Abstract

The invention discloses a solid-liquid screening device for sewage pretreatment. The solid-liquid screening device comprises a pretreatment device shell; a water inlet is formed in the top of the pretreatment device shell; a material scraping device is arranged inside the pretreatment device shell; a solid waste collection box is fixedly connected to each of the two sides of the bottom of the inner wall of the pretreatment device shell; a vertical screen is fixedly connected to one side, far away from the pretreatment device shell, of each of the solid waste collection boxes, and the tops of the two vertical screens are fixedly connected through a horizontal screen. The solid-liquid screening device disclosed by the invention has the benefits that through mutual matching of the material scraping device, the solid waste collection boxes, the vertical screens and the horizontal screen, the effect of separating solid from liquid in sewage in advance is realized, and the use effect of sewage treatment equipment is greatly optimized, so that the follow-up sewage treatment work is simpler and more convenient, and the sewage can be more quickly treated; the operation is simple, both time and labor are saved, the working effect is greatly improved, and the treatment effect is more ideal.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a solid-liquid screening device for sewage pretreatment. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. , and more and more into the daily life of ordinary people. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage is sewage generated in daily life, which refers to various forms of inorganic substances and Complex mixtures of organic matter, including floating and suspende...
