Weight, threatens the health and safety of the mankind.Since the ingredient of industrial wastewater is more complicated, some are also toxic, Industrial Wastewater Treatment ratio
Municipal wastewater processing is more difficult also more important.Alcohol waste water be high concentration, high-temperature, high suspended matter organic wastewater, handle skill
Art starting is more early, and development is very fast.Waste residue in waste liquid contains the crude fibres such as smashed cassava skin, rhizome, this substance is useless
It is insoluble COD in water；Cellulose and hemicellulose in cassava are polysaccharose substances, can't be ferment in alcoholic fermentation
The carbon source of female bacterium and be utilized, remain in waste liquid, show as dissolubility COD；The sediment contamination of inorganic ash content.These substances increase
The difficulty of wastewater treatment is added.Current patented technology mostly biases toward flocculation adsorption and the technique that precipitates, such as Patent No.
CN201210483774, CN201510220252 etc. are all based on flocculation adsorption CODcr, and then improve the removal effect of CODcr
Rate.But the effect of these treatment process removal is not it is obvious that causing subsequent biochemical load still very high.So present market
Be highly desirable to it is a kind of can not only take into account flocculation, but also can efficiently remove the waste water treating agent of CODcr.
Application No. is 201611004386.9 Chinese patents to disclose a kind of alcohol waste water treatment process, specifically according to such as

Section；(2) a heavy pond then is lifted into pump to be pre-processed, add in this stage in order to remove insoluble COD in waste water
Enter inorganic agent, to guarantee effective removal effect；Inorganic agent is added in alcohol waste water；(3) waste water after carries out entering hydrolysis
Acidification pool and contact-oxidation pool carry out biochemical treatment, and water outlet enters secondary settling tank and carries out mud-water separation.Sludge a part of secondary settling tank
Before being back to aerobic tank, a part drains into sludge-tank；(4) after the sludge concentration progress sludge press filtration dehydration that each stage generates just
Can be transported to landfill or burning outside, but the technique that provides of the invention to removal effect especially organic matter dissolved matter removal rate and
There are also rooms for promotion for turbidity removal rate.
