The present invention discloses the processing unit and its application method of a kind of black and odorous water, is made of following：（1）Coagulating sedimentation or air-flotation system；（2）Electrolysis system；（3）Sludge treating system.Black and odorous water is separated into one section, one section of water body with rubber dam, fetched water again with elevator pump from the downstream of black and odorous water, elevator pump water outlet is connected with the water inlet of coagulating sedimentation system or air-flotation system, the water inlet connection of the water outlet and electrolysis system of coagulating sedimentation system or air-flotation system, the water outlet of electrolysis system are discharged into black and odorous water recirculated upstream；The import connection of the mud discharging mouth and sludge treating system of coagulating sedimentation system or air-flotation system enters sludge dewatering equipment, and sludge is dehydrated into clod and pressing filtering liquid by the dewaterer of sludge treating system.SS, COD, BOD, ammonia nitrogen, total nitrogen, total phosphorus, colourity are removed by coagulation, electrolysis, improve dissolved oxygen depth so as to administer black and odorous water. |
