Embodiment Construction

[0046] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0047] According to Figure 1 and figure 2 , the present invention includes an industrial tank body, as shown in Figure 1, the first partition A and the second partition B are arranged in the industrial tank body, and the first partition A and the second partition B divide the inside of the industrial tank body into successively Biochemical Zone 1, Membrane Zone 2 and Water Zone 3.

[0048] As shown in Figure 1, the first lift pump 4 that is arranged in the lake connects pipeline 41, is communicated to biochemical area 1, as Figure 1 and figure 2 As shown, an aeration pan 11 is set in the biochemical area 1, and the aeration pan 11 is installed in the lower part of the biochemical area 1, and the biochemical area 1 has activated sludge for microbial degradation. In the present invention, the biochemical zone 1 is a facultative oxygen zone, which is only u...

Abstract

The invention relates to a method and device for improving lake water and relates to water treatment. The device comprises an industrial tank body which is provided with a first partition board and a second partition board which divide the industrial tank into a biochemical region, a filter membrane region and a clear water region, wherein a first lift pump is communicated to the biochemical region, the filter membrane region is provided with a membrane component which is connected with a second lift pump and is communicated to the clear water region, a perforated aerator pipe is arranged under the membrane component, a lower part of the clear water region is provided with a recoil pump, and an upper part of the clear water region is provided with an UV light disinfection device. The method comprises the following steps: 1) the biochemical region pumps lake water from a lake, and microorganisms in activated sludge degrades contaminants, 2) lake water overflows from the biochemical region flows to the filter membrane region, 3) the contaminants are further degraded and filtered and separated by a micro filter membrane, and an effluent enters a clear water pond, 4) lake water in the clear water region is treated by the UV light disinfection for UV light disinfection, and 5) the recoil pump operates to return the lake water in the clear water region to the lake through an output pipe. The method and device have advantages of no influence on landscapes, low cost and quick results.

Description

technical field [0001] The invention relates to a treatment method for a lake water body, in particular to a lake water restoration method and device. Background technique [0002] The urban lake ecosystem has service functions such as regulating ecology, culture and entertainment. With the acceleration of urbanization in our country, many cities have not effectively protected the inner lakes of the city while developing at a high speed. Many lakes show different degrees of eutrophication. The ecological landscape function of urban lakes has been severely damaged, so urban lake governance is an urgent problem to be solved in many cities to improve the ecological environment. [0003] Compared with general domestic sewage and water pollution, lake water mainly has the following characteristics: [0004] (1) The selected target water area is small [0005] Most of these lakes have relatively closed water areas, poor ability to digest and degrade pollutants themselves, and ha...
