Description
技术领域technical field
本实用新型涉及污水处理领域，特别涉及一种缺氧池射流搅拌装置。The utility model relates to the field of sewage treatment, in particular to a jet stirring device for anoxic pools.
背景技术Background technique
我国对控制氨氮的排放越来越重视，而在众多的污水脱氮技术中，二级生物处理法仍旧是运用最为广泛且有效的方法。传统的生物脱氮工艺包括硝化过程和反硝化过程两个部分。硝化过程是自养型的亚硝化细菌和硝化细菌在好氧条件下，将水中NH3-N转化为NO2-N和NO3-N的过程，期间消耗碱度；反硝化过程是在缺氧条件下，异养型的反硝化细菌利用有机碳源作为电子供体将硝化过程产生的NO2-N和NO3-N转化为N2的过程，期间产生碱度。因此，缺氧单元对于生物法去除TN和为硝化过程补充碱度十分重要。而由于反硝化过程对于有机碳源的需求，工程上习惯将缺氧单元置于好氧单元之前，以实现污水中有机碳源的充分利用。因此，为了完成生物脱氮，需要将好氧单元中富含NO2-N和NO3-N 的硝化液回流至缺氧单元。my country pays more and more attention to the control of ammonia nitrogen discharge, and among the many sewage denitrification technologies, the secondary biological treatment method is still the most widely used and effective method. The traditional biological denitrification process includes two parts: nitrification process and denitrification process. The nitrification process is a process in which autotrophic nitrosative bacteria and nitrifying bacteria convert NH 3 -N in water into NO 2 -N and NO 3 -N under aerobic conditions, during which alkalinity is consumed; denitrification process is in the absence of Under oxygen conditions, heterotrophic denitrifying bacteria use organic carbon sources as electron donors to convert NO 2 -N and NO 3 -N produced in the nitrification process into N 2 , during which alkalinity is generated. Therefore, the anoxic unit is very important for the biological removal of TN and the supplement of alkalinity for the nitrification process. Due to the demand for organic carbon sources in the denitrification process, it is customary in engineering to place the anoxic unit before the aerobic unit to achieve full utilization of organic carbon sources in sewage. Therefore, in order to complete the biological denitrification, it is necessary to return the nitrification solution rich in NO 2 -N and NO 3 -N in the aerobic unit to the anoxic unit.
针对水量波动大、氨氮含量高、有毒有害物质含量相对低的分散型农村生活污水处理，以传统生物处理方法为主要处理工艺的一体化污水处理设备得到了广泛的开发和应用。然而对于一体化污水处理设备缺氧单元的搅拌，往往采用在池底铺设穿孔管进行曝气搅拌的方式，这一方面增加了设备投资和运行成本，另一方面也加大了缺氧单元溶解氧含量过高的风险。而土建工程中常用的机械搅拌，从技术和经济角度都不适合用于高集成度的一体化污水处理设备。For the decentralized rural domestic sewage treatment with large fluctuations in water volume, high ammonia nitrogen content, and relatively low content of toxic and harmful substances, integrated sewage treatment equipment with traditional biological treatment methods as the main treatment process has been widely developed and applied. However, for the agitation of the anoxic unit of the integrated sewage treatment equipment, the method of aeration and agitation by laying perforated pipes at the bottom of the pool is often adopted. Risk of high oxygen levels. The mechanical agitation commonly used in civil engineering is not suitable for highly integrated integrated sewage treatment equipment from a technical and economic point of view.
