Safe and efficient environmental protection treatment device for sewage

Abstract

The invention discloses a safe and efficient environmental protection treatment device for sewage. The device comprises a pretreatment tank, an aeration device, a spray rack pipe, an air bag, a heater, a stirring motor, a gas collecting tank, a stirring impeller and an ionizing rod. The top and side walls of the pretreatment tank are connected to water inlet pipes. The pretreatment tank is communicated with the aeration device. The top of the pretreatment tank is provided with the stirring motor. The heater is installed in the inner wall of the pretreatment tank. The top of the pretreatment tank is communicated with the gas collecting tank through a breather pipe. The side wall of the pretreatment tank is communicated with one end of a water passing pipe. The other end of the water passingpipe is connected to a micro-electrolysis disinfection chamber. The ionizing rod is arranged in the micro-electrolysis disinfection chamber. An ultraviolet sterilization lamp is installed in the micro-electrolysis disinfection chamber. A water outlet end of the micro-electrolysis disinfection chamber is communicated with a reverse osmosis filter tank. A water-stop sheet is arranged in the reverseosmosis filter tank. The bottom end of the water-stop sheet is provided with a reverse osmosis film. The side of the reverse osmosis filter tank is provided with a water outlet pipe. The device improves the efficiency and effect of sewage treatment, improves the environmental protection safety, has a simple structure, realizes a low cost, is easy to use and is conducive to promotion.

Description

technical field [0001] The invention relates to the field of environmental protection treatment, in particular to a safe, efficient and environmental protection treatment equipment for sewage. Background technique [0002] In recent years, the problem of environmental pollution has become more and more serious. Environmental pollution will cause direct damage and impact on the ecosystem, such as desertification and forest destruction, and it will also cause indirect harm to the ecosystem and human society. Sometimes this indirect environmental Effects are more harmful than the immediate harm caused at the time, and are more difficult to undo. For example, the greenhouse effect, acid rain, and ozone depletion are environmental effects derived from air pollution. This kind of environmental effect derived from environmental pollution has a hysteresis and is often not easy to detect or predict when the pollution occurs. However, once it occurs, it means that the environmental p...

Among them, water pollution is an important issue. Water is the source of life. Part of water pollution is domestic sewage. Domestic sewage is mainly various detergents and sewage, garbage, and feces used in urban life. Among them, domestic sewage Phosphorus enrichment oxidation is particularly serious, the existing sewage treatment equipment generally has high cost and consumes a lot of energy, and it is difficult to meet the requirements of small and medium-sized enterprises
