The absorbent module by feed liquor component, adsorbing separation pipe group, go out liquid component and be sequentially connected to form, the adsorbing separation
Guan Zuzhong is filled with adsorbent；The adsorbent is silica gel, macroreticular resin, activated alumina, one kind in activated carbon or two
The mixture of kind any of the above ratio；The mass volume ratio of the adsorbent and saponification liquor waste water is 1：0.2~1.6 (w/v, g/
mL)。
Wet method pressing mold molding procedure of the saponification liquor waste water of the present invention from magnetic materials production process, in wet method pressing mold
Saponified oil is added in molding procedure to be helped to demould, and saponified oil is dissolved in water generation white during mold is rinsed with water after demoulding
Emulsion, i.e., heretofore described saponification liquor waste water；
Saponification oil content is in 0.1~20g/ml in usual saponification liquor waste water；
Specifically, for example, the saponification oil component (mass percentage) is：AS oiliness improvers (70%), triethanolamine
(4%), 400# polyethylene glycol (6%), sodium nitrite (4%), EDETATE SODIUM (2%), BK fungicide (2%), Tween 80
(12%).
The advantage of the invention is that：
(1) for the present invention using flocculence demulsification saponification liquor waste water, treatment process process is simple, safe, of low cost, is applicable in
In industrially handling the saponification liquor waste water on a large scale；
(2) waste water after processing meets the waste water of national standard discharge, can feel at ease to discharge；
(3) place needed for practical saponification liquor waste water operations is small, economical and efficient.
(4) it illustrates
Fig. 1：Saponification liquor waste water without any processing；
Fig. 2：It is embodiment 2 and 4 respectively using flocculation adsorption method treated waste water.
(5) specific implementation mode
