Description
Technical field
The present invention relates to a kind of environmental protection technology and equipment, be specially a kind of thermal cycling and utilize industrial sewage treatment technology and device.
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 of carrying suspended particle and taking the water surface out of 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, 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, for papermaking and dyeing waste water, city domestic sewage, electroplating wastewater, fluoride waste etc., precipitate grain formation mud, 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 used for specific scope.
