Water purification system

Abstract

The invention provides a water purification system, belonging to the field of water treatment. The water purification system comprises an oxygenation device and a microbial carrier device, wherein the oxygenation device comprises an air compressor, a magnetic assisted cyclone gas dispersion pipe and a gas inlet pipe connected between the air compressor and magnetic assisted cyclone gas dispersion pipe; the microbial carrier device comprises a floating barrel, a basalt fiber carrier and a concrete precast block; the upper and lower ends of the basalt fiber carrier are respectively connected with a floating ball and the concrete precast block; and the basalt fiber carrier is suspended in water. Sewage forms abundant gas bubble flow after passing through the magnetic assisted cyclone gas dispersion pipe, and submarine aboriginal microbes are attached to the basalt fiber carrier and perform massive reproduction. The water purification system can increase the dissolved oxygen concentration in the water body and the aboriginal microbial biomass in water. The microbubbles are utilized to oxidize the sediment and reduce the endogenous pollution, and the microbes on the carrier are utilized to degrade the pollutants in the water body, thereby implementing efficient and quick purification of the pollutants in the closed water body.

Description

technical field [0001] The invention belongs to the field of water treatment, especially a water purification system Background technique [0002] For a long time, due to the lack of systematic, coordinated and innovative scientific research on the problem of closed water pollution, the technology for the prevention and control of closed water pollution is relatively weak. In addition, most closed water bodies are slow-flowing waters, and the environmental capacity is small , The self-purification ability is poor, and it is very easy to be polluted, which leads to the increasingly serious pollution of this type of water body and has not been fundamentally reversed. [0003] The pollution sources of closed water bodies mainly come from industrial wastewater, domestic sewage, and dust-carrying pollution caused by wind and sand. When the total amount of pollutants entering the water body exceeds the self-purification capacity of the dissolved oxygen content in the water body, ...

AI Technical Summary

Problems solved by technology

Among them, the diffuse flow aeration device has a large flow rate, but the oxygen mass transfer efficiency is low; the microporous aeration device has high oxygen mass transfer efficiency, but it is easy to block and inconvenient to clean; the swirl flow aeration device has the advantages of large flow rate and is not suitable for blockage , but the existing swirl aeration device has high aeration energy consumption

Moreover, during the installation process of these aeration devices, they are mostly located in the middle of the water body, so it is difficult to quickly and effectively oxidize the sediment and improve the habitat conditions of the water body, so as to achieve the purpose of purifying the water body

(2) Most of the biofilm fillers currently used are artificial composite materials, which lack consideration in terms of environmental friendliness

During the use process, some biofilm fillers are left in the water body, which may cause new impacts on the water quality or the ecological environment.

Moreover, the structural fabrication and installation methods of biofilm fillers are mostly simple transplantation of sewage treatment projects, which cannot meet the needs of eutrophic closed water bodies with low organic pollution.
