Abstract

The invention relates to an efficient solid-liquid separation device for sewage. The device comprises a box body, a water inlet system is arranged on one side of the box body, a water outlet system isarranged on the other side of the box body, a filtering system is obliquely arranged in the box body, the lower end of the filtering system is located on the side of the water inlet system, the higher end of the filtering system is located on the side of the water outlet system, and a spiral filter pressing system is cooperatively arranged at the higher end of the filtering system. According to the solid-liquid separation device, a traditional physical treatment mode for sewage can be simplified, traditional physical treatment units are integrated, the technological process is shortened, particles difficult to settle and fine sand particles are removed, sludge concentration and dehydration processes can be synchronously achieved, and the solid-liquid separation device provided by the invention is efficient, safe and intelligent, saves energy, and has a small occupied area.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a high-efficiency sewage solid-liquid separation device. Background technique [0002] Urban sewage treatment can be divided into physical treatment, chemical treatment and biological treatment according to the principle of action. Physical treatment method: separate and recover insoluble pollutants in floating / suspended state through physical action; chemical treatment method: remove dissolved and colloidal pollutants through chemical reaction; biological treatment method: remove Organic matter in solution, colloid and fine floating / suspension state. [0003] At present, coarse screens, fine screens, and (aeration) grit chambers are generally used in sewage physical treatment methods to remove impurities with large specific gravity and particle size in sewage, as well as organic matter on the surface, so as to protect pipelines, valves and other facil...
