Slaughter sewage treatment equipment production base with first-class quality

Since the slaughtering
) sewage
contains a certain amount of large floating objects (blood, fur, debris, etc.), it is first intercepted with a grille to ensure the normal operation of subsequent equipment, because Slaughter sewage contains macromolecular organic matter such as blood, grease, etc., which will be difficult to degrade if it enters the aerobic environment directly, so the water effluent from the grille enters the septic tank. The existing septic tank in the slaughterhouse can achieve a certain treatment effect, but the concentration of the existing effluent is still very high and contains some grease. In order to reduce the load on the subsequent treatment facilities, it is considered to add a grease trap at the front end to remove grease. Due to working hours, the drainage cycle of the slaughterhouse is different from other sewage discharge cycles. It is mainly discharged at night. Therefore, a larger regulating pool must be set up to adjust the water quality and quantity to ensure the normal operation of the entire facility and reduce the subsequent impact on the slaughterhouse. The impact load brought by the facility,
) sewage
is collected in the regulating tank and then pumped into the subsequent treatment facility through a pump. After the sewage is treated in the front-end septic tank,
) the sewage
still contains most of the macromolecular organic pollutants, so it needs to be further degraded into small molecule substances to prepare for subsequent aerobic biochemistry, and Considering that the ammonia nitrogen and total phosphorus in the sewage exceed the standard, it is necessary to install an aerobic and anoxic alternating operating environment to achieve the alternating operation of nitrification and denitrification to achieve the effect of nitrogen and phosphorus removal. Here, the subsequent aerobic and phosphorus removal will be achieved by setting up a hydrolysis acidification tank. This is achieved by returning part of the treated effluent to the hydrolysis and acidification tank. The sewage enters the aerobic pool after hydrolysis and acidification. The aerobic pool is divided into two sections. The advantage is that in different aerobic sections, microorganisms present spatial distribution according to different environments, which is targeted and has better removal effect. After the sewage is treated by various front-end biochemical treatment facilities, the organic pollution load is degraded to a large extent. However, the chroma in the sewage is still difficult to reach the standard. In order to remove the chroma and simultaneously consider the reduction of ammonia nitrogen and total phosphorus, a coagulation sedimentation tank is set up here and targeted chemicals are added. The water from the sedimentation tank enters the disinfection tank and is finally discharged to meet the standards.
