生物滤池技术在污水处理中的应用

摘要：生物滤池技术是一种高生物量、高低负荷并存，采用气水反冲洗，应用规整波纹板、陶料等填料产生生物净化和过滤作用方法，可根据污水类型、进水水质指标组合不同的工艺进行处理。生物滤池技术处理生活污水，具有生物净化和过滤双重功效，对有机物和氮、磷具有较高的去除率，经工程实例监测结果表明，该技术处理效果好，运行稳定，各项指标均能达标，可以作为中水回用，缓解了水资源紧缺，减少了污水排放量，具有明显的社会效益、经济效益、环境效益，有一定的推广价值。

Application of Bio -filter Technology inWastewater Treatment

The biological filtration technology adopts air scour and water backwashing technology, using structured corrugated sheets and ceramic grains as packing for bio - purification and filtrations. It combined both high biomass and high low - rate trick- ling filtrations. According to the types of wastewater and the quality level of wastewater, the bio -flirtation technology can be used with other different techniques. Applying bio - filtration technology in sanitary sewage disposal, it has double effects of bio - puri- fication and filtration. Besides, it can achieve high removal rate for cleansing organic substance, nitrogen and phosphorus. The monitoring results of engineering examples proved that this technology has good effects, achieving stable operations with every in- dex reaching the standard level. It also could be used as recycled water, which settles the problem of water shortage, reduces the wastewater discharge. This method is economic as well as socially and environmentally friendly. The biological filtration technolo- gy is worth for promotion.
