An automatic sewage treatment tank

Abstract

The present invention relates to the technical field of sewage treatment, in particular to an automatic sewage treatment tank, comprising a tank body, a flocculation liquid addition pipe and a sewage inlet pipe connected to the inner cavity of the tank body are arranged on one side of the upper end of the tank body, the tank body One side of the lower end of the body is provided with a sewage outlet pipe communicating with the inner cavity of the tank; the upper end of the inner wall of the tank is fixed with a horizontally arranged annular plate, and an inner cylinder with an open upper end is arranged inside the annular plate, and the upper end of the inner cylinder is set There is a flange lapped on the annular plate, and the lower end of the inner cylinder is provided with a discharge port; through the setting of the auxiliary stirring rod and the third spring, the auxiliary stirring rod can overcome the spring and swing outward under the action of centrifugal force, so the The attitude of the auxiliary stirring rod is different when the speed is different, so it can fully stir the sewage, increase the effect of flocculation, improve the efficiency of flocculation, and thus meet the expected water quality requirements.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an automatic sewage treatment tank. Background technique [0002] With the rapid development of social economy, the ecological environment has also been damaged, and the pollution and eutrophication of natural water bodies have become increasingly serious, especially in small towns and rural areas in some remote areas. Due to the scattered residences in the villages, domestic sewage is not easy to be treated centrally. The sewage of most houses and farmers is directly discharged without any treatment or simply treated in septic tanks, which makes the natural environment worse. The pollution of domestic sewage in small towns and rural areas has become an important problem that must be solved in environmental protection. Therefore, Methods for domestic sewage treatment in small towns and rural areas have been introduced. [0003] The existing sewage contains a large amoun...
