Process Flow Chart of DTRO+STRO Containerized Leachate Treatment System

All above processes can meet the leachate discharge standards.

Leachate Treatment Process for MSW Incineration Sites

• The balance tank and grid sand-sedimentation tank mainly remove silt in the original filtrate and homogenize and equalize the feed water.

• Anaerobic UASB mainly removes pollutants such as COD, with a removal rate of 75%-90%.

• MBR mainly consists of denitrification tank, nitrification tank, and an external ultrafiltration system, mainly removing ammonium nitrogen (with a removal rate of 99%) and the remaining COD from leachate.

• The biological pre-treated effluent enters the DTRO/STRO membrane system. The DTRO/STRO system consists of high pressure STRO/DTRO membrane modules.

Leachate Treatment Process for MSW Landfill Sites

• The balance tank and grid sand-sedimentation tank mainly remove silt and homogenize and equalize the raw water.

• The hydrolysis tank mainly improves the biodegradability of the leachate.

• MBR consists of denitrification tank, nitrification tank, and an external ultrafiltration system, which is used to remove ammonium nitrogen (with a removal rate of 99%) and the rest COD from leachate.

• The biological pre-treated effluent enters the DTRO/STRO membrane system. The DTRO/STRO system consists of high pressure STRO/DTRO membrane modules. The DTRO/STRO membrane system can achieve water production rate of over 80% and reach different effluent standard.
