Description
Technical field
The invention belongs to technical field of sewage more particularly to a kind of sewage treatments that COD ss suspended solid is effectively reduced
Device.
Background technique
Trade effluent refers to the sewage and waste liquid generated in industrial processes, wherein containing the industrial production outflowed with water
The pollutant generated in materials, intermediate product and product and production process.With industry rapid development, the type of sewage and
Quantity rapidly increases, also increasingly extensively and serious to the pollution of water body, threatens the health and safety of the mankind.Therefore, for protection
For environment, the processing of trade effluent is more even more important than the processing of municipal sewage.With economic fast development, people's lives water
Flat constantly to be promoted, the requirement to ecological environment also increasingly improves, therefore more and more trade effluent needs are up to standard by handling
After discharge.
Dyeing and printing sewage processing is exactly one kind of Industrial Waste Water Treatments.Dyeing and printing sewage water quality is complicated, pollutant main source are as follows:
Entrainment of the one kind from fibrous raw material itself；Another kind of is slurry used in process, finish, dyestuff, chemical assistant
Deng.Dyeing and printing sewage water is big, organic pollutant content is high, coloration is deep, alkalinity and pH value variation greatly, change of water quality it is violent, suspension
Object content is high.Currently, the common method of processing sewage is roughly divided into three kinds: 1, utilizing the organic matter in microorganism removal sewage
Biological mode；2, using coagulation, air bearing, precipitating, filters mechanical treatment；3, the life of film, bag, porous material absorption is utilized
Change the materilization freatment method combined with physics to reduce COD, meets discharge standard.Currently, plate and frame pressure mud machine be it is a kind of with
The machinery that sludge is major function is squeezed, mechanical force is applied by side and realizes squeeze and filter process, mud is carried out to sewage-mud
Water separation.It is mainly characterized by that occupied area is small, and squeezing area is big, the disadvantage is that exhalant canal is not smooth, discontinuous work,
It cannot be used in the technique of drainage as the main purpose.
