At present, what are the better manufacturers of landfill leachate in China?

Landfill leachate is a kind of high-concentration organic wastewater with complex components and great changes in water quality and quantity. The main sources of landfill leachate are direct precipitation, surface runoff, surface irrigation, groundwater, moisture of garbage itself, moisture in covering materials and water produced by biochemical reaction of garbage.

At present, there are many processes: (pretreatment)+biochemical (including anaerobic and aerobic)+physicochemical (advanced treatment).

Among them, membrane modules "NF+RO" and "DTRO+RO" are the main advanced treatment methods.

Main problems in membrane technology;

The membrane module is expensive and the initial investment is high; The membrane element has high operating pressure and high power consumption.

High treatment; Leachate has high hardness and salt content, which is easy to cause pollution and membrane element blockage.

Frequent membrane cleaning produces a large amount of concentrated solution.
