Description

Domestic sewage treatment equipment Technical Field The utility model belongs to the technical field of sewage treatment equipment, and particularly relates to domestic sewage treatment equipment. Background The sewage treatment is a process of purifying sewage by physical, chemical, biological and other methods to ensure that the sewage reaches a certain water quality standard, so that the sewage can be reused or safely discharged into natural environment. The main purpose of sewage treatment is to remove pollutants, pathogens, harmful substances and the like in sewage, and reduce the harm to the environment and human health. In the existing sewage treatment, suspended solids, colloid particles, organic matters and nutrient substances in the sewage are removed by adding a flocculating agent, so that the sewage treatment efficiency and the water quality are improved. The flocculant promotes the aggregation of suspended particles and colloid particles in water to form a process of larger particles, and a certain action time is needed, however, the conventional sewage treatment equipment is usually continuously added at a constant speed when the flocculant is added, so that excessive addition of the flocculant is easily caused, the medicament is wasted, and the floccules are possibly too loose to influence the precipitation or filtering effect.
