Efficient sewage treatment system and efficient treatment method thereof

Abstract

The invention provides an efficient sewage treatment system and an efficient treatment method thereof. The efficient sewage treatment system comprises a large-particle filter tank, a membrane filamentfilter tank, a sludge treatment tank, a sludge dewatering tank, a sludge conveying device, a hydrolysis tank, a PH value regulating tank, a biological filter tank and a disinfection tank. The treatment method comprises the following steps of: firstly, primarily filtering sewage through the large-particle filter tank; feeding the sewage into the membrane filament filter tank, filtering the sewageand the sludge by the membrane filament filter tank and then respectively feeding the sewage and the sludge into the sludge treatment tank and the hydrolysis tank; conveying the sludge in the sewage treatment tank into the sludge dewatering tank for dewatering and then conveying the dewatered sludge out through the sludge conveying device; and hydrolyzing the sewage in the hydrolysis tank, feedingthe hydrolyzed sewage into the PH value regulating tank, filtering the regulated sewage through the biological filter tank, feeding the filtered sewage into the disinfection tank for disinfection, and finally discharging the treated sewage. According to the invention, large-particle substances are filtered, and the membrane filament filter tank is additionally arranged on the basis of the hydrolysis filter tank and the biological filter tank, so that the filtering efficiency is improved while the filtering effect is improved.

Description

technical field [0001] The invention belongs to the field of high-efficiency sewage treatment system and its high-efficiency treatment method, and in particular relates to a high-efficiency sewage treatment system and its high-efficiency treatment method. Background technique [0002] With the rapid development of urbanization and industrialization, my country's water environment has been severely damaged and has a tendency to continue to deteriorate. Sewage discharge not only seriously affects the daily life of residents, but also destroys the ecological balance of nature. In order to reduce the discharge of sewage, sewage treatment plants have been established all over the country. However, there are still long-term problems in the sewage treatment process, such as excessive power consumption, high operating costs, secondary pollution caused by by-products, and excessive water output due to improper operation control. Therefore, it is of great significance to study the op...

Sewage discharge not only seriously affects the daily life of residents, but also destroys the ecological balance of nature

In order to reduce the discharge of sewage, sewage treatment plants have been established all over the country. However, there are still long-term problems in the sewage treatment process, such as excessive power consumption, high operating costs, secondary pollution caused by by-products, and excessive water output due to improper operation control. Therefore, it is of great significance to study the optimization control of the new sewage treatment process to achieve energy saving and consumption reduction, which is an inevitable development trend of the sewage treatment industry in the future

[0003] In response to the requirements of national sustainable development and the improvement of people's awareness of environmental protection, both domestic sewage and industrial sewage must be filtered before they can be discharged. Nowadays, some relatively large sewage treatment devices can achieve clean water to a certain extent. effect, and protect the ecological environment to a certain extent, but because the current sewage treatment equipment has not formed a system, after a period of use, various problems appear, such as the high failure rate of the pretreatment section equipment , the interception effect is poor, causing the reaction tank to carry large solid suspended matter, affecting biochemical reactions and effluent water quality

And due to the limitations of the traditional sequencing batch reaction tank process, there is only an aerobic environment in the process, and it is difficult to form an anaerobic and anoxic environment, and the reaction time is short

The aerators in the reaction tank operate alternately, and the aerators cannot work stably for a long time, resulting in a high failure rate during operation
