The high-concentration wastewater has the characteristics that: 1. the concentration of organic matters is high, the COD is higher even reaching tens of thousands to hundreds of thousands mg/L, and the ratio of BOD to COD of the wastewater is less than 0.3. 2. The composition is complex, contains toxic substances, and contains sulfides, nitrides, heavy metals and toxic organic substances. 3. Has peculiar smell and high chroma. 4. The acid-base property is strong.
The biochemical sludge refers to activated sludge in an activated sludge system discharged from a secondary sedimentation tank (or a sedimentation zone) outside the system. In the biochemical treatment process of wastewater, microorganisms in the activated sludge continuously consume organic substances in the wastewater, one part of the consumed organic substances are oxidized to provide energy required by the life activities of the microorganisms, and the other part of the consumed organic substances are utilized by the microorganisms to synthesize new cytoplasm, so that the microorganisms multiply and reproduce to generate the biochemical sludge. The method is mainly used for treating urban domestic sewage by an activated sludge process in China, the amount of sludge generated by sewage treatment plants in China is about 30 ten thousand tons every year, the sludge is increased by 10 percent every year, and a large amount of sludge is not effectively and reasonably treated, so that the environmental pollution is caused.

The method firstly dehydrates the sludge, then carries out thermal hydrolysis, and finally removes COD from the high-concentration wastewater by cooperating with a high-efficiency IC reactor. Chinese patent publication No. CN 109574202A provides a biochemical sludge zero emission approach system, which is a method for making sludge in a secondary sedimentation tank pass through a sedimentation tank, an ozone reaction tower, an aeration tank A and an aeration tank B; after multiple oxidation and bacteria-adding digestion cycles, the sludge in the whole treatment system reaches zero emission. The method mainly reduces the sludge by ozone and adding strains, has the defects of high power consumption due to the addition of ozone, increased sludge yield due to the supplemented strains and difficult stable operation of the system.
