Background technology
In water treatment method, flocculence is one of important method.Present employed flocculation agent and coagulant aids are mainly mineral compound and artificial synthetic organic materials.The inorganic flocculating agent consumption is big, easily produces secondary pollution, and the particularly extensive application of aluminium salt becomes increasingly conspicuous to the influence of environment, especially to the processing of tap water, uses aluminium salt in a large number, can cause the senile dementia sickness rate to rise.Because most of synthetic macromolecular organic compounds are as the use of flocculation agent or coagulant aids, the monomer that remains in the water has toxicity, is detrimental to health, as the polyacrylamide of present widespread usage.The research of current emerging biological flocculant has caused people's attention, and it has effect stability, biodegradable, non-secondary pollution, excellent characteristic such as safe and harmless.Because biological flocculant still is in conceptual phase, and industrial scale is little, cost is big, fails to be used widely at present.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the purpose of this invention is to provide by waterplant being carried out the preparation method of a kind of natural biological coagulant aids that modification develops.Another object of the present invention is to solve the excessive and raising drinking water safety problem of the flocculation agent consumption that exists in the flocculation technique in the existing water treatment procedure.
For achieving the above object, technical scheme of the present invention provides a kind of preparation method of natural biological coagulant aids, and this method may further comprise the steps:
(1) gathering of raw material: gather, fish for the algae in 4 ~ 8 degree Beaume bittern of salt pan;
(2) to the pre-treatment of above-mentioned raw materials: the algae of fishing for is placed on the mesh screen, with former bittern dash drench clean, air-dry then; Place air seasoning place to preserve;
(3) pulverization process: be ground into the algae after air-dry Powdered;
(4) modification, water bath processing: place modification liquid to boil 1 hour in above-mentioned algae powder, be cooled to soak at room temperature then 24 hours; Described modification liquid is for being mixed with 0.1 ~ 1% solution with one of commercially available ammonium acetate, water glass, potassium permanganate;
(5) separating treatment: aforesaid liquid earlier with the screening of 70～100 μ m bolting silks, is removed the macrobead foreign material; Use 20～30 μ m membrane filtrations then;
(6) the pH value is adjusted: use water glass to adjust that the pH value of liquid is 6.5～7.5 after the above-mentioned filter;
(7) seal up for safekeeping, take care of: add 40ppm formaldehyde, seal up for safekeeping then in plastic containers, In Shade preservation is standby.
Characteristics such as effect of the present invention is that this prepares in the method for natural biological coagulant aids, and raw material obtains easily, is a kind of coagulant aids that cooperates aluminum salt flocculant to use, and this method uses material quantity few, and it is wide, easy to use to adapt to the PH scope, and complete processing is simple, and is safe and harmless.Can make the usage quantity of aluminium salt reduce by 50～70% by adding this biological coagulant aids.And can meet or exceed the flocculating effect of a large amount of aluminum salt flocculants of independent use.
