Description

Water purification system

technical field

The utility model belongs to the field of water treatment, in particular to a water purification system.

Background technique

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.

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, the dissolved oxygen in the water body is quickly consumed, making the water body present in an anoxic or even anaerobic state, and the ammonia nitrogen content is greatly increased, resulting in algae A large number of breeding, eutrophication of the water body, the transparency of the water body is also sharply reduced, and even black and smelly. Therefore, how to solve the water environmental pollution and habitat degradation of closed water bodies has become an important environmental problem that needs to be faced urgently.

For the treatment of closed water bodies, the key is to solve two problems: one is to increase the dissolved oxygen in the water body, and the other is to improve the biological activity of the water body. Based on these two key issues, the aerated biofilm system has undoubtedly become a closed water purification system with good applicability, and has become a commonly used technical system for closed water bodies.

However, as far as the existing aerated biofilm systems are concerned, there are still the following deficiencies: (1) The aeration devices commonly used at present can be divided into diffuse flow aeration devices, pure oxygen microporous aeration devices and swirl aeration devices wait. 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 aeration energy consumption of the existing cyclone aeration device is relatively high. 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, thereby achieving 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 use, 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.
