Domestic sewage treatment device based on water treatment agent and ceramic membrane

Abstract

The invention discloses a domestic sewage treatment device based on a water treatment agent and a ceramic membrane, which is applied to the technical field of sewage treatment equipment. The key points of the technical scheme are as follows: the device comprises a mixing chamber; a water inlet and a liquid inlet are respectively formed in the two ends of the top side of the mixing chamber; one side of the water inlet is communicated with a sewage chamber through a water conveying pipe; a cover plate is hinged to the top end of the sewage chamber; the inner wall of the sewage chamber is detachably connected with a first filter screen; a sliding groove is formed in the sewage chamber in the direction close to the opening; sliding plates matched with the sliding groove are fixedly arranged atthe two ends of the first filter screen; a first control valve used for controlling the sewage flow is arranged on the water conveying pipe; and one side of the liquid inlet is communicated with a water treatment box through a liquid conveying pipe, and a liquid inlet cavity is formed in the water treatment box. The domestic sewage treatment device has the technical effect that a stirring ring can better stir a mixture of sewage and a water treatment agent, so that the sewage and the water treatment agent are more fully mixed, and the sewage treatment effect is better.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a domestic sewage treatment device based on a water treatment agent and a ceramic membrane. Background technique [0002] Domestic sewage is the wastewater discharged from residents' daily life, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses, etc.). The organic matter present in domestic sewage is extremely unstable and easily rots to produce stench. Bacteria and pathogens reproduce in large numbers using organic matter in domestic sewage as nutrients, which can lead to the spread of infectious diseases. ...
