Sewage treatment equipment

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to sewage treatment equipment. The sewage treatment equipment sequentially comprises a settling pond, a coagulation pond, a filtering pond and a disinfecting pond which are communicated with one anther; a crude filtering layer, a fine filtering layer and a re-filtering layer are arranged in the filtering pond sequentially from top to bottom; the disinfecting pond comprises a supporting frame, a water purifying barrel, an air-blowing mechanism and a power mechanism for enabling the water purifying barrelto rotate; a plurality of water buckets are arranged in the water purifying barrel; the water buckets are connected with the inner wall of the water purifying barrel to form a water bucket ring; the air-blowing mechanism comprises an air-blowing pipe and a water wheel; a gas inlet is formed in one end of the air-blowing pipe; the other end of the air-blowing pipe stretches into the water purifyingbarrel; the air-blowing pipe is rotatably connected with the water purifying barrel; the center line of the air-blowing pipe is superposed with the center line of the water purifying barrel; a plurality of air-blowing holes are formed in the air-blowing pipe; and when the water purifying barrel rotates positively, the water wheel rotates reversely under the power action of the water flowing out of the bucket. According to the scheme, the contact area of chlorine and water can be increased, the chlorine and the water are mixed completely and the water purifying effect is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to sewage treatment equipment. Background technique [0002] As we all know, natural precipitation and lake and river water cannot be used for direct drinking or production. Due to various natural and human factors, these waters will contain various impurities, and direct drinking will cause great harm to human health. harm, so countries have thought of treating and disinfecting water. [0003] From the perspective of water supply treatment, impurities in water can be divided into three categories: suspended solids, colloids, and dissolved solids. The purpose of water purification treatment in urban water plants is to remove suspended matter, colloidal matter, bacteria and other harmful components in the raw water that will harm human health and industrial production, so that the purified water can meet the needs of domestic drinking and industrial production. ...

AI Technical Summary

Problems solved by technology

This kind of disinfection equipment has certain defects: the disinfection tank is just a simple container, after the chlorine gas is introduced into the still water, the chlorine gas and the water in the disinfection tank cannot be fully mixed, and the water purification effect is not good
