Description
One, affiliated field:
The invention belongs to the biological wastewater treatment field, be specifically related to the principle and the method that adopt biological module system to carry out biological wastewater treatment and system optimization is regulated and control.
Two, technical background:
Long-term puzzlement wastewater treatment in China is mainly investment, working cost, present traditional activated sludge process and the anaerobic-aerobic activated sludge process (A/O that uses, AA/O) and deutero-intermittent activated sludge process (SBR method), integrated activated sludge processing (UNITANK), the BIOLAK method, two-stage method (AB method), biomembrance process, biological contact oxidation process, oxidation ditch process, CASS, ICEAS, technology and efficient anaerobe reactor (UASB such as land treatment system, ABR, EGSB, IC etc.) and BAF, membrane bioreactor, biological fluidized bed, bio-reactors such as displacing force bed bio-reactor, can not select suitable processing unit according to the waste water quality characteristic easily, and biological treatment system is optimized, cause biological treatment system efficient to be difficult to give full play to, waste investment and power consumption etc.
Three, summary of the invention:
At above problem, the invention discloses a kind of organic waste water treatment biological module system and control technique thereof.It specifically is the general character part of extracting various wastewater biological treatment and high-efficient biological reactor, efficient, low consumption that obtains by integrated innovation and the biological module system that various waste water extensively are suitable for, and can in system, regulate according to water quality characteristic, utilize functional microorganism microbial inoculum enhanced biological treating processes each biology modules size and functional microorganism population structure.
Wherein the biological module system that various waste water extensively are suitable for comprises: the easy degradation of organic waste water anaerobic treatment of high density biology modules, organic wastewater with difficult degradation thereby anaerobism or double oxygen biocatalysis decomposing organism module, high-efficiency aerobic are handled biology modules, common aerobic treatment biology modules.In application, can select part of module wherein to be combined into system according to waste water quality.Waste water quality is at first pressed in the selection of biology modules, and high-concentration waste water is selected the anaerobic biological treatment module; The organic wastewater with medium-low concentration of difficult degradation or nitrogen-containing wastewater need the selection of the denitrogenation oxygen biological treatment module of holding concurrently; The nitrated selection high speed aerobe processing module of the organic wastewater with medium-low concentration of readily biodegradable or nitrogen-containing wastewater; Select the slow organism of degradation rate to handle biology modules to lower concentration and the slow waste water of degradation speed.Module is by handling small molecules, oxygen biological denitrificaion, the aerobic removal of high speed COD, dephosphorization and the difficult degradation lower concentration aerobe processing sequence arrangement at a slow speed of holding concurrently that difficult degradation macromole biocatalysis is degraded to readily biodegradable among the present invention.The selection of microorganism is the water quality composition according to waste water among the present invention, determines principal pollutant, is that substrate and applied envrionment conditions (anaerobism, the oxygen, aerobic of holding concurrently) are selected the commodity microbiobacterial agent by principal pollutant, and considers to be coupled the metabolism relation.
The present invention can need realize the adjusting of each biology modules size, subregion and structure according to the waste water quality characteristic according to wastewater treatment in biological treatment system, application function microbiobacterial agent and bio-immobilized technology are strengthened the treatment efficiency of each biology modules, the microbial species group structure of biological module system is monitored and regulate and control by molecular ecology, make it to give full play to the effect of microorganism and provide optimum environment for its growth metabolism, keep microbic activity and maximum biomass, reach the purpose of best purification pollutent.The anaerobic biological treatment module is mainly high-concentration waste water is decomposed into methane and water by anaerobic biological treatment with organism, and energy consumption is low; The existing denitrification denitrogenation of oxygen deoxidation denitrification module of holding concurrently has the removal partial organic substances again; High-efficiency aerobic biological treatment module has the function of COD degraded, and the nitrated function of ammonia nitrogen is arranged again; The slow organism of degradation rate is handled biology modules and is primarily aimed at installations and facilities fast, and is difficult to handle at high efficiency reactor at some pollutents, and construction unit carries out the module subregion according to the pollutant reaction principle of dynamics.
Microbe carrier, microbiobacterial agent, treatment process and reactor can be realized subregion and combination at a big purification tank for liquid waste, between treating pond and module, leave a gap, put into water in the gap, adopt the interior exterior-applied liquid medicine position of subregion principle for balance in the pond, satisfying under the indeformable condition of each module, save material as far as possible, the collapsible form of each block size available partition is adjusted, according to the head loss of each biology modules water inlet is pressurizeed again, to satisfy the needs that Waste Water Treatment is optimized, determine the biology modules combination.
The present invention can be achieved in the following manner: 1. according to the water quality and the processing feature of waste water, determine its biodegradability and pollutent biochemical reaction kinetics or the degradation kinetics that obtains of chamber lab scale by experiment, determine the composition of biology modules; 2. with collapsible form treating pond is carried out subregion according to selected module; 3. calculate by hydromeehanics and determine each module head loss and make hydraulic gradient drop to minimum by system optimization; 4. by selected biology modules character, determine the adjusting device and the instrument of the required microorganism optimal growth condition that provides; 5. each inside modules adds microbe carrier; 6. each module adds microbiobacterial agent, by bio-immobilized technology functional microorganism is fixed on the carrier; 7. wastewater treatment process is by control dissolved oxygen, temperature, pH, basicity, nitrogen, phosphorus etc., and by each biology modules microbial population of treatment system and quantity are monitored, and from external means (as changing external environment condition, add some microbiobacterial agents etc.) regulate and control, reach the purpose of optimizing Waste Water Treatment.
Use waste water treatment engineering construction investment of the present invention than conventional art equipment economize 35% approximately, working cost than conventional art equipment economize 20% approximately, floor space economizes 80% approximately, can economize 30% approximately by loss-rate conventional art equipment than conventional art equipment.
The present invention has the following advantages:
1, wide adaptability, occupation of land province, reduced investment, running cost is low, excess sludge is few, anti impulsion load, easy to operate and stable, easy to utilize.
2, to strengthening municipal effluent denitrogenation, phosphorus removal functional, novel materialization-integrated realization of biological treatment had distinguishing feature to the aspects such as processing of high density poisonous and harmful organic wastewater with difficult degradation thereby by functional module.
