1. , utilize suspension filtering film to realize the method that deep purification of waste water is handled, comprise in this method that the sewage that will finish through physical method after solid, liquid separates carries out water quality regulation, flocculation treatment, fine filtering step, is characterized in that:

  • 1. water quality regulation;

    the sewage that will finish after solid, liquid separates is introduced in the balancing tank (A1), and drop into the pH value conditioning agent, and fully stir,2. flocculation treatment;

    the sewage after the modifier treatment is drawn from balancing tank (A1), flocculation agent is dynamically sneaked into, enter to mix in the current stabilization jar (B5) by serpentine tube (B4) again and finish flocculation reaction and current stabilization by the injecting mouth (B2) on the aqueduct (A3),3. fine filtering;

    the throw out sewage that contains behind the current stabilization was moved the lower end water-in (15) that Lv Installed puts (C1) from suspension filtering film Zi and introduces, filtering layer is tackled formed suspension filtering film and is realized filter just in the middle of flocking filter cloth (4), upper strata haydite (3) realizes that the smart clear water of filtering leads to clean water basin (C5) from the top of this device, throw out moved the overflow type collecting sewage room (10) that Lv Installed puts (C1) from Zi and entered dust storage cabin (11) through blow-off pipe (12), was transported to filth storage can (C2) from blowdown discharge opening (18) again and did further aftertreatment.
