Outline
The pure water generally prepared with industrial raw water by adopting the process of membrane treatment+mixed bed water treatment is used for boiler feedwater of coke dry quenching in coking industry. There is repeatability for membrane treatment process in advanced treatment of phenol cyanogen wastewater and preparation process of boiler feedwater, so demineralized water can be replaced by advanced treatment for contributing water to reduce the operating costs of enterprises. It is preliminarily determined to be with feasibility through studying the characters of water quality and water quantity of effluent from demineralized water system of boiler feedwater and reuse water of phenol cyanogen wastewater. The industrial test results showed that the indexes of effluent could satisfy the operating requirements of boiler for coke dry quenching, quantity of fresh water used was reduced by 90% and disposing costs of demineralized water was reduced by 15%~20% with the scheme, which could provide the technical support for “zero discharge” of phenol cyanogen wastewater.
