Description

[0002] Sewage treatment can be divided into primary treatment, secondary treatment and tertiary treatment according to the degree of treatment.

[0003] The primary treatment is mainly to remove the suspended solid matter in the sewage, and physical methods are often used. The biochemical oxygen demand removal rate of the wastewater after primary treatment is only 20%, which is still not suitable for discharge and needs secondary treatment. The main task of secondary treatment is to significantly remove the organic matter in the colloid and dissolved state in the sewage, and the biochemical oxygen demand removal rate is 80% to 90%. Generally, the sewage after secondary treatment can meet the discharge standards, and the activated sludge method and biofilm treatment method are commonly used. The purpose of tertiary treatment is to further remove certain special pollutants, such as fluorine removal, phosphorus removal, etc., which belongs to deep treatment, and chemical methods are often used.
