Energy-saving and environment-friendly municipal sewage treatment device

Abstract

The invention discloses an energy-saving and environment-friendly municipal sewage treatment device, which belongs to the technical field of municipal sewage treatment, and comprises a body, a supportframe, a second electric telescopic rod, a sludge discharge chamber, a stirring blade, a biological purification film, a confluence cover and a spiral heat exchange pipe; a support plate is arrangedin the body, and the sludge discharge chamber is arranged above the support plate and between the support plate and the body; a second electric telescopic rod is mounted on the inner wall of the rightside of the sludge discharge chamber, and a sludge pressing plate is mounted on the left side of the second electric telescopic rod; a stirring chamber is arranged below the supporting plate, a motoris installed on the left side of the stirring chamber, and a rotating shaft is installed on the right side of the motor; a purification chamber is arranged on the lower portion of the interior of thebody, a plurality of biological purification films are evenly distributed in the purification chamber, a spiral heat exchange pipe is arranged in the purification chamber, the feeding pipe is connected with the left side of the spiral heat exchange pipe, and the right side of the spiral heat exchange pipe is connected with a discharging pipe. Waste heat of sewage can be recycled through the arranged spiral heat exchange pipe, and more energy is saved and more environment is protected.

Description

technical field [0001] The invention belongs to the technical field of urban sewage treatment, in particular to an energy-saving and environment-friendly urban sewage treatment device. Background technique [0002] Urban sewage treatment is mainly an environmental protection measure to purify and treat urban sewage. The main sources of urban sewage are domestic sewage, industrial sewage and runoff sewage. As the requirements for environmental protection become more and more urgent, urban sewage treatment The problem is getting more and more attention, but for densely populated cities, water pollution has begun to lead to "water crises" to varying degrees. The population of cities is relatively dense, especially for some large cities with large populations. If there is a water pollution problem If the sewage is not treated, it will also lead to the lack of water resources, which will seriously affect people's life and work, restrict the development of many industries, and cau...

[0002] Urban sewage treatment is mainly an environmental protection measure to purify and treat urban sewage. The main sources of urban sewage are domestic sewage, industrial sewage and runoff sewage. As the requirements for environmental protection become more and more urgent, urban sewage treatment The problem is getting more and more attention, but for densely populated cities, water pollution has begun to lead to "water crises" to varying degrees. The population of cities is relatively dense, especially for some large cities with large populations. If there is a water pollution problem If the sewage is not treated, it will also lead to the lack of water resources, which will seriously affect people's life and work, restrict the development of many industries, and cause unbearable Estimated direct and indirect economic losses

[0003] The treatment process is different for different types of urban sewage. During the treatment process of existing urban sewage, most of them directly purify the sewage, and then carry out unified planning and treatment of pollutants, but the domestic sewage contained in urban sewage and Industrial sewage often contains a large amount of waste heat. Although the sewage is purified, most of the current devices used for urban sewage treatment do not have the structure to recycle the waste heat in the sewage, which leads to the direct loss of the waste heat in the sewage. It causes a waste of thermal energy resources, which does not meet the current energy-saving and environmental protection guidelines. In addition, most of the existing urban sewage treatment equipment only has one or one purification process, resulting in an unsatisfactory effect on sewage treatment.
