Modularized sewage biological treatment apparatus and technology

Abstract

A device of modular sewage biologic treatment includes pool, macroporous carriers and its immobilized microbion, inlet / outlet pipe, aeration pipe, filter, outlet damper, etc. It is easy to be dismounted and made up to get many different bed styles of immobile biological aerated filter (IBAF) according to the practical need. It is suitable for the recycle of organic sewage of high concentration and high amino-nitrogen specially.

Description

Technical field [0001] The invention relates to a sewage treatment device and process, in particular to a modular sewage treatment device and process. Background technique [0002] Sewage treatment is of great significance to the protection of my country's water resources and the sustainable development of my country's economy, and the efficiency of sewage treatment will be restricted by the level of corresponding equipment and technology. At present, there are three types of integrated reactors researched and developed at home and abroad: One is to remove COD and ammonia nitrogen. The characteristic of this type of reactor is that the traditional sewage treatment process is combined into one equipment, and the key treatment part is Contact oxidation method is still used; second, pretreatment is mainly used, mainly to separate solid impurities in sewage by physical and chemical methods, while taking into account the initial degradation of organic pollutants in sewage; third, it c...

AI Technical Summary

Problems solved by technology

The main problems of the above-mentioned integrated reactor are: (1) Due to the traditional aeration method, it is difficult to withstand high impact loads, resulting in poor adaptability of the equipment to changes in sewage, thus affecting its practical application; (2) the current Although some integrated reactors combine multiple independent processes in the same equipment in terms of structure, because each process is still combined with traditional processes, there are shortcomings such as insufficient compact structure and many auxiliary equipment; (3) Most integrated reactors are large in size, low in automation level, complicated in operation, and require professional personnel to operate and maintain, and the cost and operating cost of the entire reaction device are relatively high; (4) most of the integrated reactors are used to remove waste water Mainly COD, ignoring the removal of nitrogen and phosphorus pollutants in sewage, so the effect of water pollution treatment caused by eutrophication of water body is not good.
