Sewage purifying and using device used for municipal engineering

Abstract

The invention discloses a sewage purifying and using device used for municipal engineering. The sewage purifying and using device used for municipal engineering comprises an aeration and sedimentationtank, a sludge sedimentation box, a sewage disinfection box and a water collection tank, wherein two sets of first gratings are installed in the aeration and sedimentation tank, three sets of removable magnets are installed on the upper surface of each first grating, an aerator is installed in a central position of the top of the aeration and sedimentation tank, an aeration pipe which extends into the aeration and sedimentation tank is installed at an output end of the aerator through a guiding pipe, and the sludge sedimentation box is connected with the side, away from a water inlet pipe, ofthe aeration and sedimentation tank through a first water guiding pipe. According to the sewage purifying and using device used for municipal engineering, by arranging ultraviolet lamps on a top wallof an inner cavity of a disinfection box, sterilization and disinfection effects can be further improved, purified clear water is subjected to more thorough sterilization and disinfection, and is reused, and by arranging the water collection tank and a fourth water suction pump, a water body, which is subjected to a few purifying steps and is still not qualified, can be purified and disinfected continuously, so that optimal water quality is achieved.

Description

technical field [0001] The invention relates to the technical field of municipal sewage treatment equipment, in particular to a sewage purification and utilization device used in municipal engineering. Background technique [0002] In the sewage produced by the municipal engineering industry, there are mainly impurities such as silt, iron, etc. If these waste water are discharged directly, it will pollute the surrounding environment, especially the surrounding water resources and environment. The technical solution of the original sewage treatment plant is to have multiple raw water pools to settle the sewage and then discharge the water. There are many problems in the use of this sewage treatment station. For example, the sewage produced can only be directly treated after simple treatment. Discharge and use will cause pollution to the surrounding environment, and due to the simple purification procedure, the removal of impurities and incomplete water disinfection will resul...

[0002] In the sewage produced by the municipal engineering industry, there are mainly impurities such as silt, iron, etc. If these waste water are discharged directly, it will pollute the surrounding environment, especially the surrounding water resources and environment. The technical solution of the original sewage treatment plant is to have multiple raw water pools to settle the sewage and then discharge the water. There are many problems in the use of this sewage treatment station. For example, the sewage produced can only be directly treated after simple treatment. Discharge and use will cause pollution to the surrounding environment, and due to the simple purification procedure, the removal of impurities and incomplete water disinfection will result in the inability to reuse the purified water resources, which is a great waste of water resources
