内电解还原-高效厌氧反应工艺处理化工生产废水

TREATMENT OF WASTEWATER FROM A CHEMICAL PLANT BY INTERNAL ELECTROLYTIC REDUCTION-HIGH EFFICIENCY ANAEROBIC PROCESS

化工生产废水中有机物浓度高,成分复杂,采用常规的处理工艺难以达标。本工艺采用分级处理的方法,先通过催化氧化、内电解铁屑还原反应装置,降低生产浓废水中的有机物含量,改善污水的可生化性;再采用高效厌氧反应器进一步处理废水,有机物去除率高,出水水质稳定,实现了达标排放。

The wastewater from a chemical production plant contaminated with high concentration of organic matter, whose composition is complex.It is difficult to meet the discharge standard using conventional treatment processes.Our process employed multistage treatment method is used.First catalytic oxidation and fine iron powder internal electrolytic reduction reactor are used to reduce the concentration of organic matter in the wastewater and increase biodegradability of the wastewater.Then the wastewater inside the high-performance anaerobic reactor is further treatd.This method provides high efficiency of organic matter removal.The quality of the treated water is stable and meets the wastewater discharge standard.
