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 by 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.
