Product Details

Overview:
Residential sewage treatment is different from urban sewage (often including some industrial wastewater) and belongs to the category of domestic sewage treatment. Its water quality and quantity characteristics can be summarized as follows: large changes in water quality and quantity, low concentration of pollutants, lower than urban sewage, good biodegradability of sewage, and low treatment difficulty.
Handling method:
The treatment process of residential sewage treatment equipment varies depending on the function of the sewage discharged into the water body. Common treatment methods include septic tank, primary treatment (initial sedimentation tank), biological secondary treatment, and disinfection and reuse after secondary treatment. Due to the small amount of sewage treatment in the community and low management level, it is recommended to choose sludge free or less sludge treatment processes as much as possible in process design to prevent secondary pollution caused by poor sludge treatment.
technological process:
Process (1):

Wastewater → regulating tank → primary sedimentation tank → biological contact oxidation tank → secondary sedimentation tank → effluent. Biological contact oxidation is a widely used method with the main advantages of short residence time and easy film formation, especially suitable for equipment construction. It is highly favored by environmental protection companies and users for buried construction. However, due to maintenance management and equipment anti-corrosion issues, its application has been limited in recent years. But if the underground reinforced concrete form is built and personnel passages are set up for maintenance, this underground construction method has a large market in community water treatment. However, this method generally has a small treatment scale and is ideal for communities with a daily sewage discharge of less than a few hundred tons. For the treatment of thousands of tons of residential sewage, it is recommended to use buried methods. For the biological treatment part, contact oxidation or CASS process can be used. It is recommended to use low-noise fans or underwater aerators for aeration.
