摘要:
长沙市固体烧毁物处置场的渗滤液处置分厂呈现了纳滤膜压力上涨快、膜两头压差高、化学清洗频仍等出产困难，经由过程外不雅检测、无机物截留率检测和探针测试，发觉该膜进水端第一节膜元件质量增添了6.67%，对无机物的截留率为87.03%，清液出水偏黄。取污染物检测阐发，发觉是微生物滋长所发生的生物黏泥，注解该厂膜元件具有严峻的微生物污染和必然水平的不成逆氧化破坏。经由过程投加非氧化性杀菌剂，有用按捺了微生物的滋生，同时经聚酰亚胺修复剂对纳滤膜进一步修复后，该膜对无机物的截留率提高到了92.73%，出水清亮。
Abstract:
The nanofiltration membrane integrated unit in the leachate treatment of the solid waste treatment plant in Changsha City has experienced production problems such as fast increasing pressure, high pressure difference across the membrane, and frequent chemical cleaning. Visual examinations, organic matter retention test, and probe test were implemented. The results showed that the weight of the first membrane element increased by 6.67%, the rejection rate of organic matter was 87.03%, and the effluent was yellowish. Analysis of the pollutant revealed that the pollutant was biological slime produced b����APPy the microorganism. The results showed serious microbial contaminations and a certain degree of irreversible oxidative damage. Dosing nonoxidative fungicides effectively inhibited the propagation of bacteria. Meanwhile, the nanofiltration membrane was repaired with a polyimide repair agent. The retention rate increased to 92.73%, and the effluent was clear.
