Reclaimed water reuse treatment process

Abstract

The invention discloses a reclaimed water reuse treatment process adopting a process technical route composed of a sewage tank 1, a grating filter tank 2, a regulating tank 3, a flocculant dosing tank 4, a dosing metering pump 5, a primary sedimentation tank 6, an aeration tank 7, a final sedimentation tank 8, a multi-stage filter 9, a disinfectant tank 10, a disinfectant metering pump 11, a reclaimed water reservoir 12, a reclaimed water lifting pump 13, a Roots blower 14, an aeration disperser 15, an aeration conveying pipeline 16, a sand filter wall 17 and a PP cotton filter wall 18. Along with the rapid development of the breeding industry, more and more large-scale breeding farms appear, a large amount of concentrated breeding sewage is generated, the breeding sewage is recycled after being properly treated, and the water is used for the daily non-drinking water situation of the breeding farms, so that the pollution discharge amount of the breeding farms is reduced, and the water cost of the breeding farms is saved.

Description

technical field [0001] The invention relates to a treatment process for reclaimed water, specifically treating the sewage of livestock farms through a certain process to make it reach the standard of non-living drinking water in the farm, which belongs to the technology of livestock breeding sewage treatment and environmental protection equipment technology field. Background technique [0002] With the rapid development of the aquaculture industry, more and more large-scale farms have emerged, resulting in a large amount of concentrated aquaculture sewage; usually the aquaculture sewage mainly includes livestock and poultry urine, feces and flushing water for farms. This type of sewage organic matter , high concentration of ammonia nitrogen, phosphorus, and more suspended solids. These high-concentration organic sewage rich in a large number of pathogens are directly discharged into the water body or stored in an inappropriate place. If they are washed into the water body by ...

[0002] With the rapid development of the aquaculture industry, more and more large-scale farms have emerged, resulting in a large amount of concentrated aquaculture sewage; usually the aquaculture sewage mainly includes livestock and poultry urine, feces and flushing water for farms. This type of sewage organic matter , high concentration of ammonia nitrogen, phosphorus, and more suspended solids. These high-concentration organic sewage rich in a large number of pathogens are directly discharged into the water body or stored in an inappropriate place. If they are washed into the water body by rainwater, it may cause serious deterioration of surface water or groundwater quality. At the same time, some germs and viruses in the breeding sewage may cause the spread of certain epidemic diseases, etc., which will bring many safety problems and hidden dangers such as the quality and safety of animal husbandry products, ecological environment safety, human and animal health, etc. Besides, my country is another countries with water shortages
