THE POSSIBILITY TREATABILITY IN COMPLIANCE WITH THE COHESION PROPOSAL MIXTURE COMMITMENT WHERE THE BASICITY IS DIFFERENT

摘要

There is a kind of a kind of method of mixture of coagulator of different basicity by injecting, treatment for waste water is arranged to so that a turbidity appropriate can be removed, by injecting a kind of mixture of low alkalinity inorganic coagulant to prevent the excessive of inorganic coagulant from inputting and a kind of high alkalinity inorganic coagulant, it has 5% or more a basicity difference, or a scheduled mixing ratio is mixed to by a kind of a kind of mixture of inorganic coagulant of the injection with the low alkalinity in low alkalinity inorganic coagulant and a kind of inorganic coagulant with the high alkalinity in high alkalinity inorganic coagulant. It is being used for drinking water, sewage, or in the method by the treatment of the waste water of chemical treatment method, there is a kind of a kind of method of mixture of coagulator of different basicity by injecting, treatment for waste water includes that injection inorganic coagulant enters waste water, the growth suspended solid being suspended in waste water forms cotton-wool, precipitates cotton-wool. The method includes: the different basicity that a kind of mixture mixing for injecting inorganic coagulant enters waste water to a scheduled mixing ratio condense the suspended solid being suspended in waste water.
