Embodiment Construction
[0021] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0022] See figure 1 , is a process roadmap of the present invention, and a kind of coking wastewater optimization treatment process of the present invention comprises the following steps:
[0023] 1) Coking wastewater from coking, gas purification, and chemical product refining processes. After ammonia distillation, the ammonia nitrogen is reduced to 200-500mg / L; first stay in the grease trap for 1.5 to 2 hours to remove the light oil and heavy oil in the coking wastewater, and then reduce the ammonia nitrogen in the coking wastewater through air flotation treatment. The water quality of coking wastewater after air flotation treatment is: COD<4000mg / L, ammonia nitrogen<300mg / L, oil<30mg / L, SS<10mg / L, phenol<100mg / L, cyanide<20mg / L;
[0024] 2) Put the coking wastewater treated by oil separation and air flotation into the regulating tank and mix ...
