Device for efficiently purifying eutrophic water

Abstract

The invention discloses a device for efficiently purifying eutrophic water. The device comprises a suspension frame, a suspension barrel, a dialysis space ring, an inner barrel, a water pump, a water draining pipe, a filler and an aerating device, wherein the suspension frame which is coincided with the axis of the suspension barrel is arranged on the upper part of the suspension barrel; the dialysis space ring is coaxially arranged in the suspension barrel so as to divide the suspension barrel into a purifying filtering barrel and an inner barrel, wherein a water feeding hole is formed in the suspension barrel wall of the purifying filtering barrel; the purifying filtering barrel is filled with the filler; the water pump is arranged in the inner barrel, and is connected with the outside through the water draining pipe; the aerating device is arranged at the top of the suspension frame and is connected with the purifying filtering barrel through an air pipe. According to the device, the filler adsorbing culturing microorganism is arranged in the purifying filtering barrel and the microorganism is utilized to degrade and purify the pollutants in water, so that the purposes of gradually purifying water and recovering excellent aquatic ecological environment of water are achieved, the anti-pollution impact capacity of water is enhanced, the water eutrophication is effectively controlled and the original ecological recovering and self-cleaning of water are realized.

Description

technical field [0001] The invention relates to a device for purifying water, in particular to a device for purifying eutrophic water quality with simple structure and good purification effect, and belongs to the technical field of water body purification equipment. Background technique [0002] Generally speaking, water is the source of life. Water resources play a very important role in human survival, life and production. Water resources are irreplaceable important resources and key factors supporting natural ecosystems and social and economic systems. All countries in the world are starting from Various measures have been taken in various aspects to protect the country's water resources. At present, my country's water environment is facing various pressures such as water pollution and water shortage. Lakes and rivers across the country are generally polluted to varying degrees. The problem of eutrophication in water bodies is very serious. Algae and other plankton multip...

Problems solved by technology

At present, my country's water environment is facing various pressures such as water pollution and water shortage. Lakes and rivers across the country are generally polluted to varying degrees. The problem of eutrophication in water bodies is very serious. Algae and other plankton multiply rapidly. Decline, leading to deterioration of water quality, affecting the lake's water supply, aquaculture and recreational functions, if not treated early, it will eventually lead to the degradation and disappearance of the lake

[0003] At present, the main methods of lake governance include physical methods, chemical methods and microbial restoration methods. However, the physical restoration technology mostly adopts water diversion dilution and sediment dredging, which has disadvantages such as temporary, unstable, and temporary but not root cause; Due to the use of chemical agents, the remediation technology has the disadvantages of high cost and easy to cause secondary pollution; the microbial remediation method is limited by equipment and can only be placed on land, and cannot be installed in large-scale water bodies. Therefore, it is mostly used for the purification of industrial sewage. Less used for water purification treatment of natural water bodies
