1. a kind of concentrate of landfill leachate integrates reducing device, it is characterised in that:

  • Including the level-one being mounted in rack (5)Colloid separation membrane element (1), two level colloid separation membrane element (2) and nanofiltration film unit (4);

    The level-one colloid separation membrane element (1) includes level-one water inlet pipe, filter (1-10), one-level booster pump (1-12), oneSection intake pump (1-4), two sections of intake pumps (1-6) and for concentrate carry out membrane filtration one section of CSM membrane module (1-3) and useIn two sections of CSM membrane modules (1-15) for generating concentrated water to one section and carrying out membrane filtration, the level-one water inlet pipe includes one section of water inlet pipe(1-9) and two sections of water inlet pipes (1-14) are connected with filter (1-10), one-level booster pump (1- in turn on one section of water inlet pipe (1-9)12) and one section of intake pump (1-4), and one section of water inlet pipe (1-9) is equipped at least on the pipeline of one-level booster pump (1-12) forepartTwo level-one dosing interfaces (1-11), the water inlet of one section of CSM membrane module (1-3) is connected with one section of water inlet pipe (1-9), clear liquidOutlet is connected with one section of clear liquid pipe (1-1), concentrated water outlet is connected with two sections of water inlet pipes (1-14) and one section of return pipe (1-5)Logical, one section of return pipe (1-5) is connected with the water inlet of one section of CSM membrane module (1-3) for concentrate recirculation through one section of circulating pump;

    Two sections of intake pumps (1-6), the water inlet and two of two sections of CSM membrane modules (1-15) are connected on two sections of water inlet pipes (1-14)Grade water inlet pipe (2-6) is connected, purified liquor outlet is connected with two sections of clear liquid pipes (1-2), concentrated water exports and level-one concentrated water discharge pipe(1-8) is connected with two sections of return pipes (1-7), and two sections of return pipes (1-7) are through two sections of circulating pumps and two sections of CSM membrane modules (1-15) water inlet is connected for concentrate recirculation;

    The two level colloid separation membrane element (2) is grading including two level water inlet pipe (2-6), two-stage supercharging pump (2-8) and twoWater pump (2-10) and the two level CSM membrane modules (2-3) for carrying out membrane filtration to one section of clear liquid, on two level water inlet pipe (2-6) successivelyTwo-stage supercharging pump (2-8) and two level intake pump (2-10) are connected with, two level water inlet pipe (2-6) pumps (2-8) forepart in two-stage superchargingPipeline be equipped at least one two level dosing interface (2-7), the water inlets of two level CSM membrane modules (2-3) and two level water inlet pipe(2-6) is connected, clear liquid mouth is connected with two level clear liquid pipe (2-1), concentrated water spout and three-level water inlet pipe (4-7) and two level return pipe(2-4) is connected, and two level return pipe (2-4) pumped through secondary cycle be connected with the water inlet of two level CSM membrane modules (2-3) it is generalIn concentrate recirculation;

    The nanofiltration film unit (4) includes three-level water inlet pipe (4-7) and three-level intake pump (4-8) and nanofiltration membrane component (4-9), three-level intake pump (4-8), water inlet and the three-level water inlet pipe of nanofiltration membrane component (4-9) are installed on three-level water inlet pipe (4-7)(4-7) is connected, purified liquor outlet is connected with three-level clear liquid pipe (4-1), concentrated water outlet is dense with three-level return pipe (4-2) and three-levelWater discharge spout (4-3) is connected, and water inlet phase of the three-level return pipe (4-2) through three-level circulating pump with nanofiltration membrane component (4-9)Connection is for concentrate recirculation.
