Domestic sewage treatment apparatus

Abstract

The invention discloses a domestic sewage treatment apparatus. The apparatus comprises a base; the upper side wall of the base is fixedly connected with a fermentation device; the fermentation devicecomprises a fermentation tank; and a fermentation cavity is formed in the fermentation tank. According to the invention, when a first motor drives a driving wheel to rotate, a water inlet pipe is driven to rotate, so that two conical funnels are driven to rotate. Due to the action of centrifugal force, a liquid in sewage in a separation cavity can be thrown out onto the side wall of a treatment cavity and into a collecting groove of a collecting plate through separation holes in the side wall of the separation cavity, and meanwhile, sundries can slide downwards along the side wall of the separation cavity under the gravity action of the sundries. A second motor drives a stirring shaft to rotate through an output shaft, and the sundries are crushed more thoroughly, so that fermented sundries are changed into a natural organic fertilizer, and can be used for fertilizing crops in a field. The eutrophication of a water body caused by the fact that the filtered sewage liquid flows into a river is avoided, so that the influence to water ecology balance is avoided.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment, in particular to a domestic sewage treatment device. Background technique

[0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Various fields are also increasingly entering the daily life of ordinary people;

[0003] Most of the existing domestic sewage treatment devices discharge the treated sewage directly. The discharged sewage contains a large amount of organic matter such as: vegetable leaves, noodles, rice, etc. When the sewage is discharged into the river, it will lead to the enrichment of the water. Nutritization may lead to a large number of algal blooms, thus affecting the balance of water ecology. C...
