Sewage treatment device and sewage treatment method beneficial to rapid dissolution of sprinkled materials

Abstract

The invention relates to the field of sewage treatment, in particular to a sewage treatment device and method beneficial to rapid dissolution of sprinkled materials. The sewage treatment device comprises a water treatment compartment, a feeding cavity, a reaction cavity and a precipitation cavity are formed in the water treatment compartment, the feeding cavity is divided into a feeding space anda conveying space, and the conveying space is integrally designed to be of an inverted-bucket-shaped structure; the diameter of an inner cavity of the conveying space is gradually decreased, a water conveying net plate is arranged at the bottom of the conveying space, a plurality of water conveying holes are formed in the water conveying net plate, a spiral track groove is formed in the inner wallof the conveying space, and a center line pipe shaft is installed in the feeding cavity and installed in the water treatment compartment through a supporting bearing. The center line pipe shaft is ofan inner hollow structure and comprises a stirring section, an outer edge section and a material conveying section. Vortex water flowing in a clockwise rotating mode or an anticlockwise rotating modeis formed in the conveying space, and then the mixing effect of sewage and a flocculating agent is accelerated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device and method that facilitate the rapid dissolution of sprinkles. Background technique [0002] In the process of sewage treatment, it is necessary to carry out coagulation treatment on sewage. Coagulation refers to the aggregation process of colloidal particles and tiny suspended solids in water. The coagulation process is to add chemicals in the process of sewage treatment to make impurities coagulate and flocculate. In the coagulation process, the substance that can flocculate and coagulate is called a coagulant. The coagulant is mainly used for the purification of drinking water, the treatment of industrial wastewater and special water quality, but in the existing sewage treatment process, The coagulant is dissolved manually, which is time-consuming and labor-intensive, the stirring is uneven, the dissolution effect is poor, and it is not condu...

[0002] In the process of sewage treatment, it is necessary to carry out coagulation treatment on sewage. Coagulation refers to the aggregation process of colloidal particles and tiny suspended solids in water. The coagulation process is to add chemicals in the process of sewage treatment to make impurities coagulate and flocculate. In the coagulation process, the substance that can flocculate and coagulate is called a coagulant. The coagulant is mainly used for the purification of drinking water, the treatment of industrial wastewater and special water quality, but in the existing sewage treatment process, The coagulant is dissolved manually, which is time-consuming and labor-intensive, the stirring is uneven, the dissolution effect is poor, and it is not conducive to the coagulation and flocculation of impurities in the sewage, resulting in poor sewage treatment effect, which is not conducive to the development and implementation of sewage treatment. Not conducive to people's production and life

[0003] Chinese patent (authorized announcement number: CN108940006A) discloses a coagulant dissolving device for sewage treatment, which can evenly dissolve the coagulant, can carry out three-dimensional uniform stirring, and is beneficial to the coagulation and flocculation of impurities in sewage; but There are great defects in the actual operation of this patent. The patent is still operated by a single mixing device in essence, and the operation method and technical effect are very limited.
