Purifying treatment device

Abstract

The invention discloses a purifying treatment device which comprises a purifying cavity and a filter element arranged in the purifying cavity as well as a water outlet, a water inlet and an air inlet communicating with the purifying cavity. The water outlet is formed in one side of the filter element, and the water inlet and the air inlet are formed in the other side of the filter element; gas entering from the air inlet pushes water entering from the water inlet to the purifying cavity to be purified and continuously pushes the treated water to the water outlet to flow out. The purifying treatment device performs treatment by introducing water into the purifying cavity and meanwhile increases the oxygen content in water by means of gas, and the purifying treatment device has the advantages of being few in element, low in cost, simple to use, convenient to detach and the like.

Description

technical field [0001] The invention relates to the field of water body treatment, in particular to a purification treatment device. Background technique [0002] In the process of water body treatment, it is generally necessary to use a water pump to pass the water body into the water purification device, but in some special cases, such as: it is necessary to use water purification bacteria to decompose the waste in the water, or to feed animals in the water Organisms, in these special cases, also need to use the air pump to supply oxygen to the water purification bacteria or aquatic organisms in the water body. [0003] The most typical situation is aquaculture. The so-called "fish first raises water", the quality of water directly determines the success of aquaculture. There are a lot of harmful substances in the water of aquaculture, such as fish excrement, feed residues and other organic wastes are decomposed by anaerobic saprophytic bacteria in the water, which will m...

AI Technical Summary

Problems solved by technology

There are a lot of harmful substances in the water of aquaculture, such as fish excrement, feed residues and other organic wastes are decomposed by anaerobic saprophytic bacteria in the water, which will make the water rich in substances such as ammonia and nitrous acid. If there are too many substances such as ammonia and nitrous acid, it will lead to the lack of oxygen in the fish, which requires the use of nitrifying bacteria to oxidize and decompose the substances such as ammonia and nitrous acid in the water, and the nitrifying bacteria must be in a place with extremely high oxygen content Survival in the water body, and the survival of fish also requires the water body to be rich in oxygen. Therefore, it is not only necessary to use a water pump to pass the water body into a water purification device with nitrifying bacteria for water purification treatment, but also to use an air pump to pass through the water body. Inject gas to ensure the oxygen content in the water body, which leads to many problems such as too many components in the whole water body purification system, high cost, complicated use, inconvenient disassembly and washing, etc.
