Sewage treater containing solid impurity

Abstract

The invention is a device for purifying various production and domestic sewage containing only solid impurities. According to the technical scheme provided by the invention, a collection area for solid impurities is provided at the bottom of the cylindrical settling device, a discharge port is provided on the collecting area, and a main settling area connected with the collecting area is provided in the middle of the cylindrical settling device. The inner wall of the main settlement area is provided with a number of vertical stable partitions, and the upper part of the cylindrical settlement device is provided with an overflow settlement area, and a number of overflow tanks are set in the overflow settlement area. There is a connecting pipe connecting adjacent overflow tanks, the connecting pipe is connected with the liquid discharge port arranged on the outer wall of the overflow settlement area, the inlet end of the liquid inlet pipe is connected with the external sewage pipe, and the outlet of the liquid inlet pipe The end is inserted in the main settlement area. The invention has the advantages of small floor area, low investment and construction cost, reasonable sewage treatment, simple operation and no need for external mechanical cleaning, and can clean solid impurities and oil stains in sewage.

Description

technical field [0001] The present invention is a kind of sewage treatment equipment, specifically a kind of equipment for purification treatment of production and domestic sewage, which is suitable for the purification treatment of all kinds of sewage containing only solid impurities. Background technique [0002] The existing methods for treating sewage with solid impurities are single, and are mainly supported by various types of sedimentation tanks (concentration tanks, etc.). [0003] The existing various sedimentation tanks have the following problems: firstly, they occupy a large area and have high construction costs, which are not suitable for small-scale production enterprises to carry out large-scale sewage treatment; secondly, the treatment of sediments is more complicated and occupies a large area , can not be processed reasonably in time; the third is that the (concentration pool, etc.) operation is complicated, and mechanical equipment is required to clean up c...
