Device for purification and elimination of peculiar smell in breeding wastewater and operation method thereof

Abstract

The invention relates to the technical field of treatment of breeding wastewater, in particular to a purification and elimination device for purification and elimination of peculiar smell in breedingwastewater and an operation method thereof. The device comprises a breeding wastewater pool, a biological deodorization box and a biological deodorant box, wherein a photolysis catalysis box is connected to one end, away from the breeding wastewater pool, of a water delivery pipe. According to the invention, breeding wastewater is pumped into the biological deodorization box, and the wastewater istreated through a biological deodorant in the biological deodorant box, so foul gases such as hydrogen sulfide and ammonia gas in the wastewater can be effectively removed, the deodorization rate andthe fly inhibition rate of the wastewater reach 85% or higher, the contents of COD and ammonia nitrogen in the wastewater are obviously reduced, the purification speed and capacity of the wastewaterare improved, no toxic or side effect is caused to human beings, animals and plants, and no pollution is generated to the environment; the biological deodorant can be sprayed into the biological deodorization box through arranged spray heads, so the biological deodorant makes full contact with breeding wastewater; and a reaction speed and a wastewater purification effect are improved through continuous stirring.

Description

technical field [0001] The invention relates to the technical field of aquaculture wastewater treatment, in particular to a device for purifying and eliminating peculiar smell in aquaculture wastewater and an operating method thereof. Background technique [0002] In recent years, my country's aquaculture industry has developed rapidly, and the establishment of large-scale aquaculture farms has become the development trend of today's aquaculture industry. Modern farms have strict sanitation requirements and often produce a large amount of flushing wastewater. Aquaculture wastewater is a high-concentration organic wastewater rich in a large number of pathogens. If it is directly discharged into the water body or stored in an inappropriate place, it will be washed into the water body by rainwater, which may cause serious deterioration of surface water or groundwater quality. Due to the strong leaching property of livestock and poultry excrement and urine, the leaching amount ...
