Description
Technical field
The present invention relates to technical field of waste water processing, specifically a kind of Resourceful treatment method for high-salinity wastewater.
Background technology
High-salt wastewater is a hang-up of water treatment field always, and simultaneously also containing in organic situation, common water treatment method cannot reach treatment effect especially.Generally, common process many employings biochemical treatment of wastewater treatment, traditional biochemical processing method cannot reach processing requirements for high concentration hard-degraded organic waste water, this mainly because, hardly degraded organic substance is more difficult realization for the oxidizing reaction of microorganism, its stable benzene ring structure, backbone, or there is more functional group, all hinder the oxidising process of microorganism, if containing higher salinity in waste water, so unaffordable especially for microorganism, salinity in waste water can anti-bacteria consumingly, the Growth and reproduction condition of bacterium cannot be reached, finally cause the collapse of biochemical treatment system.And adopting anaerobic biological technique, the organic waste water for process high-concentration hardly-degradable can not have good hydrolytic action, if when salinity is higher, methanogen cannot normal growth, and anaerobic reaction is also a greater impact.Therefore, the organic wastewater with difficult degradation thereby for high density high salinity is difficult to adopt biochemical processing process.
Time biochemical method cannot carry out, physics and chemistry technology is seeming especially applicable.For the organic waste water of high density high salinity, the technology of current internal and international employing mostly is method of evaporation, reverse osmosis membrane filtration method, advanced oxidation processes, extraction process etc.Method of evaporation, mainly by reducing the means such as saturated vapor pressure, heating, realizing the concentrated of Pollutants in Wastewater and being separated, in engineer applied, often occur scale problems; Osmosis filtration method overcomes osmotic pressure by increasing pressure at one section of organic membrane, realizes water and organism, being separated of salt, the problem often occurring fouling membrane He scrap in engineering; Extraction is separation and the enrichment that the dissolubility difference utilizing solute in different solvents carries out pollutent equally, the case of extraction process domestic application is less, mainly because the water yield of waste water is larger, extraction agent costly simultaneously, and the requirement of engineering to reaction conditions is higher, although these methods can make the separated from contaminants in waste water, water quality is purified, but pollutent itself is change not, after concentrated, be still difficult to process, form secondary pollution.
Summary of the invention
The object of the present invention is to provide a kind of Resourceful treatment method for high-salinity wastewater, make effluent quality reach field irrigation water quality standard or industrial reuse water quality standard, realize recycling.
For achieving the above object, the invention provides following technical scheme:
A kind of Resourceful treatment method for high-salinity wastewater, by removing a part of suspended substance through quartz sand, activated carbon filtration after equalizing tank regulating water quality, then by electrodialyzer desalination, below the most ceiling value total salt content of waste water being dropped to artificial swamp water inlet total salt content, reduce COD, the BOD of waste water, total nitrogen, total phosphorus, suspended substance, organism and total salt through artificial swamp again, make effluent quality reach field irrigation water quality standard or industrial reuse water quality standard.
As the further scheme of the present invention: the most ceiling value of described artificial swamp water inlet total salt content is 1.5-2%.
Compared with prior art, the invention has the beneficial effects as follows: by equalizing tank, quartz sand filtration, activated carbon filtration, electrodialysis, artificial swamp, high-salt wastewater is processed, effectively reduce the COD of waste water, BOD, total nitrogen, total phosphorus, suspended substance, organism and total salt, make effluent quality reach field irrigation water quality standard or industrial reuse water quality standard, achieve the object of recycling; Especially facility cost and the carrying cost of wastewater treatment is also greatly reduced.
Accompanying drawing explanation

Embodiment
Below in conjunction with the embodiment of the present invention and accompanying drawing, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, in the embodiment of the present invention, a kind of Resourceful treatment method for high-salinity wastewater, by removing a part of suspended substance through quartz sand, activated carbon filtration after equalizing tank regulating water quality, then by electrodialyzer desalination, below the most ceiling value total salt content of waste water being dropped to artificial swamp water inlet total salt content, reduce COD, the BOD of waste water, total nitrogen, total phosphorus, suspended substance, organism and total salt through artificial swamp again, make effluent quality reach field irrigation water quality standard or industrial reuse water quality standard.
Embodiment 1
According to the feature of industrial park, Tuoketuo County high-salt wastewater, in Togtoh associating water utilities company limited, on-site has built 200m
2medium-sized facility, comprise tank, equalizing tank, quartz filter, activated charcoal filter, electrodialyzer, artificial swamp and millpond, the effect of each facility is as follows:
Tank: for hoarding waste water, avoids in waste water unprocessed just inflow living environment.
Equalizing tank: waste water is precipitated, dosing, mixing, neutralization, play the regulating effect of the water yield and water quality being carried out to pH, preaeration.
Strainer: strainer is indispensable a kind of device on delivery medium pipeline, plays while removing a part of impurity and larger molecular organics and plays again the effect preventing electrodialysis from blocking.
Electrodialyzer: utilize the selective penetrated property of semi-permeable membranes to be called electrodialysis to the method being separated different ions under electric field action.It is extensively used to seawater and brackish water desalination; Elementary desalination when preparing pure water and boiler, power-equipment are to fields such as water demineralizing are softening.But it to the removal of organism and nitrogen phosphorus without any effect.
Artificial swamp: the principle of artificial swamp waste water disposal facility is by manually building and controlling to run the ground similar with swampland, by waste water controlledly dosing on wetland, make waste water in wetland soil gap and the surperficial process flowed in a certain direction, utilize soil, artificial dielectric, plant, the physics of microorganism, chemistry, biological triple synergy, to a kind of technology that waste water processes.The mechanism of action of its ecosystem comprises absorption, delay, filtration, precipitation, microbial decomposition, conversion, redox, plant are covered, other effects etc. of residue accumulated, water transpiration and nutrition absorption and all kinds of animal.The pollutent that artificial swamp is removed is in extensive range, comprises N, P, S, organism, pathogenic agent etc.Under the condition that influent concentration is lower, the clearance of artificial swamp to biochemical oxygen demand (BOD) (Biochemical Oxygen Demand, BOD) can reach 60% ~ 85%, and the clearance of chemical oxygen demand (COD) (Chemical Oxygen Demand, COD) can reach more than 60%.
