Sewage purification device

Abstract

The invention provides a sewage purification device. The sewage purification device comprises a primary purification box and a refined-grade purification box which are communicated through at least one pipe. The primary purification box is divided by first grids into a primary buffering chamber, a first primary purification chamber and a second primary purification chamber, wherein the primary buffering chamber, the first primary purification chamber and the second primary purification chamber are communicated, and the first primary purification chamber and the second primary purification chamber are provided with filter elements; the primary buffering chamber is communicated with a water inlet, and the filter elements are connected with the inner wall of the first primary purification chamber and the inner wall of the second primary purification chamber in a sealed-sliding mode respectively; the refined-grade purification box is divided by second grids into a first refined-grade purification chamber, a second refined-grade purification chamber and a third refined-grade purification chamber, wherein the first refined-grade purification chamber, the second refined-grade purification chamber and the third refined-grade purification chamber are spaced through refined-grade buffering chambers; the refined-grade buffering chambers are communicated with a water outlet, and refined-grade filter elements are arranged in the first refined-grade purification chamber, the second refined-grade purification chamber and the third refined-grade purification chamber respectively, and are connected with the inner wall of the first refined-grade purification chamber, the inner wall of the second refined-grade purification chamber and the inner wall of the third refined-grade purification chamber in a sealed-sliding mode respectively. By means of the sewage purification device in the technical scheme, domestic sewage can be subjected to stage treatment, the purification degree is high, and application occasions of purified sewage can be expanded.

Description

technical field [0001] The invention relates to a sewage purification device, which belongs to the technical field of sewage treatment and environmental protection. Background technique [0002] 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, etc., while domestic sewage is sewage produced in daily life, which refers to a complex mixture of various forms of inorganic and organic substances, including: ①floating and suspended solid particles of large and small sizes; ②glue and gel-like diffusers; ③ pure solution, how to remove these pollutants in water has become the key to sewage purification. [0003] Traditional domestic sewage treatment is mostly primary treatment, which can only filter certain types of impurities in sewage, the degree of purification is not high, and the application ...
