At present, there are many sewage treatment processes adopted at home and abroad, which are mainly divided into activated sludge method and biofilm method. Our common aeration process, oxidation ditch process, A/B process and A2/O process belong to the former, while biological rotary table and contact oxidation process belong to the latter. Integrated sewage treatment equipment is a device that integrates the primary sedimentation tank, I and II contact oxidation tanks, the secondary sedimentation tank and the sludge tank, and carries out blast aeration in the I and II contact oxidation tanks, so that the contact oxidation method and the activated sludge method can be effectively combined, and at the same time, strengths and weaknesses can be avoided, further improving the sewage treatment level. Its outstanding advantages are:
1, strong impact load resistance. The average residence time of contact oxidation method is more than 6 hours;
2. It has the ability to remove nitrogen and phosphorus, and can treat industrial wastewater, domestic sewage and urban sewage by adjusting the equipment structure;
3. The fillers in the contact oxidation tank are mostly combined soft fillers, which have light weight, high strength, stable physical and chemical properties, large specific surface area, strong adhesion of biofilm and high contact efficiency between sewage and biofilm;
4. In the contact oxidation tank, the fiber bundle is blown and aerated by an aerator, so that the fiber bundle floats continuously, the aeration is uniform, and the microorganisms grow mature, which has the characteristics of activated sludge process;
5, the effluent quality is stable, the sludge yield is low, and it is easy to treat; 6. Submersible pump can be installed on the equipment, which reduces the project investment;
7. The equipment can be located on the ground or buried underground. When buried underground, the upper cover can be used for greening, with small factory area and few ground structures;
8, easy to complete automatic control, simple management and operation.
