Wastewater treatment device

Abstract

The invention discloses a wastewater treatment device. The wastewater treatment device comprises a water tank of a hollow structure with a trapezoidal bottom, a sludge collecting tank is arranged at the trapezoidal bottom of the water tank, a water inlet is formed in one side of the bottom of the water tank, and a transmission box is arranged in the middle of the side, closely adjacent to the water inlet, of the water tank. Sliding grooves are symmetrically formed in the inner wall of the water tank, and sliders are sleeved with the sliding grooves respectively. First springs are symmetricallyarranged on the two sides of each slider, the two ends of the first springs are fixedly connected with the inner walls of the sliding grooves respectively, and bearings are sleeved with the sliders respectively. A rotary shaft penetrates through the bearings and is symmetrically inserted between the bearings, the rotary shaft is sleeved with a filter cylinder, a brushing plate is clamped to the filter cylinder, and the two ends of the brushing plate extend to the inner wall of the water tank. The wastewater treatment device has the advantages that the overall design is simple and reasonable,due to the design, wastewater is thoroughly purified, the problem that a filtering device is blocked is solved, the wastewater treatment efficiency is improved, the discharge quality of the wastewaterobtained after treatment is ensured, and the wastewater treatment device has a certain practicability.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment device. Background technique [0002] Water resources are the most critical resources for human production and life, but nowadays, the ecological environment has been severely damaged and water bodies are seriously polluted. The protection of water resources and the control of water pollution have become the most concerned issues in modern society. In the case of shortage of water resources and severe water pollution, it is necessary to treat the polluted water so that the polluted water can be reused after treatment. However, the existing sewage treatment process is relatively simple and incomplete, resulting in more suspended or precipitable solid substances remaining in the sewage, which affects the quality of the discharged water after sewage treatment. Moreover, the long-term use of the equipment will cause sediment to adhere to the inner wall of the purif...

Problems solved by technology

However, the existing sewage treatment process is relatively simple and incomplete, resulting in more suspended or sedimentable solids remaining in the sewage, which affects the quality of the discharged water after sewage treatment

Moreover, the long-term use of the equipment will cause sediment to adhere to the inner wall of the purification device, which will easily cause the blockage of the filter screen, which is not conducive to the purification of water quality.

[0003] For the problems in related technologies, no effective solutions have been proposed yet
