Ectopic gas stripping type circulating water purification culture system applying electric flocculation technology

Abstract

The invention discloses an ectopic gas stripping type circulating water purification culture system applying an electric flocculation technology. The ectopic gas stripping type circulating water purification culture system comprises a culture pond, an electric flocculation device, a water purification and sewage collection device, a gas stripping device and an intelligent display control device. The electric flocculation device is connected with a water outlet of the culture pond, the water purification and sewage collection device comprises a lower sewage collection chamber, an upper biological filtration chamber and a micro-filter screen arranged in the middle, the side wall of the sewage collection chamber is connected with the electric flocculation device, and the bottom of the sewage collection chamber is provided with a sewage discharge pipe and a sewage discharge control valve; the gas stripping device comprises a U-shaped gas stripping pipe connected with the upper part of the biological filtration chamber, a gas stripping water pipe arranged at the upper part of the gas stripping pipe, and an aeration head connected with an air pump and then arranged at the bottom of the gas stripping pipe; and the intelligent display control device is respectively connected with the online turbidity detector, the flow valve, a power supply of the electric flocculation device and the running water control valve. According to the invention, fine suspended particulate matters in the aquaculture water can be condensed into floccules with larger volume, so that the particulate matter pollutant collection and removal effect of the system is enhanced, and the low-cost, low-consumption and high-efficiency circulating water and water purification and pollutant collection effects can be realized.

Description

technical field [0001] The invention relates to the technical field of circulating water aquaculture and purification, in particular to an ectopic air-lift circulating water purification and aquaculture system applying electro-flocculation technology. Background technique [0002] Recirculating aquaculture has become one of the main models in the current aquaculture industry, and has significant advantages in saving water resources, reducing water pollution, and improving aquaculture efficiency. By integrating technologies such as environmental monitoring, water purification, and intelligent control, the recirculating aquaculture system can adjust the breeding environment, control the content of water pollutants, and better ensure aquaculture output and aquatic product quality. Among them, the aquaculture water purification technology is the core part of the recirculating aquaculture system. After the aquaculture wastewater is purified by sedimentation, filtration, steriliza...

AI Technical Summary

Problems solved by technology

Suspended particulate matter in aquaculture water presents the characteristic that the number distribution is concentrated in the small particle size range. After passing through the most commonly used filter screen (200 mesh), more than 50% of the suspended particulate matter will remain in the water body. Increase the filter mesh size. Reducing the diameter of filter holes can improve the removal rate of suspended particles, but it will bring about problems such as increased cost and easier blockage of the filter screen.
