Abstract

The invention discloses a physicochemical removal system and method for nitrogen and phosphorus pollution factors in aquaculture wastewater, and the physicochemical removal system for the nitrogen and phosphorus pollution factors in the aquaculture wastewater comprises a PH regulating tank, a reaction tank, a sedimentation tank and a clear water PH natural callback tank which are sequentially communicated from left to right, an alkaline calcareous buffering agent adding device for adding an alkaline calcareous buffering agent into the PH adjusting tank is arranged on the left side of the PH adjusting tank, a gas collecting hood for collecting ammonia gas is arranged above the PH adjusting tank and the reaction tank, and the gas collecting hood covers the PH adjusting tank and the reaction tank; a first aeration device is arranged at the lower end in the PH regulating tank. Under the synergistic effect of a physical treatment method and a chemical treatment method, the ammonia nitrogen removal rate reaches 98.5%, the total phosphorus removal rate reaches 98.3%, the COD removal rate reaches 30%, the removal efficiency is high, meanwhile, secondary pollution caused by precipitates and generated ammonia gas is prevented, and the environmental and economic benefits are stable.

Description

technical field [0001] The invention relates to the technical field of physical and chemical treatment of sewage, in particular to a system and method for physicochemical removal of nitrogen and phosphorus pollution factors in aquaculture wastewater. Background technique [0002] With the rapid development of my country's economy, the problem of water pollution is becoming more and more serious, and the pollution of high ammonia nitrogen and high total phosphorus in aquaculture wastewater is more and more serious. Due to the strong leaching properties of livestock and poultry manure in breeding wastewater, especially the leaching amount of nitrogen and phosphorus in manure and urine is very large, if not properly treated, it will enter the groundwater layer through surface runoff and infiltration to pollute the groundwater. [0003] A large amount of suspended solids in aquaculture wastewater can make the water turbid, reduce the photosynthesis of algae in the water, and lim...
