通过改换LEVAPOR生物膜科技改建地区污水净化设备

(PresseBox) (波恩, )
废水质量或者许可排放量的改变通常会要求提高污水净化设备能力。除去费用高昂的设备扩建,这些问题新近也可以通过设备改建,也就是对现有设备进行生物膜载体改造以较低费用得到解决。                                                                                                     
极其多孔的表面、12-15%的投放比、生物膜的快速形成以及较高的降解效率使LEVAPOR固定生物膜成为解决此类问题尤为合适的选择。

宁安硝化处理净化设备的改建 

为了能在冬季也能达到要求的CSB排放标准,牡丹江市决定通过LEVAPOR生物膜载体工艺对现有的宁安净化设备进行改建。400m³(12.5%)的LEVAPOR被投放进每天处理22,000m³污水的3,200 m³大小的生物反应器中。(图2)

尽管进水的CSB值波动很大(140到570mg/L)而且温度在+6°C与+20°C之间起伏,但是净化设备马上就能实现对CSB的最佳处理,排放值在3040mg/L之间(图3)。 

稍晚建成的更为敏感的硝化处理展现了同样好的效果,令人意外的是在通风池中也发展出了同步反硝化进程,大约50%形成的NO3N都得到了反硝化处理(图4)。             

地区污水净化设备改建的经济性

对净化设备进行改建只会因为12%到15%投放比LEVAPOR的载体原料以及载体的约束系统产生费用。通过LEVAPOR进行技术改建只需新扩建费用的大概30%到45%。价格低廉的反应器投放费用以及通风费用也为生物膜技术带来了更多的优势。
