专利汇可以提供Processing method of laundry drain专利检索,专利查询,专利分析的服务。并且PURPOSE: To provide a less frequency of replacing the reverse osmosis film, by means of applying a reverse osmosis process and a concentration process, in a method of processing the laundry drain.
CONSTITUTION: The laundry drain in a laundry drain collector tank 1 is fed to an agglomeration and precipitation tank 19, with addition and mixing processed the agglomeration agent from an agglomeration agent tank 22 and the nutralization liquid from a neugralization liquid tank 23 respectively, and made an agglomeration and precipitation processing. A top clear liquid is carried into a circulation tank 3 through a transfer tube 20, being passed through a filter 4 and a high pressure pump 5 from said circulation tank, with a reverse osmosis processed by a reverse osmosis module 6, and a returning motion to said circulation tank repeatedly operated, thus making a work of concentration to the prescribed degree of concentration. The precipitated liquid in the bottom of the agglomeration and precipitation tank 19 is fed to an evaporator supply tank 7 through a transfer tube 21, together with a concentration material coming from the drain circulation tank 3, being evaporated and concentrated in an evaporator 9.
