Treatment of leachate from garbage disposal site
In recent years, with the acceleration of China's urbanization process, domestic waste treatment plants have blossomed everywhere. Landfill leachate has always been one of the most difficult wastewater treatment. From the initial single biological treatment to the current combined process, the treatment of landfill leachate Facilities need to be improved in design theory and methods
Landfill leachate is a kind of high-concentration organic wastewater with great harm. It has a brown or black appearance, a foul smell, and its components are complex. It contains a large number of toxic and harmful organic substances, high-concentration inorganic salts, and a variety of bacteria; its water quality is biodegradability Good, but it changes greatly, and changes with the changes of garbage composition, garbage treatment process, garbage storage time, season, climate, etc., and almost no periodicity.
Existing engineering practice shows that:
Qing Da Guohua Flat FilmMBRThe system has the following advantages in landfill leachate treatment:
（1） The process is simple, the structure is compact, the floor area is small, and it is not limited by the setting place. The bioreactor can maintain a high concentration of microbial biomass, the volume load of the treatment device is high, and the floor area is greatly saved.
（2） Can be used in conjunction with a variety of processes, such as: flat filmMBR Nanofiltration (NF) Combined process,SBR flat membraneMBRWait.
（3） The effluent quality is high quality and stable. Due to the efficient separation effect of the membrane, the separation effect is much better than that of the traditional sedimentation tank. The treated effluent is clearer than that, the suspended solids and turbidity are close to zero, and the bacteria and viruses are greatly removed.
（4） The treatment cost is lower than the tubular ultrafiltration membrane.
