The biochemical treatment of wastewater is one of the most important processes in the wastewater treatment system, which is referred to as biochemical treatment. Biochemical treatment is to effectively remove the soluble organic matter and some insoluble organic matter in the waste water and make the water purify. In fact, our biochemical treatment is not very strange, there is a food chain in natural waters, the big fish eat small fish, small fish eat shrimp, shrimp eat insects, insect eating microbes, microbial food wastewater, if not this food chain, nature will be messed up. In natural rivers, has to rely on organic living microorganisms, day and night will they organic oxidation or reduction of the people into the river, eventually transformed into inorganic substances, if I do not have the presence of microorganisms, we surrounding rivers, ranging from several months to more than one or two years, will become smelly river. And just because microorganisms are too small and fragmented, so that our eyes can not see it.
Biochemical wastewater treatment is to strengthen this process in that condition, people will have to count the number of microorganisms are concentrated in a pond, creating a very suitable for microbial propagation, growth environment, microbial proliferation, in order to improve the speed and efficiency of the decomposition of organic matter. Then the sewage is pumped into the pool, so that the organic matter in the waste water can be oxidized and degraded in the process of microorganism's life activities, so that the wastewater can be purified and processed. Compared with other treatment methods, the biochemical method has the characteristics of low energy consumption, no medicine, good treatment effect and low cost of treatment.
