Integrated sewage treatment system and method thereof

Abstract

The invention primarily discloses an integrated sewage treatment system. The technical scheme of the system is as follows: the integrated sewage treatment system comprises a filtering region, a settling region and a disinfecting region. A squeeze filtration device and a vibrating filtering device are arranged in the filtering region; the vibrating filtering device is located below the squeeze filtration device; the settling region is connected to the filtering region through a first flow guide tube; a feeding device, a stirring device and a rotary filtering device are arranged in the settling region; the feeding device is connected to the stirring device; the rotary filtering device comprises a filtering barrel, a reaction barrel and a rotating motor; the reaction barrel is connected into the filtering barrel through an air cylinder; the rotary shaft of the rotating motor is connected to the bottom of the filtering barrel; the disinfecting region is connected to the settling region through a second flow guide tube; a water spray nozzle is formed in the top of the second flow guide tube; and a baffle plate and an ultraviolet lamp are also arranged in the disinfecting region. The system disclosed by the invention purifies sewage by way of squeeze filtration, vibrating filtration, flocculent precipitation and disinfection, so that purposes of simplifying the process, reducing the investment, enhancing the treatment efficiency, lowering the treatment cost and reducing the occupied area are achieved.

Description

technical field [0001] The invention relates to an integrated sewage treatment system and a method thereof. Background technique [0002] Water is a non-renewable resource and an important resource that is indispensable for the sustainable development of society. Urban domestic sewage and industrial sewage are the main causes of water pollution. Domestic sewage and industrial sewage contain a large number of toxic and harmful microorganisms and chemicals. More than 80% of the world's waste water is directly discharged without effective treatment, which greatly pollutes water areas and the ecological environment, causing serious damage to human water safety and water ecological environment, and threatening people's health and normal life. Therefore, how to Removing harmful substances in wastewater and turning waste into benefits by means of sewage treatment is a common issue that the current society faces urgently to be solved. However, the existing domestic sewage treatment...

[0002] Water is a non-renewable resource and an important resource that is indispensable for the sustainable development of society. Urban domestic sewage and industrial sewage are the main causes of water pollution. Domestic sewage and industrial sewage contain a large number of toxic and harmful microorganisms and chemicals. More than 80% of the world's waste water is directly discharged without effective treatment, which greatly pollutes water areas and the ecological environment, causing serious damage to human water safety and water ecological environment, and threatening people's health and normal life. Therefore, how to Removing harmful substances in wastewater by means of sewage treatment and turning waste into benefits is a common issue facing the current society that needs to be solved urgently

However, the existing domestic sewage treatment devices have large overall structure, large investment in facilities, high operating costs, large floor area, complex operation management, high cost, and poor sewage treatment effect. With the development of economy and urbanization With the advancement of the process, the discharge of industrial sewage has increased significantly, and the urban population has increased sharply, resulting in great changes in the amount and quality of sewage entering urban sewage treatment plants, mainly manifested in a substantial increase in sewage volume and pollution of sewage inflow In the existing technology, if the water treatment system is overloaded for a long time, the water quality is difficult to guarantee and cannot meet the sewage discharge standard.
