Suizhou Municipal Committee visited the landfill leachate reconstruct and increment project site

Share to：

The Suizhou landfill leachate treatmentproject is reconstruction and increment project.

The COD of raw water is more than 5000mg/L,the landfill leachate was treated by two stages DTRO process, the capacity was100 tons per day.

With the increase of landfill leachateproduction, the original treatment equipment could not operate normally.

In 2016,Meifute took over and rebuilt theproject, replacing the DTRO membrane module which are fouling and aging.

And then, the treatment capacity ofleachate was increased to 220 tons per day, and the effluent quality reachedthe standard of "pollution control standard for domestic wastelandfill" (GB16889-2008).

In September 2016, Suizhou MunicipalCommittee visited the landfill leachate reconstruct and increment project site，and gave ahigh evaluation.

Index of water quality

Capacity	Index	Influent	Effluent

	BOD5(mg/L)	≤1500	≤30
	NH3-N(mg/L)	≤1200	≤25
	SS(mg/L)	≤1000	≤30
