Embodiment Construction

[0034] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0035] A method for treating sewage generated by harmless treatment of animal corpses, comprising the following steps:

[0036] After the sewage produced by the harmless treatment of animal corpses is collected through the pipeline, the hair in the water is first collected by the hair collector 24;

[0037] Then it enters the grid well 1, and flows into the regulating pool 3 after being intercepted by the fixed grid 2;

[0038] After that, the sewage is pumped into the air flotation machine 5 through the lifting pump 4 of the regulating tank for pretreatment;

[0039] The scum of the air flotation machine 5 is discharged into the sludge tank 18, and the clear water in the sludge tank 18 flows into the anoxic tank 6 top;

[0040] The sewage from the air flotation machine 5 enters the anoxic tank 6, flows through the anoxic suspension ball fille...

Abstract

The invention relates to a treatment method and equipment for sewage generated by harmless treatment of animal carcasses, and belongs to the technical field of industrial sewage treatment. According to the technical scheme, the equipment comprises pretreatment equipment, biochemical treatment equipment and disinfection equipment. After large-particle impurities in the sewage generated by harmlesstreatment of animal carcasses are removed by gratings, the sewage is pumped into a gas floating machine through an adjusting tank lifting pump in an adjusting tank, and pollutants such as most suspended solid (SS) and chemical oxygen demand (COD), a part of ammonia nitrogen, and the like in the sewage is removed by a gas floatation effect. An anoxic tank (6), a moving bed biofilm reactor (MBBR) tank (9) and a facultative membrane bioreactor (MBR) membrane tank (12) are combined for performing biochemical treatment; a sludge tank is used for residue discharging of the gas floating machine and asmall amount of sludge discharging of the facultative MBR membrane tank; and the disinfection equipment is ultraviolet disinfection equipment. According to the invention, the process of treating thesewage by a conventional process is greatly simplified, the occupied area is small, and the treatment cost of each ton of water is low.

Description

technical field [0001] The invention relates to a treatment method and equipment for sewage produced by harmless treatment of animal corpses, and belongs to the technical field of industrial sewage treatment. Background technique [0002] Animal carcasses, regardless of whether they died normally or died of epidemic diseases, often carry a variety of germs. If they are not handled or handled properly, the carcasses will quickly decompose and rot and emit odors, causing pathogenic microorganisms to pollute the air, water and soil, resulting in the spread of diseases and spread, seriously endangering the physical and mental health of the surrounding population. Therefore, for animals that die abnormally or whose cause of death is unknown, the carcasses must be treated harmlessly. At present, most of the treatment methods in China are mainly wet method, which is to put the carcasses of dead animals in the equipment, and completely kill the pathogens by passing high-temperature...
