Biological grid water body reinforcement purification and purifier

Abstract

A biological grid water body fortifying purification and its apparatus are disclosed. It forms self-fixing float filler, microbial membrane and spiral shell fed in ecological contact oxidation pool, biological filter area with lifting-flow suspended filler is set at outlet, the ecological contact oxidation pool is mad up of reinforced concrete structure, mesh blind flange on top of which is covered with vegetation layer on pool top. Its advantages include less mud output, better water quality purifying effect and low cost.

Description

technical field [0001] The invention relates to a method and a device for enhancing the purification of biological grid water body, which are mainly used in the enhanced purification of urban landscape water quality and ecological restoration, and belong to the field of environmental engineering and technology. Background technique [0002] Urban landscape water bodies have very important functions in ensuring regional water conservancy safety, improving environmental and ecological quality, and promoting the construction of water culture. Affected by human life, production activities and urban construction, the problems of environmental pollution, ecological degradation, and internal and external severance of many urban landscape water bodies in my country are relatively serious, which are prominently manifested in the decline in the capacity of water bodies to regulate and store runoff, and the ability to purify pollutants. Odor and algal blooms frequently broke out, result...

AI Technical Summary

Problems solved by technology

Mechanical filtration and physicochemical adsorption purification devices are effective in production and application, but there are problems with high operating costs, such as expensive materials for water purification and high power consumption, which are only suitable for enhanced purification of small landscape water bodies

Chemical algae killing and adding microbial agents can solve the problems of overgrowth of planktonic algae and promote the rapid decomposition of pollutants, but the addition of chemical agents and microbial agents is more expensive, and the risk of secondary pollution is high, so it is only suitable for small landscapes Water emergency treatment

Aeration and oxygenation have a good effect on improving the self-purification ability of water bodies and promoting the decomposition and transformation of pollutants, but aeration and oxygenation measures alone cannot solve the problem of enhanced purification of landscape water bodies, and there are problems such as high operating power consumption

The biological contact oxidation method has been successfully applied to the pretreatment of slightly polluted raw water. It is suitable for the water purification of relatively large water bodies. For the enhanced purification of pollutants such as phosphorus, the ecological chain (food chain) of pollutant output and transfer in the purification pool is relatively short, and a large amount of biofilm sludge generated during the purification process needs to be treated and disposed of, and the top of the pool emits odor, and the energy consumption of aeration and oxygenation and higher cost
