Township landfill leachate comes from the moisture contained in the garbage itself in the township landfill, rain and snow water entering the landfill and other moisture, excluding garbage and cover土层的Saturated water capacityAnd through the garbage layer and overlying soil layer to form a high concentration of organic wastewater, its pH value is between 4 and 9, COD is in the range of 2000 to 62000mg/L, BOD5 is from 60 to 45000mg/L, is a complex composition of high concentration organic wastewater。Leachate treatment system is the key to the success of landfill technology, if not treated directly into the environment, will cause serious problemsEnvironmental pollution。
"Domestic waste Landfill Pollution Control Standards" (GB16889-2008) for the construction of landfill pollution standards for the detailed specification。The standard stipulates that existing and new domestic waste landfills should have more complete sewage treatment facilities, and the leachate can be directly discharged after treatment to reach the emission limit specified in the standard。
Our company adopts the "biological pretreatment + two-stage DTRO (dish tube reverse osmosis)" treatment process, and the effluent water quality can stably meet the requirements of Table 2 in the "Domestic Waste Landfill Pollution Control Standard" (GB16889-2008)。The process greatly reduces the load of pollutants, conductivity and total hardness of DTRO membrane influent through biological pretreatment，The water yield and operation stability of DTRO membrane are improved，The backwash cycle of DTRO film is delayed.DTRO membrane compared to roll RO membrane，It has the advantages of high operating pressure, wide circulation channel, strong blowdown capacity, and strong maintenance and cleaning tolerance，More suitable for township garbage leachate characteristics。
The Internet + operation control service provided by our company completely eliminates the operational difficulties of customers。
