8. storage tank water pump to enhance production of nanofiltration pressurized into reverse osmosis system by reverse osmosis, organic salt and high retention capacity, organic matter and further removal of salt. The design of reverse osmosis recovery rate reached 80%, the reverse osmosis system according to the design level two, system design operation pressure of 20 ~ 40bar, the effluent can reach the effluent quality requirements of this project, the reverse osmosis liquid to the reverse osmosis water tank reuse standard.

Sludge treatment process: using sludge thickening + dehydration + incineration treatment

    Main production structures and buildings:

The primary sedimentation tank, the regulating tank, the denitrification tank, the nitrification tank, the sludge thickening tank, the concentration liquid pool, the MBR membrane pool, the membrane treatment plant, the sludge dewatering room and the fan workshop.

    After the leachate is treated, the effluent quality standard should be up to the standard of "CJ25.1-89".

    This paper first introduces the background information of the design, and lists the relevant design basis and principles.

    Then, briefly introduces the feature of landfill leachate, and the leachate treatment technology such as aerobic treatment, anaerobic treatment, anaerobic aerobic treatment, physicochemical treatment and land treatment are analyzed and discussed.

The main part of this article will explain the basic principles of the process, the design process, the selection of related structures and equipment.

    In the appendix, this paper will give some illustrations of this process.
