Abstract
The present invention relates to a kind of solid-liquid separating agent of thick waste liquid, the mass percent of the binder is：Thick waste liquid 75-85%, flocculant I 12-20%, flocculant II 2 6%, pH adjusting agent.The preparation method of the release agent, preparation process are as follows：The preparation of inorganic polymer flocculant, the preparation of organic polymer flocculant, the mixing of flocculant and waste liquid.The technical program is the separation advantage in conjunction with inorganic flocculating agent, organic flocculant and high polymer coagulant, can effectively solve the problems, such as thick waste liquid difficulty separation, have the characteristics that investment is small, at low cost, easy to use, separating effect is notable, can use at normal temperatures.
Description
Technical field
The present invention relates to a kind of solid-liquid separating agent, especially a kind of solid-liquid separating agent of thick waste liquid.
Background technology
Compared with other industry, pharmacy waste water, livestock-raising waste water and amylum wastewater are thick solid-liquid mixing
Waste liquid, complicated component, peculiar smell are big, coloration is deep, are always China's pollution most serious, most intractable industrial wastewater.Especially
There is a large amount of organic matter difficult to degrade in pharmacy waste water, livestock-raising waste water and amylum wastewater（Such as phenols, quinones）, meeting
The generations such as soil, air, underground water are seriously affected.Currently, the process problem of thick waste liquid solves to have become full society in time
The emphasis and hot spot that can be paid close attention to are not only the needs of environmental protection, the essential condition of even more related July sustainable development.Cause
This there is an urgent need to a kind of solid-liquid separating agent of thick waste liquid, puts into the processing of waste liquid instantly, existing this to change
Awkward situation.
Invention content
Present invention aim to address defect in the prior art, a kind of environmental pollution that can effectively reduce waste water is provided and is asked
Topic, and solid-liquid separating agent easy to use, at low cost.
A kind of thick waste liquid solid-liquid separating agent, the mass percent of component are：
Water 75-85%, flocculant I 12-20%, II 2-6% of flocculant, wherein flocculant I are inorganic flocculating agent, and flocculant II is
Organic flocculant.
The flocculant I is the polymerization ferrous sulfate in inorganic flocculating agent.
The flocculant II is the polymerization of acrylamide in organic flocculant.
A kind of preparation method of thick waste liquid solid-liquid separating agent, preparation process are as follows：
1）The preparation of inorganic flocculating agent：Flocculant I is heated to 40-50 DEG C under a small amount of water stirring, waits for whole dissolvings
Afterwards, spare after stirring 5-15min under keeping warm mode；
2）The preparation of organic flocculant：Flocculant II is heated to 25-40 DEG C under a small amount of water stirring, waits for whole dissolvings
It is spare afterwards；
3）Flocculant mixes：By above-mentioned steps 1 in the state of stirring）The flocculant I prepared is slowly added in flocculant II,
PH is adjusted after uniform solution to be formed, after being cooled to room temperature to neutrality as finished product.
Above-mentioned pH adjusting agent is technical grade solid.
The solid-liquid separating agent of the present invention is suitable for pharmacy waste water, livestock-raising waste water, starch wastewater etc. or its mixed waste liquor
Processing.The present invention is compound using organic and inorganic flocculating agent, the advantages of having both inorganic and organic polymer coargulator, while gram
Take single flocculant there are the shortcomings that.Is all had by good clean-up effect while being had for various industrial sewage and invests small, cost
The features such as low, easy to use.

In acrylamide, double centner is added water to after uniform solution to be formed, pH is adjusted after being cooled to room temperature to neutrality as finished product.
Embodiment 2：
1）The preparation of inorganic flocculating agent：It weighs 12 kilograms of polymerization ferrous sulfate and is heated to 40-50 under a small amount of water stirring
DEG C, it is spare after stirring 5-15min under keeping warm mode after all dissolving；
2）The preparation of organic flocculant：It weighs 3 kilograms of polymerization of acrylamide and is heated to 25-40 DEG C under a small amount of water stirring,
It is spare after all dissolving；
3）Flocculant mixes：By above-mentioned steps 1 in the state of stirring）The polymerization ferrous sulfate prepared is slowly added to polymerization third
In acrylamide, double centner is added water to after uniform solution to be formed, pH is adjusted after being cooled to room temperature to neutrality as finished product.
