Energy-saving and environment-friendly sewage purification device

Abstract

The invention belongs to the technical field of sewage purification, and particularly relates to an energy-saving and environment-friendly sewage purification device which is characterized in that the energy-saving and environment-friendly sewage purification device comprises a sedimentation tank arranged on the ground, a water inlet tank is arranged above one side of the sedimentation tank, a water inlet condensation and filtration assembly is arranged in the water inlet tank, and a rotating mechanism is arranged in the middle of the sedimentation tank; the top of the rotating mechanism is movably sleeved with a cross beam fixedly connected with the top of the sedimentation tank, the bottom of the rotating mechanism is connected with a sludge removal assembly, one side of the sedimentation tank is fixedly connected with a drainage mechanism, and the top of the sedimentation tank is provided with an isolation shed; a buffer mechanism connected with the inner side wall of the sedimentation tank is mounted below one side, close to the sedimentation tank, of the water inlet tank. The water content of sludge can be reduced, continuous sedimentation, filtration, sludge discharge and drainage of the sedimentation tank are achieved, the utilization efficiency of the sedimentation tank is improved, the sewage purification efficiency is improved, energy conservation and environmental protection are achieved, and peculiar smell gas is prevented from polluting air.

Description

technical field [0001] The invention relates to the technical field of sewage purification, in particular to an energy-saving and environment-friendly sewage purification device. Background technique [0002] Urban sewage treatment refers to the measures taken to change the nature of sewage so that it does not harm the environmental waters. Urban sewage treatment is generally divided into three levels: primary treatment, which uses physical treatment to remove insoluble pollutants and parasite eggs; secondary treatment, which uses biological treatment to oxidatively degrade various complex organic substances in sewage It is a simple substance; the tertiary treatment is the application of chemical precipitation, biochemical, physical and chemical methods, etc., to remove phosphorus, nitrogen, refractory organic matter, inorganic salts, etc. in sewage. As for which level of treatment is more reasonable, it should be determined according to the treatment requirements for the f...

AI Technical Summary

Problems solved by technology

As for which level of treatment is more reasonable, it should depend on the treatment requirements for the final effluent. In the process of sewage treatment, the treated sewage needs to be sedimented, and the sludge and supernatant in the sewage should be separated. The existing The sedimentation efficiency of the sedimentation tank is poor, and the waiting time is long, especially the continuous sedimentation and separation operation cannot be realized, which seriously affects the efficiency of sewage treatment. Therefore, an energy-saving and environment-friendly sewage purification device is needed
