排情况判断更为准确.
根据以上分析,结合表2,采样点位S2、S3、S7、S8、S9、S11处存在生活污水直排漏排,经过实地考察,各点位均存在生活污水直排漏排痕迹,与此判断结果一致,其中点位S2、S3、S7、S8、S9属于城市地区,污染主要来自雨污混接与直排漏排,点位S11属于农村地区,生活污水污染主要来自周边农村居民生活,综上所述,利用SDBS与DOM溯源方法可较为全面地指出存在生活污水直排漏排情况的区域.
3.1 本研究结合SDBS与DOM超高分辨质谱分析,对十五里河沿程是否存在生活污水直排漏排情况进行综合判断,各方法间既存在一致性又存在差异性,结合实地调查情况,点位S2、S3、S7、S8、S9、S11处存在相关污染.
3.2 以SDBS判断直排漏排情况,利用SDBS在未经处理的生活污水中含量高(522~668 µg/L)的特征,其结果指示作用较明确,能够定位可能的污染点位S2、S3、S7、S8、S9、S11;但容易受到工业废水影响,造成直排漏排污染程度判断过高,如点位S7.
3.3 以DOM判断直排漏排情况,主要利用DOM在未经处理的生活污水呈现高百分比CHOS化合物(83%~84%)与蛋白质+脂质组分(80%~81%)、高氢碳比(H/C=1.6)、低碳的标称氧化态(NOSC=-1)等特征,其指标多样,对污染评价更为全面,能够定位到可能的污染点位S2、S3、S5、S6、S7、S8、S9、S10、S11;但部分指标容易受到污水处理厂尾水影响,呈现与未经处理的生活污水污染相似的表现,造成误判,如点位S5、S6、S10.
3.4 依据SDBS与DOM结果的一致性相互印证,为河流生活污水直排漏排状况提供了有力证据.而不同指标的差异性又有助于更全面地评估污染水平,减少单一方法受多种因素影响而产生的潜在偏差.总体而言,联合SDBS与DOM指标的生活污水直排漏排情况判断增强了评估结果的置信程度.
