That soil irrigated land treatment method method is the earliest human use of sewage treatment, but the application of land treatment system common in urban sewage treatment. For the treatment of leachate river sewage treatment methods, the collected leachate chemical wastewater treatment approach, through sprinkler reflux to landfill. Landfill leachate recirculation garbage humidity due to an increase, thereby increasing the biological activity, accelerate methane production and decomposition of waste. Second, because the sprinkler evaporation, so that leachate volume decreases, beneficial to the operation of the wastewater treatment system, and can save energy costs. North of England Seamer Carr landfill leachate recirculation using part, COD value of 20 months after the leachate recirculation zone is reduced more, the metal concentration has decreased substantially, and NH3 -N, Cl- concentration small changes. Description declining metal concentration is not only due to the dilution effect caused by the waste may also be caused by inorganic components of their adsorption. Because leachate recirculation has many advantages, so the design of the landfill at the top do not all closed, but should establish regular arrangement of the channel in order to avoid contamination of the surrounding water. Low concentrations of leachate can not be directly discharged due to NH3-N, Cl- concentration is still high, the temperature is low season simple sewage treatment methods, less evaporation, biological activity is weak, leachate recirculation effect needs further study. Quality control integrated wastewater treatment equipment: 1, factories and factory acceptance test: in need of specialized tests made at the specific request. In general requirements for factory testing integrated wastewater treatment equipment are prescribed. Seller shall report the test schedule and invite the buyer to take the test; factory acceptance buyer must participate. 2. Tests on Completion: In general requirements for integrated wastewater treatment equipment startup, testing and inspection requirements were specified, field testing of specific devices and equipment requirements were specified in the relevant sections. 3, the seller shall be responsible for the integrated wastewater treatment equipment for all materials, processes, equipment and measuring instruments for routine testing of sewage treatment methods, sampling and testing to ensure quality and meet the terms of the requirements. 4, the seller shall be responsible for the establishment and implementation of a certain quality control procedures integrated wastewater treatment equipment. To ensure that all work meets the contract requirements. This responsibility includes both the seller his work, including subcontractors or other suppliers work.
