Method for purifying ultra-vast water and purifying device

Abstract

The invention relates to a method for purifying a super great amount of water, which comprises the following steps: step I, the target water is selected; step II, the reference water depth(D1) is determined; when the actual depth of the target water is 10-50 meters, the reference water depth is the actual depth; when the target water depth is more than 50 meters, the reference water depth(D1) is 50 meters; step III, a purifying device, an air water-raising tunnel, is arranged in the target waters, and the tunnel body length (L1) of the air water-raising tunnel is 30 percent-50 percent of the reference water depth(D1) of the target water; the submerged depth of the tunnel mouth (D2) of the air water-raising tunnel is 40 percent-60 percent of the tunnel body length (D1); step IV, the air is input into a pressure chamber of the air water-raising tunnel and the air pressure(P1) of an air compressor is 150 percent-200 percent of water pressure in the pressure chamber. The invention can realize convection of an upper water layer and a lower water layer as well as realize the whole circulation, thus effectively facilitating dissolved oxygen quantity in the whole waters, damaging suspension state of algae and inhibiting the growth of the algae so as to purify the water.

Description

technical field [0001] The invention belongs to the technical field of in-situ restoration of water quality. Background technique [0002] There are two types of devices used for in-situ restoration of the water quality of reservoirs and lakes: [0003] One is to arrange perforated air ducts at the bottom of the lake, and use an air compressor to input compressed air into the perforated air ducts at the bottom of the lake to generate a large number of small air bubbles in the water for aeration, thereby mixing the upper and lower water layers and increasing the concentration of dissolved oxygen in the lower water body , Improve water quality. There are many studies on laying perforated air ducts at the bottom of the lake, and the technology is relatively mature, but the efficiency of this equipment is low. [0004] The other type is to arrange air pumping cylinders in the water. The structure of the air pumping cylinders is shown in Figure 1. [0005] Please refer to Figu...

AI Technical Summary

Problems solved by technology

If these small air bubbles are fused into several medium-sized air bubbles, rising sequentially without intermittency, air bombs and plunger suction cannot be formed, and the water lifting effect is very poor.

However, the aeration chamber of the existing water pump is in the shape of a straight cylinder, which is not conducive to the merger of the small bubbles overflowing at the same time. Only by accurately controlling the output air pressure of the air compressor can these small bubbles be fused into a complete air bombs, and there is no data about air compressors recorded in the prior art

[0010] 3. The in-situ restoration of water quality using the air pumping cylinder involves the issue of energy efficiency ratio. Therefore, when using this method for in-situ restoration of water quality, some basic parameters must be determined, such as cylinder radius R1 and cylinder length L1 , the submerged depth D2 of the cylinder mouth, the height L2 of the aeration chamber, the submerged depth of the lower edge of the aeration chamber, and the air pressure output by the air compressor. There is no systematic and complete data in this regard in the prior art
