Description

A kind of aerobic fluidized bed-the biological filter coupled reactor
Technical field
The utility model relate to a kind of aerobic fluidized bed-the biological filter coupled reactor, belong to environmental engineering and technology for treating industrial waste water field, be applicable to and handle high NH 3-N, the industry of high COD and sanitary wastewater can efficiently be removed COD and efficient denitrification, save energy.
Background technology
Along with the development of society and the raising of people's living standard, environmental problem has obtained people's extensive concern gradually, and owing to the aggravation of environmental pollution, country and various circles of society more and more pay attention to the improvement of environment in recent years.Sewage disposal particularly receives publicity as the important component part of environmental improvement, and treatment technology has also obtained very fast development.
Early 1970s, the aggravation of energy dilemma and becoming increasingly conspicuous of global environment problem in the world wide, and interdisciplinary mutual intersection has promoted deepening continuously of sewage disposal technology research.Bioremediation is all to have obtained breakthrough in theory or in concrete application facet as the main method of sewage disposal, and reactor becomes one of field wherein with fastest developing speed.
Biological fluidized bed is a kind of novel wastewater treatment equipment that occurred in recent years, whether according to the needs aeration can be divided into aerobic biological fluid-bed and two types of anaerobe fluidized-beds, can be divided into two types of outer circulation biological fluidized bed and inner loop fluidized bed reactors according to Recycle design, wherein the guide shell of inner loop fluidized bed reactor can be divided into again one with many, one-level and multistage etc. multi-form.
The organism fluidization bed technique is a kind of novel bio membrane process, grows up in early 1970s after the chemical field widespread use continue fluidization.Its carrier is fluidized state in fluidized-bed, makes between solid (microbial film), liquid (waste water), gas (air) 3 phases fully to be contacted, and sharp impacts between the particle, biofilm surface is brought in constant renewal in, and microorganism is in the vigorous stage of growth all the time.This technology makes the biomass that keeps high density in the reaction zone, mass-transfer efficiency is high, thereby make the substrate degradation speed of waste water fast, hydraulic detention time is short, operating load is higher 5~10 times than general activated sludge process, the anti impulsion load ability is strong, and in addition, biological fluidized bed also has advantages such as floor space is little.
The biological filter be beginning of the nineties late 1980s in Micro-polluted Water on the filtering basis, use for reference the thought of saprobia catalytic oxidation treatment process and a kind of sewage treatment technique of producing.Greatly, easily distribute shortcomings such as foul smell and fluctuation of service and receive much concern owing to it has overcome the activated sludge process floor space.Its principle of work is, in the filter tank, load the less particulate filter of a certain amount of particle diameter, filter material surface and filtrate internal capillary growth microbial film, the inner aeration in filter tank, effluent stream through the time, utilize on the filtrate the strong oxidative degradation ability of high-concentration biological amount that sewage is carried out fast purification, this is the oxidation degradation process; Simultaneously, effluent stream is out-of-date, utilizes particle diameter of filter medium features of smaller and biomembranous biological flocculation, holds back a large amount of suspended substances in the sewage, and guarantees that the microbial film that comes off can not drift out with water, and this is for holding back adsorption.
The biological filter has more advantage: (a) adopt the small size particle filler as filtration medium and bio-carrier, and organism volumetric loading height, floor space is little, and structure of reactor is simple, and operational management is convenient.(b) bring into play biological oxidation, biofloculation, absorption and physics crown_interception synchronously, the biophase complexity is various, the processing efficiency height.(c) the granular filler bed accessory has higher oxygen transfer efficiency, adopts low aeration rate promptly can reach the oxygen supply requirement, and operation energy consumption is lower.(d) have high processing efficient, can tolerate higher organic loading, nitrification and denitrification efficient height.(e) have tangible spatial gradient feature in the reactor, different pollutents can be removed gradually at unified reactor.
Make a general survey of documents and materials both domestic and external, common aerobic sewage-treating reactor mainly contains 7 parts and forms: water inlet system, aerating system, reaction zone, triphase separator, outlet system, sludge drainage system and gas gathering system.(a) water inlet system generally is located at reactor lower part, its function is that waste water is assigned in the whole reactor, allow the interior microbe stuffing of waste water and reactor fully contact, make the microorganism in the reactor fully obtain nutrition, improve the utilization ratio of reactor volume, simultaneously, water inlet system also has agitating function.(b) aerating system mainly is responsible for gas is provided in reactor, makes the oxygen level in the reactor maintain certain level, thereby makes the microorganism in the reactor keep greater activity.(c) reaction zone is the core of whole reactor, and it is the zone of enriched microorganism filler, and waste water here contacts with microbe stuffing, produces the intensive oxidizing reaction, and organism is decomposed by aerobic bacteria.(d) effect of triphase separator is that the gas, liquid, solid three-phase is effectively separated.(e) effect of outlet system is to make the waste water after the processing discharge reactor, and processed waste water collected is used for refluxing or discharging.(f) effect of sludge drainage system is the excess sludge that regularly discharges in the reactor; (g) effect of gas gathering system is to collect the biogas that produces in the reactor, analyzes its content and composition, for the running status of debugging reactor provides foundation.
At present, based on biological fluidized bed, biological filter more advantage is arranged, its correlative study is more, still, when use separately biological fluidized bed and biological filter, also has some shortcomings, such as, the biological fluidized bed energy consumption is big, the easy obstruction of BAF etc.
