Description

Heterogeneous strengthening divides leads circulation anaerobic granulating reaction treating device
Technical field
The present invention relates to a kind of wastewater treatment equipment, be specifically related to a kind of heterogeneous strengthening for high concentrated organic wastewater and divide and lead circulation anaerobic granular sludge reaction unit, belong to technical field of sewage.
Background technology
Along with industrial boom, kind and the quantity of waste water rapidly increase, also increasingly extensive and serious to the pollution of water body, threaten the health and safety of the mankind.High concentrated organic wastewater is the one of trade effluent, complicated component, and some is also toxic, more difficult also more important than municipal sewage treatment; The hazardness of the high concentrated organic wastewater that industry produces is mainly reflected in three aspects, one is aerobism harm: due to biological degradation, high concentrated organic wastewater can make receiving water body anoxic even anaerobism, and most aquatic organism is by death, thus generation stench, worsen water quality and environment; Two is organoleptic pollutions: high concentrated organic wastewater not only makes water body lose use value, more has a strong impact on the orthobiosis of the nearby water bodies people; Three is causing toxicity harm: containing a large amount of toxic organic compound in ultra-high concentration organic wastewater, constantly can accumulate, store, finally enter human body, be detrimental to health in the physical environment such as water body, soil.
Technology of High Concentration OrganicWastewater Treatment is divided into roughly 3 classes: materializing strategy technology, chemical treatment method and biologic treating technique, specific as follows:
(1) materializing strategy technology: a kind of pretreated means of physico-chemical process Chang Zuowei are applied to treatment of Organic Wastewater, pretreated object is the useful component by reclaiming in waste water, or some difficult for biological degradation things are processed, thus reach organics removal, improve biochemical, reduce biochemical treatment load, improve processing efficiency.General conventional physico-chemical process has extraction process, absorption method, method of enrichment etc.Extraction process is simple, is suitable for the organism processing recovery value, but can only be used for nonpolar organic matter, and the organism be extracted and the waste water after extracting need process further, and organic solvent also may cause secondary pollution.Extraction is the physical transfer process of a pollutent, and the degraded of really.The sorbent material that absorption method is commonly used in organic waste water has gac and macroporous resin, although gac has higher adsorptivity, owing to regenerating difficulty, costly and at home less use.Method of enrichment is simple to operate, technical maturity, and can realize the partially recycled of useful matter, is suitable for processing treating high-concentration saline organic wastewater, and the shortcoming of this method is that energy consumption is high.
(2) chemical treatment method :chemical treatment method is that the pollutant component in waste water is converted into innoxious substance by applied chemistry principle and chemical action, makes the method that waste water is purified.Chemical oxidization method is divided into two large classes, and a class utilizes strong oxidizer (as hydrogen peroxide, potassium permanganate, hypochlorite, ozone etc.) that the oxidation operation in waste water is become carbonic acid gas and water at normal temperatures and pressures; Another kind of is organism in Decomposition Wastewater at high temperature under high pressure, and comprise supercritical water oxidation and wet-air oxidation technique, oxygenant used is generally oxygen or hydrogen peroxide, and the general catalyzer that adopts reduces reaction conditions, accelerates speed of reaction; Chemical oxidization method speed of response is fast, control is simple, but cost is higher, is usually difficult to by the organism oxidation step of difficult degradation to inorganic substance, and less to the research of the control of intermediate product at present.This technology also usually uses as the pretreatment process of biochemical treatment.Its main method has burning method, Fenton oxidation method, Ozonation, electrochemical oxidation process etc.
(3) biologic treating technique: biological treatment is the main technique of purification of waste water, mainly for the treatment of the organic waste water of the industries such as agricultural chemicals, printing and dyeing, pharmacy.Biological treatment is the biotechnology utilizing the metabolism of microorganism to decompose, transform toxic and harmful substance in water body and other various component that exceeds standard, the place of Degradation is mainly containing microbic activity mud, microbial film and corresponding reactor thereof, and be born different kind organism treatment technology thus.Microbial method is economy, safety not only, and the pollutent threshold value of process is low, residual less, non-secondary pollution, has good application prospect.According to the difference of reaction conditions, microorganism treatment can be divided into Aerobic biological process and the large class of anaerobic biological treatment two.The change of Aerobic biological process to waste water quality, the water yield has stronger adaptability, better to the organic matter removal effect in waste water, but Aerobic biological process needs aeration oxygen supply, and energy consumption is larger, in being applicable to, the process of low-concentration organic waste water, for high concentration organic sewage, there is intractability.Anaerobic biological treatment is a kind of sewage disposal technology with very large application prospect, especially in high concentration wastewater treatment field.Under many circumstances, anaerobic technique is the first-selected technique of the wastewater treatment under process high loading, subsidence volumn limited circumstances.Relative to Aerobic biological process method, anaerobic technique does not need separately to add oxygen source, and working cost is low, and surplus sludge volume is few, and organic loading is high.Its main drawback is that speed of response is slower, reaction times is longer, process structures volume is large, the cycle that starts is long, the scarce capacity for the treatment of S S, be difficult to form granule sludge etc. during process high-concentration waste water, but these methods of the prior art are difficult to process to high concentrated organic wastewater, and the treatment time is long, be difficult to form granule sludge, therefore, a kind of new technical scheme of exigence solves the technical problem existed in prior art.
