Bacteria release device

Abstract

The invention provides a bacteria release device, comprising a barrel-shaped holder, a buoyancy module prepared from a material capable of providing buoyancy such that the barrel-shaped holder floats in a water source, a bacteria culture medium surrounding the buoyancy module along the circumference of the buoyancy module for providing bacteria to decompose contaminants in the water source, and a degradable shell surrounding the bacteria culture medium along the circumference of the bacteria culture media for wrapping the bacteria culture medium in the degradable shell; due to the barrel-shaped holder and the buoyancy module, bacteria are able to be released while floating and rolling in the water source. Due to the degradable shell used for covering the outside of the bacteria culture medium, the bacteria can be gradually released when floating in the water source. As the shell degrades, the bacteria are gradually released, thereby gradually decomposing the contaminants in the water source.

Description

technical field [0001] The invention relates to the technical field of water pollution treatment, in particular to a bacteria feeding device. Background technique [0002] Since the protection of water sources has not received enough attention for a long time, drinking water sources are generally polluted, and a large variety of trace organic pollutants that are poisonous to the human body have been found in drinking water, such as carcinogenic, teratogenic, mutagenic substances, and chlorination. Disinfection by-products. Under this background, the ozone-granular activated carbon treatment process was developed, which played a better role in ensuring the quality of drinking water. With the development of water quality detection technology, many new water quality problems have been discovered, such as Giardia and Cryptosporidium (two insects), Daphnia, red worm, water biological stability, high ammonia nitrogen content, etc. Wait. For this reason, countries all over the w...

Problems solved by technology

However, the ability of ultrafiltration alone to remove dissolved organic matter in water is very limited, especially small molecular weight and easily biodegradable organic matter, which can hardly be removed by ultrafiltration

However, this part of small molecular weight organic matter will cause water biological stability problems, causing bacteria to multiply in the pipe network again, deteriorating water quality

At the same time, ultrafiltration cannot remove ammonia nitrogen
