The present invention relates to a kind of paper mill sewage treatment method, comprise the following steps：（1）Collect sewage；（2）Suspended material processing；（3）Dosing is degraded；（4）Microbial degradation；（5）Adjust pH；（6）Sterilization；（7）Discharge.A kind of paper mill sewage treatment method of the present invention can the higher papermaking sewage of Threshold retention, wastewater treatment efficiency is good, and effluent quality is good；The cost of water process can be effectively reduced, the effect of bacteria growing inhibiting can be effectively acted as, while makes the water quality after processing can iterative cycles utilization.
Description
Technical field
The present invention relates to sewage water treatment method, more particularly to a kind of paper mill sewage treatment method.
Background technology
China is the country of an extreme dehydration.Although fresh water total amount accounts for the 6% of global water resources, possess fresh water per capita
Amount is only the 1/4 of world average level, is 13, the whole world one of poorest country of water resource per capita." water " this be once considered as
Inexhaustible resource, serious restriction China's economic development is lacked unexpectedly, has had a strong impact on people's lives
Degree.Showing according to investigations, the phenomenon that China wastes water is very universal, and everybody does not produce enough attention also to water crisis, thus
The secondary use rate of water is relatively low.If recycling for water can be strengthened, sanitary sewage is regenerated and reuse, then this will be
Solve the best measure of water shortage problem, be the effective way for the sustainable development for realizing country, be Resources for construction economizing type, environment
The inevitable choice of friendly society.Sewage handling problem is increasingly subject to the great attention of society.With the continuous hair of paper industry
Exhibition, papermaking sewage amount discharge capacity are continuously increased, and papermaking sewage acidity is very high, and environmental pollution is serious, and it is a kind of to be badly in need of exploitation
The effect that deacidifies is strong, the low sewage water treatment method of cost of sewage disposal.
The content of the invention
The goal of the invention of the present invention is：For above-mentioned problem, the present invention provides a kind of high-efficiency environment friendly, green peace
Entirely, a kind of paper mill sewage treatment method.
The present invention is achieved by the following technical solutions：
A kind of paper mill sewage treatment method, comprises the following steps：
（1）Collect sewage：Sewage collecting is got up, is together put into treatment tank；
（2）Suspended material processing：Alkaline matter is added in treatment tank, stands 2h~4h, the alkaline matter is anhydrous
Calcium carbonate；
（3）Dosing is degraded：Sewage-treating agent is added in treatment tank, sewage-treating agent is polyvinyl alcohol, activated carbon and shell
Oligosaccharide mixture, the polyvinyl alcohol, activated carbon, the weight part ratio of chitosan are：50~55：5~7：8~9；
（4）Microbial degradation：By step（3）In sewage transport to biodegradable pond, by the method for microbial degradation, by dirt
Eutrophy composition oxidation Decomposition in water；
（5）Adjust pH：By step（4）In the pH of water adjust to 6.8~7.2；
（6）Sterilization：Use disinfection by chlorine；
（7）Discharge：Water discharge can be completed into sewage disposal.
Preferably, the step（2）In add alkaline matter in treatment tank, stand 3h, the alkaline matter is
Carbon Dioxide calcium.
Preferably, the step（3）In sewage-treating agent is added in treatment tank, sewage-treating agent is polyethylene
Alcohol, activated carbon and chitosan compound, the polyvinyl alcohol, activated carbon, the weight part ratio of chitosan are：52：6：8.5.
Preferably, the step（2）It is middle by step（4）In the pH of water adjust to 6.9.
The beneficial effects of the invention are as follows：
1. a kind of paper mill sewage treatment method of the present invention can the higher papermaking sewage of Threshold retention, while make processing
Water quality afterwards can iterative cycles utilization.
2. a kind of paper mill sewage treatment method of the present invention can effectively act as the effect of bacteria growing inhibiting.
3. a kind of paper mill sewage treatment method wastewater treatment efficiency of the present invention is good, effluent quality is good；Can effectively it drop
The cost of low water process.
