Description
Technical field
The present invention relates to a kind of culture device and method of sewage disposal microorganism species, specifically a kind ofly cultivate and store the Apparatus and method for of the active flora of sewage disposal.
Background technology
In the treating processes of organic sewage, biological activated sludge method is high and be used widely to effective removal of pollutent because of it, biological activated sludge method is the method processed organic sewage according to the dominant microflora that the classification selection of source of pollution is applicable, it is strong to organic adsorption and oxidation ability, and processing efficiency is high.
In the mud that biological activity bacterial classification is present in settling tank with spore shape and sewage, the culture cycle that dominant activity mud flora needs several days or tens days is converted into by spore shape, because the active flora of turning out also exists certain life cycle, therefore before this generation active flora life cycle terminates, active flora of new generation must be stored.Although the microbe species in clarifier sludge and quantity a lot, but very most thalline is in inactivation or low activity state, these microorganisms often need certain culture cycle to make it activate after being back to biochemistry pool, can organism in efficient degradation sewage.Therefore want to improve microorganism just must ensure high reactivity flora in mud quantity and accounting to the treatment effect of organic sewage.
Often there is the problem of fluctuation of service in current biological process active sludge water treatment system, namely when the source of pollution speciality in sewage changes, the dominant activity flora be suitable for can not be called in time participates in degraded biochemical reaction, the dominant activity flora source be not suitable for even for the moment, this will inevitably cause Sewage treatment systems processing power decline in a certain amount of time, thus makes the water quality of discharging cannot continue to keep up to standard.Existing solution directly in biochemistry pool, adds carbon source to accelerate the active rate of microorganism species, but the method has also increased the weight of the organic loading of Sewage treatment systems simultaneously, the direct disposition affecting technique, causes effluent quality big ups and downs, causes the consequence that water outlet is not up to standard.
Summary of the invention
