Circulating sewage treatment device

Abstract

The invention discloses a circulating sewage treatment device. The device structurally comprises a sewage treatment machine, a water inlet pipe, a sedimentation tank, a filter tank, a contact oxidation tank, a disinfection tank, a liquid storage tank, a disinfection mechanism, a water suction pump and a circulating water pump. A water flow drainage mechanism is controlled to release a disinfectantthrough the flow of the sewage, so the disinfectant can be directly and automatically guided in by utilizing a disinfection filter plate, and the disinfectant does not need to be manually released; arotating ring is controlled to drive a folding valve plate to be closed in a liquid injection pipe to control the flow of the disinfectant, so the release amount of the disinfectant can be effectively controlled, and the situation that the purified sewage is not thoroughly disinfected or the disinfectant is residual in the purified sewage due to large waste of the disinfectant is avoided; and thedisinfection filter plate utilizes a waterproof electromagnet to generate an electromagnetic field to attract a magnetic stirring mechanism to rotate, so that the disinfectant is added and blended into the sewage, so the purification of the disinfectant to the sewage is accelerated, the use cost and the energy consumption are reduced, and the concept of energy conservation and environmental protection is met.

Description

technical field [0001] The invention relates to the field of sewage treatment devices, in particular to a circulating sewage treatment device. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for drainage or reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. In the field, more and more people have entered the daily life of ordinary people to use physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve wastewater recycling and reuse, making full use of water resources. [0003] At present, the existing circulating sewage treatment equipment cannot effectively control the release of disinfectant when disinfecting the purified sewage during use, resulting in either insufficient disinfection of the purified sewage or a lar...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing circulating sewage treatment equipment cannot effectively control the release of disinfectant when disinfecting the purified sewage during use, resulting in either insufficient disinfection of the purified sewage or a large waste of disinfectant. As a result, the purified sewage still contains disinfectant. In order to avoid the use of disinfectant, the motor drives the stirring shaft to stir the bottom of the sewage treatment tank, which increases the use cost and energy consumption. It does not conform to the concept of energy saving and environmental protection. There are also deficiencies in the use of boards
