Bank-based detachable purification treatment device for bottom layer culture wastewater of pond

Abstract

The invention discloses a detachable culture pond sewage treatment system which comprises a cuboid container, the cuboid container is formed by wrapping a cuboid stainless steel support with high-density canvas, the cuboid container is divided into a left cabin body, a middle cabin body and a right cabin body which communicate with one another by a left partition plate and a right partition plate, a water inlet pipe led out from the bottom of a pond is connected to a sewage inlet pipe, the sewage inlet pipe is designed into a square flow dividing pipe, a filter bag is arranged on the square flow dividing pipe, an oyster shell layer is arranged at the bottom of the left cabin body, the bottom of the right partition plate is flush with the bottom side surface of the cuboid container, a channel is reserved between the top of the right partition plate and the top side surface of the cuboid container, a gravel layer and a ceramic ring layer are arranged in the middle cabin body between the left partition plate and the right partition plate, a biochemical cotton layer is arranged in the right cabin body between the right partition plate and the high-density canvas on the right side surface of the cuboid container, and the right cabin body is connected with a water outlet pipe. The detachable culture pond sewage treatment system can effectively remove residual feed and excrement in water of a sewage discharge system to purify the water, and the purified water can directly flow back to a culture pond or a wetland purification system.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an easy-to-install and detachable sewage purification treatment device for pond cultivation. Background technique [0002] Among the many aquaculture methods in China, pond aquaculture is still the most important method. According to statistics, the area of ​​freshwater pond aquaculture in my country has reached 2.7 million hectares in 2015, accounting for 43.94% of the total area of ​​freshwater aquaculture. Both production values ​​have made an important contribution to aquaculture. As the country requires to accelerate the construction of the spatial pattern, industrial structure and production mode of the green development of aquaculture, transform the breeding mode and improve the breeding environment, the problems exposed by the traditional pond farming method are becoming more and more serious. For example, problems such as frequent occurrence of diseases, environmental pollutio...

AI Technical Summary

Problems solved by technology

Relying solely on the self-purification ability of the water body cannot meet the actual production needs

Residual bait feces in the water body will lead to excessive growth of algae and deteriorate the water quality

At the same time, it will also cause a large number of harmful bacteria in the water to breed, threatening the health of fish and directly affecting the breeding efficiency.
