Biological pollution control method for industrial aquaculture wastewater

Abstract

The invention discloses a biological pollution control method for industrial aquaculture wastewater, which comprises a tank body, wherein a microporous gas distribution disc is arranged at the bottom of an inner cavity of the tank body; a dispersion cone is arranged above the microporous gas distribution disc; a spray head is arranged near the top of the inner cavity of the tank body; a circulating pipe penetrates near the bottom of the tank body; the circulating pipe passes through a water pump and is then connected with a backflow pipe near the middle part of the tank body through a pipeline; the backflow pipe extends into the tank body and is open downward above the dispersion cone; a sensor module capable of detecting the water quality also penetrates in the tank body; a tail gas discharge port is also formed in the top of the tank body; and a water outlet pipe is arranged on the side surface of the tank body. The method disclosed by the invention has the advantages of novel structure, thorough elimination of biological pollution, high treatment speed, low using cost, good safety, low environmental stress, low ozone dosage and small residual amount of ozone.

Description

technical field [0001] The invention relates to a method for purifying intensive aquaculture wastewater, in particular to a method for preventing and controlling biological pollution of industrialized aquaculture wastewater. Background technique [0002] The core concept of the circulating water factory aquaculture system is based on seawater treatment and system control technology, to create a pure and stable water environment, to simulate the natural marine environment on which various seafood depends, so that it can be bred and grown in the most natural way. For example, such as the Chinese invention patent "A System for Ecological Treatment and Recycling of Industrialized Fish Farming Wastewater", patent number 200810008753.1. Oxygen supply devices, temperature control facilities, artificial wetlands and other circulating water treatment facilities and equipment; use open large-flow water supply channels and return channels instead of closed pipes. Use foam separation f...

Problems solved by technology

However, the existing technologies mostly use methods such as microbial purification and natural aeration, which are slow, affected by environmental factors such as temperature and light, and have poor tolerance to extreme conditions, and are relatively space-consuming and bulky, so there are many limiting factors. unfavorable promotion
