Description
Technical field
The utility model is related to a kind of sewage disposal system, more particularly to a kind of carbide acetylene chemical engineering sewage zero discharge treatment
System.
Background technology
The Coal Chemical Industry new technology of calcium carbide method acetylene production, has overturned the coal gasifying process of Coal Chemical Industry upstream, with wide
Application prospect.Country proposes strict requirements to newly-built Coal Chemical Engineering Project with water and Sewage Water Emissions, it is desirable in enterprise
Portion's waste water realizes zero-emission.Therefore, sewage zero-discharge treatment is can't steer clear of in the popularization and application of acetylene from calcium carbide Coal Chemical Industry new technology
Technical problem.
Generally, carbide acetylene chemical engineering sewage (including production waste water, sanitary sewage and peace and quiet lower water etc.) is by one
Its main contamination index COD can be reduced to 50mg/L or so, ammonia nitrogen drop after level pretreatment, secondary biochemical treatment and advanced treating
As little as 5mg/L or so, phenol are reduced to below 0.5mg/L, but salt content is still higher, it is necessary to be carried out at desalination after advanced treating
Reason, the desalination Water circulation after desalination, strong brine is generally required and is evaporated condensing crystallizing, finally realizes zero-emission.
To realize the zero-emission of waste water, New Coal Chemical enterprise is by salt content water higher and through organic after advanced treating
Waste water is further processed, and is carried out frequently with two sections of " less salt water process+strong brine curing process ".Each section of conventional treatment technology and master
Want function as described below：
Less salt water treatment stage, the conventional treatment technology of the section is mechanical filter+decalcification magnesium technology+film concentration, wherein mechanical mistake
The purpose of filter is further to remove suspension and colloid in waste water；Decalcification, magnesium technology, main purpose are to realize the removal of calcium, magnesium,
Subsequent treatment section scale problems are prevented, film concentration is the reclamation rate that brine concentration is further improved water.Strong brine curing process
Section, the conventional treatment technology of the section is mechanical vapor or evaporation pond, and wherein mechanical vapor is that the crystallization of salt is realized using steam, evaporation
The pool is to utilize solar energy, under field conditions (factors) gradually evaporates strong brine high, realizes the crystallization of salt.At present, strong brine solidification is more
Using evaporative crystallization, mainly include multiple-effect evaporation technology and mechanical vapor recompression technology, this two classes technical matters is ripe, can root
According to actual conditions, suitable evaporation technique is selected.The sewage zero-discharge processing system that the utility model is related to focuses on low-solids water

Treatment, for example with techniques such as coagulating sedimentation, multi-medium filtering, charcoal absorptions, it is therefore an objective to remove suspension, the glue in water
Body material, when using embrane method as desalinating process, in addition it is also necessary to sofening treatment, calcium, magnesium, silicon in removal sewage are carried out to water
Deng material, suppress pollution of such material to film.
The shortcoming of above-mentioned prior art：
Ion-exchange has that occupation area of equipment is big, system operation maintenance is frequently complicated.Also, ion is handed over
Once changing resin adsorption saturation, it is necessary to regenerate, substantial amounts of regeneration liquid waste is produced, therefore effluent quality is also in cyclic fluctuation,
Need to add flocculant during regeneration and expend substantial amounts of soda acid, be unfavorable for environmental protection；Meanwhile, ion-exchanger be generally diameter compared with
Big tank body, volume is big, weight is big, not readily transportable and installation and debugging, long construction period.
Requirement of the membrane separation process to the quality and water of film is very high, it is necessary first to content of organics is dropped to it is very low, otherwise
Organic matter can form dirty stifled in film concentration, decline membrane lifetime shortening, aquifer yield, and the hardness of waste water can rise in film concentration
Height, easily crystallization, and the fouling on film, makes film lose concentrating capacity.
