Freshwater clam cultivation device for small watershed sewage government

Abstract

The invention discloses a freshwater clam cultivation device for small watershed sewage government, and belongs to the technical field of sewage government. The freshwater clam cultivation device forsmall watershed sewage government adopts the scheme that air is ventilated through an air duct, so that pressure intensity in a material storing tank is increased, a release ball moves upwards, nutrient materials on the surface are ejected out from the material storing tank, after being ejected out from the material storing box, the release ball is in contact with a T-shaped cylinder to rush intoa contact groove, the nutrients on the surface of the material storing box are absorbed by a sponge column and are spread to the entire sponge column, small watersheds absorb the nutrient materials through foraging holes during vital activity, through V-shaped grooves and microvillus, the nutrient materials can be absorbed, the microvillus can generate bubbles during air flowing, the nutrient materials can be convenient to peel off, and absorption by the small watersheds can be convenient. The purpose of reducing fecal pollution to a water body can be realized, so that a water body is not liable for eutrophication, the living environment of the small watersheds is increased, and the yield of the small watersheds is increased.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically relates to a freshwater mussel cultivation device for sewage treatment in small watersheds. Background technique [0002] Water mussels are river mussels, which are distributed in Asia, Europe, North America and North Africa. Most of them can naturally form pearl meat in their bodies and are edible. There are many kinds of shellfish that live in rivers, rivers, lakes, and swamps. The common species like to live In flowing rivers, another type likes to live in ponds with calm water surface (easy to parasitize leeches), a general name for shellfish of the genus Anodonta, a clam , distributed in Asia, Europe, North America and North Africa, common bivalves in freshwater lakes, rivers and ponds, living in bottom burial. [0003] Small watershed usually refers to a relatively independent and closed natural water catchment area below the secondary and tertiary tributarie...

AI Technical Summary

Problems solved by technology

[0004] At present, in the process of cultivating freshwater mussels, water tanks are usually used to concentrate the cultivation of mussels in batches in freshwater lakes, and by adding nutrients (mainly chicken manure, duck manure and other poultry manure) Feed mussels, but in the process of feeding nutrients, the poultry feces will pollute the water body, which will easily cause eutrophication in the water body, and then destroy the ecological environment of the entire lake
