MBBR Technology Sewage Treatment Plant Treatment Process

The process of sewage treatment equipment manufacturers varies according to the function of the sewage water body in the community. Commonly used treatments include: septic tank, primary treatment (primary sedimentation tank), secondary biological treatment and reuse after secondary treatment. Due to the small water volume and low level of sewage treatment in the community, the treatment process with no or less sludge should be selected as much as possible in process design to prevent secondary pollution caused by improper sludge treatment. At present, the more commonly used domestic sewage treatment processes are: sewage → regulating tank → primary sedimentation tank → biological oxidation tank → secondary sedimentation tank →, biological oxidation is widely used, the main advantages are short residence time and easy film formation, especially suitable for equipment The underground construction is favored by environmental protection companies and users, but due to problems in maintenance and equipment corrosion, its application has been restricted in recent years. However, if it is built in the form of underground reinforced concrete, and personnel passages are set up for maintenance, this kind of underground construction has a large market in food water treatment, but this kind of general treatment scale is small, and the daily sewage discharge is less than several hundred tons. For the treatment of thousands of tons of food sewage, it is recommended to use ground construction. The biological treatment part can use oxidation, or R or its improved C process. It is recommended to use low-noise fans or underwater aerators for aeration.
