Slaughter wastewater treatmentProduct features:
(1) Slaughter wastewater contains a large amount of floating debris (blood stains, fur, impurities, dyes, etc.), which can be intercepted by grilles to ensure the normal operation of subsequent equipment.

(2) Slaughter wastewater is rich in high molecular weight organic compounds such as blood stains and oils, which are difficult to degrade when directly treated with aerobic agents. Therefore, the effluent from the grate enters the septic tank.

(3) The existing septic tank in the slaughterhouse wastewater treatment equipment plant can achieve certain treatment effects, but its effluent concentration is still high and carries some oil, reducing the load on subsequent treatment facilities. An oil-water separation oil separation tank can be added at the front end to remove oil.

(4) Due to working hours, the drainage cycle of slaughterhouses is different from other wastewater discharge cycles, mainly concentrated at night. A large regulating tank must be set up to regulate the water quality and quantity to ensure the normal operation of the entire facility and reduce the impact load on subsequent facilities. Wastewater is collected by the regulating tank and pumped into the subsequent treatment facilities.

Slaughter wastewater treatment equipment process：

(1) Slaughter wastewater treatment equipment: After being treated by the front-end septic tank, the wastewater still contains most of the large molecular organic pollutants, which need to be further degraded into small molecular substances to prepare for subsequent aerobic biochemistry. Considering the excessive levels of ammonia nitrogen and total phosphorus in the wastewater, it is necessary to set up an aerobic anoxic alternating operation environment to achieve the effect of nitrification denitrification and phosphorus removal. Here, a hydrolysis acidification tank is set up to reflux the effluent from subsequent aerobic treatment to the hydrolysis acidification tank.

(2) After passing through the hydrolysis and acidification tank, the wastewater enters the aerobic tank, which is divided into two sections. The advantage of this is that in different aerobic sections, microorganisms show spatial distribution according to the environment, which is targeted and has better removal effects.

(3) After being treated by various biochemical treatment facilities in the front-end, the organic pollution load is greatly degraded. However, the chromaticity in the wastewater is still difficult to meet the standard. In order to remove chromaticity and consider reducing COD, ammonia nitrogen, and total phosphorus, a coagulation sedimentation tank can be set up and targeted chemicals can be added.
