Purification device for treating poultry farming wastewater through solar bio-floating bed

Abstract

Disclosed is a purification device for treating poultry farming wastewater through a solar bio-floating bed. The device comprises a plate-shaped floating body, a plurality of container bodies and a tank arranged in the middle, wherein the plate-shaped floating body comprises an upper floating plate, a lower floating plate and an interlayer, the upper floating plate is provided with a plurality of planting holes, an aquatic plant is planted into each planting hole, the lower floating plate is provided with a plurality of sieve pores, the interlayer is used for root growth of the aquatic plants, an air pump is installed at the upper end of the middle of the upper floating plate, the lower portion of an air outlet of the air pump is communicated with an air conveying pipe extending downwards, the lower end of the air conveying pipe is communicated with a plurality of aeration pipes, and the aeration pipes are used for injecting air below the plate-shaped floating body; all the container bodies are installed at the lower end of the lower floating plate, the side wall of each container body is provided with a plurality of meshes, and each container body is filled with a nitrogen removal composite biomaterial; the middle of the tank is filled with an iron-charcoal microelectrolysis purification filler. The device is used for treating water eutrophication caused by the poultry farming wastewater, and poultry farming surrounding water environment optimization and resource utilization are achieved.

Description

technical field [0001] The invention relates to the field of ecological restoration and treatment of water bodies in poultry breeding industry, in particular to a solar biological floating bed treatment wastewater purification device for poultry breeding industry. Background technique [0002] In recent years, my country's large-scale poultry breeding industry has developed rapidly, and its scale has continued to expand. For a long time, poultry farming enterprises have only pursued economic benefits one-sidedly, with weak awareness of environmental protection and backward treatment methods for fecal sewage, resulting in a large amount of high-concentration organic sewage being discharged into rivers and lakes, resulting in continuous deterioration of water quality. Among them, high concentrations of nitrogen and phosphorus in sewage are The main cause of eutrophication in water bodies. Most of the farms did not consider poultry manure treatment in the early stage of farm c...

AI Technical Summary

Problems solved by technology

The existing biological floating bed technology mainly relies on the plants planted on the floating bed to absorb N, P and other compounds and organic matter. Due to the limitation of the season and the floating bed plants, it only uses the surface water body for the floating plant, and the purification effect of the plant on the water body is limited. Eutrophication with extremely low dissolved oxygen even causes poor growth in water bodies, difficult maintenance and high cost, and it is difficult to further improve its purification effect

At present, there is a lack of effective purification technology for the oxidation pond treatment of aquaculture water with high nitrogen, phosphorus and organic matter and low dissolved oxygen content in the water.
