Sewage purifying tank

Abstract

The invention relates to the technical field of sewage purification treatment, in particular to a sewage purification tank. The sewage purification box includes a box body, a water inlet pipe arranged on the top of the box body, a water outlet pipe arranged on the lower side of the box body, and a recovery box located outside the box body. It is characterized in that: the inside of the box body is provided with a guide , the deflector is evenly provided with a number of tapered diversion holes, the box is also provided with a drug injection pipeline and a drug infiltration pipeline connected with the injection pipeline, and the drug infiltration pipeline is arranged at In the inside of the box, the drug seepage pipeline is provided with a plurality of drug outlet holes, which are located between the deflector and the drug seepage pipeline. On the side wall of the box body, there are sewage outlet I and sewage outlet II, which are connected with the sewage outlet. The first pipeline communicating with I and the second pipeline communicating with sewage outlet II are respectively connected to the recovery box, and a filtering device is also provided on the box body between the deflector and the drug seeping pipeline. The sewage purification box designed by the invention has a simple structure, does not need to be disassembled when cleaning the filter screen, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of sewage purification treatment, in particular to a sewage purification tank. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. From the viewpoint of the source of sewage, sewage can be defined as waste-carrying liquid or water discharged from residential, institutional, commercial or industrial areas mixed with groundwater, surface water, snowstorms, etc. There are many types of sewage, and correspondingly there are many technologies and processes to reduce the impact of sewage on the environment. According to the source of sewage, sewage can be divided into these four categories: industrial wastewater from manufacturing, mining a...

At present, the most used sewage treatment equipment is the sewage purification box. In the existing purification box, the sediment in the sewage generally accumulates directly at the bottom of the purification box, and at the same time causes the blockage of the sewage outlet. Some metal ions cannot settle, affecting the settlement effect of sewage

The patent with the application number CN201620102183.2 discloses a sewage purification tank. The sewage entering from the water inlet pipe enters the filter cover through the diversion cover, and then the impurities of the sewage are left in the filter cover under the action of the filter bar net. In order to avoid clogging and improve the purification effect of sewage, the filter cover needs to be cleaned regularly, and the filter cover needs to be disassembled from the fixing plate every time it is cleaned, which is troublesome to use. Simple, easy-to-use sewage purification tank
