Background technology
By tradition, single anaerobic process, aerobic method turns to anaerobism to Biological Treatment of High Strength Organic Wastewater in recent years---aerobic combination treatment method, as anaerobism,---aerobic method A/O method, anaerobism---anoxic---aerobic method etc. complete the biological treatment to high concentrated organic wastewater by adopting the multiple combination treatment process.Thus, the aerobic-anaerobic of CN100484891C discloses a kind of organic waste water anaerobism---aerobic circular integration bioremediation and system, the disclosed a kind of microbiological anaerobic that utilizes of CN1413926---aerobic and be satiated with food---hungry double stimuli or the sewage treatment process that micro-oxygen absorbs fast and system etc., all innovate the anaerobic-aerobic treatment process.The organic waste water anaerobic treatment process generally is divided into normal temperature, middle temperature, three kinds of high temperature, because mesophilic microorganism bacterial classification kind is many, and be easy to cultivate domestication, active high, therefore application is more extensive, and anaerobism water inlet and aerobic treatment process temperature are lower than anaeration in normal temperature treatment process temperature, when organic waste water being carried out to the processing of anaerobic-aerobic combination process, in the anaerobic reaction stage, need to heat organic waste water, and the organic waste water after anaeration in normal temperature is processed carries out when aerobic process is processed being lowered the temperature, in actual production process or complex process equipment and need to consume a large amount of energy and carry out temperature regulation to organic waste water, process the inefficiency of organic waste water.
Summary of the invention
The present invention is intended at least solve one of technical problem existed in prior art.For this reason, the present invention proposes a kind of method of anaerobic-aerobic combined treatment organic waste water, comprises the following steps:
A, organic waste water is incorporated in anaerobic reactor, and organic waste water is carried out to preheating, then stop preheating;
B, carry out anaerobic reaction in anaerobic reactor, and the waste water after anaerobic reaction is processed is incorporated into to intermediate pool;
C, to the processing of lowering the temperature of the organic waste water after anaerobic reaction is processed in intermediate pool, and transfer of heat unnecessary in temperature-fall period is heated the organic waste water in anaerobic reactor in anaerobic reactor;
D, the waste water of processing through cooling in intermediate pool is incorporated in aerobic reactor and carries out aerobic reaction.
Further, when preheating, when reaching 32 ° to 38 °, temperature stops preheating.
Further, described cooling is processed and by transfer of heat unnecessary in temperature-fall period to the method to the heating of the organic waste water in anaerobic reactor in anaerobic reactor is, utilize heat pump to be lowered the temperature and transfer of heat, concrete: as to utilize heat pump that thermal medium is compressed into to liquid state and send in the heat exchanger that is arranged on intermediate pool, the heat that the liquid heat medium absorbs organic waste water in intermediate pool is gasificated into high-temperature gas, the high-temperature gas thermal medium is fed in the scatterer be arranged in anaerobic reactor through pipeline, carry out thermal exchange with the low temperature organic waste water in anaerobic reactor, low temperature organic waste water is heated, thereby complete the transfer of heat process.
Further, the temperature that is incorporated into the organic waste water in aerobic reactor is 16 ° to 20 °.
The preferred temperature of processing organic waste water with the anaeration in normal temperature reaction process is 32 ° to 38 °, and the preferred temperature of processing organic waste water with aerobic reaction process is 16 ° to 20 °.Therefore through anaerobic reaction, aerobic reaction combined treatment organic waste water the time, from anaerobic reaction technique, organic waste water out need to be done cooling is processed and carry out aerobic reaction technique again and just can obtain preferably efficiency to shorten the treatment process time.The present invention has utilized the temperature head of anaerobic reaction preferred temperature, aerobic reaction preferred temperature admirably, by setting up intermediate pool, by heat pump, will be lowered the temperature through the organic waste water of anaerobic reaction art breading, and by heat pump, the heat absorbed in its temperature-fall period is turned back in anaerobic reactor simultaneously, removed the energy that in the anaerobic reaction, the organic waste water temperature is improved and need from, compared with prior art, saved widely the energy, meet the reaction conditions of next step technique aerobic reaction technique simultaneously, improved the processing efficiency of organic waste water.
