A freshwater mussel culture device for sewage treatment in small watersheds

Abstract

The invention discloses a freshwater mussel culture device for treating sewage in small watersheds, belonging to the technical field of sewage treatment, and relates to a freshwater mussel culture device for treating sewage in small watersheds. In this solution, air is introduced through an air guide tube, so that the internal pressure of the storage box is increased. Larger, so that the release ball moves up, and the nutrient on its surface pops out of the storage box. After the release ball pops out of the storage box, it contacts the T-shaped cylinder and rushes into the contact groove. The sponge column removes the nutrients on the surface of the storage box. Nutrients are absorbed and diffused to the entire sponge column. During life activities, mussels absorb nutrients through foraging holes, absorb nutrients through V-shaped grooves and micro-villi, and generate blisters when air flows through the micro-villi, which can improve convenience. Peel off the nutrients to facilitate the absorption of the mussels, which can reduce the pollution of the water body by feces, make the water body less prone to eutrophication, improve the living environment of the mussels and increase the output of the mussels.

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
