Description
Technical field
The present invention relates to a kind of environmental protection equipment, be specially a kind of industrial sewage treatment system.
Background technology
Along with rapid development of economy, the sewage environmental pollution aggravation of the enterprise production process relevant to chemical industry, also more prevalent and serious to the harm of human health, in the sewage of wherein particularly discharging in fine chemical product (as pharmacy, dyestuff, daily use chemicals etc.) production process, the material that contains complex structure, poisonous and harmful and biological hard degradation, these wastewater treatment difficulty are very large.At present, the treatment technology of industrial sewage mainly contains following several.
1. the physical method such as filtration method, gravitational settling method and By Bubble-floating Method.Filtration method is to have impurity in the granular pellet layer trap water of hole, is mainly the suspended substance reducing in water; Gravitational settling method is to utilize the precipitable performance of suspended particle in water, and natural subsidence under the effect of gravity field, to reach solid-liquid separation; By Bubble-floating Method is to adsorb the attached method that suspended particle is taken the water surface out of of carrying of wrapping up in of micro-bubble by generation.These three kinds of physical method techniques are simple, and convenient management, but can not be applicable to the removal of solubility sewage composition has significant limitation, and leach thing and have secondary pollution.
2. coagulant sedimentation.Coagulant sedimentation is to utilize coagulating agent industrial sewage to be carried out to a kind of method of purifying treatment.Coagulating agent has inorganic polymer flocculant, organic polymer coargulator and biopolymer flocculation agent three major types conventionally.What aspect water treatment, be most widely used at present, is poly-aluminium salt and the compound poly-aluminium salt in inorganic polymer flocculant.Polymerize aluminum chloride (PAC), polyaluminium sulfate (PAS) are industrial most widely used two kinds of poly-aluminium salt.Experiment showed, that PAC has efficient flocculating effect to processing petrochemical wastewater, not only go turbid rate high, little on the pH value impact of former water, after processing, the colourity of water is good, can be used as the flocculation agent of petrifaction sewage recycling.These polyblend aluminium flocculation agents are widely used for processing drinking water, process water, waste water of mine, oil-containing wastewater, domestic water, natural Huanghe water, the Changjiang river Yuan Shui, dyeing waste water etc.But the processing cost of this treatment process sewage per ton is high, and throw out also can cause secondary pollution.
3. absorption method.Absorption method is to utilize sorbent material to process sewage.The more sorbent material of current industrial application has magnesium hydroxide, activated cellulose carbon (ACF) and novel sorbent material-chitosan and derivative thereof.Magnesium hydroxide is of wide application as acid industrial sewage treating agent, can precipitate grain formation mud for papermaking and dyeing waste water, city domestic sewage, electroplating wastewater, fluoride waste etc., and mud need filter and discharge.
4. biological process, is the organism utilizing in the metabolism Degradation and Transformation sewage of microorganism, makes it innoxious.Low by the biological process running cost of disposing of sewage, operational administrative is simple, but because microorganism there are certain requirements conditions such as nutritive substance, pH value, temperature, is difficult to adapt to that the chemical engineering sewage water yield is large, complicated component, toxicity are high, the feature of difficult degradation, and long processing period, there is secondary pollution in mud.
5. ion-exchange-resin process.Ion exchange resin (IER) is a kind of complex functionality macromolecular material that contains active group, and it is that crosslinked high-molecular copolymer introducing different properties ion-exchange group forms.Ion exchange resin has the functions such as exchange, selection, absorption and catalysis, in industrial sewage is processed, be mainly used in reclaiming heavy metal and your rare metal, purify toxic substance, remove acid or alkaline organic substance in organic sewage as phenol, acid and amine etc.At present, the ion exchange resin using in industrial sewage is processed has anionite-exchange resin, Zeo-karb, amphoteric ion-exchange resin, and range of application is little, has high input, and backwash meeting causes the very large waste of water resources.
6. membrane separation technique.In industrial sewage is processed, using membrane separating technology can be processed various sewage.Because Meteorological is high, treatment capacity is little, can only be for specific scope.
Summary of the invention
The object of the invention is organic, the inorganics sewage that contains decomposing for the high density producing in current chemical industry, medicine and other fields production process, high salt, difficulty, a kind of disposable treatment system is provided, treating processes does not need to add any treatment agent, there is no selectivity restriction, energy consumption is low, non-secondary pollution.
For achieving the above object, the present invention has adopted following scheme: industrial sewage treatment system, mainly by coal pulverizer, burner, sewage feeding pump, preheater, vaporizer, separator, vapour compressor, sewage (waste water) recirculating pump, discharge pump, wet-pit forms, coal pulverizer outlet connects burner, burner flame outlet connects incinerator, the outlet of sewage feeding pump connects incinerator top, sewage feeding pump water-in connects sewage lagoon, incinerator top exit connects preheater, in the chuck of incinerator, sewage outlet connects sewage (waste water) recirculating pump water-in, sewage (waste water) recirculating pump water outlet connects preheater, incinerator bottom is provided with mucking machine, preheater sewage outlet connects the import of vaporizer sewage, preheater condensation-water drain connects reuse water pipeline, vaporizer sewage outlet connects separator bottom, the outlet of separator overhead vapor connects vapour compressor steam inlet, vapour compressor air outlet connects vaporizer, evaporator condensation water out connects reuse water pipeline, separator bottom is provided with discharge pump and wet-pit, discharge pump outlet connects incinerator bottom, wet-pit outlet connects reuse water pipeline.
Described burner can use gas burner or oil fuel burner.
The top of described incinerator is provided with chuck, and chuck lower end is not exclusively closed.
During work, coal pulverizer is by coal pulverizer, and coal dust enters burning Indoor Combustion, and flame enters incinerator, the sewage of sewage lagoon is sent in incinerator chuck by sewage feeding pump, a small amount of sewage flows to downwards incinerator burner hearth from gap, chuck lower end, by flame, evaporated, in chuck, most of sewage is pumped into preheater by effluent cycle after being heated, flue gas and water vapor in incinerator enter preheater, sewage is further heated, preheater sewage out enters vaporizer, vaporizer sewage out enters separator, realize vapor-liquid separation, steam is by further heating up after vapour compressor, then send into vaporizer, sewage is further heated, vapour compressor makes formation negative pressure in separator, accelerated vapor-liquid separation, high-concentration sewage in separator is sent into combustion decomposition in incinerator by discharge pump, water of condensation in preheater, a small amount of water of condensation in water of condensation in vaporizer and separator all enters reuse water pipeline and sends into workshop reuse, waste residue in incinerator is discharged through mucking machine.
Owing to having adopted technique scheme, the progress that the present invention obtains is: processing industrial sewage does not need to add any treatment agent, there is no selectivity restriction, and energy consumption is low, and non-secondary pollution.
