Embodiment

[0053] Taking the water intake tower of Heihe Reservoir as an example, the water intake tower is an upright box-type water intake tower. The water depth of the reservoir is about 80m. The length and width of the water intake tower are 16m and 8m respectively.

[0054] The microfiltration membrane adopts PVDF membrane. The inner and outer diameters of the hollow fibers are 600um and 1000um respectively, and the membrane pore diameter is 0.2um. The geometric dimensions of a single membrane module 24 are 302mm in diameter and 1405mm in height. 2 , each membrane module small unit is composed of 6 membrane modules connected in parallel, each membrane module large unit is composed of 6 membrane module small units connected in parallel, and the membrane module large unit is set in 4 groups. The membrane module is installed at about 20m underwater (working pressure 0.2MPa). The device is expected to have a processing capacity of 15,000m 3 / d.

Abstract

The invention discloses an integrated coagulate / immersed membrane filter water quality purifying intake tower, comprising an intake tower arranged at one side of an arch dam in a reservoir, wherein a medicament dosing chamber is arranged in the intake tower; an upright membrane component is arranged in the intake tower below the medicament dosing chamber; the distance from the membrane component to the water level of the water tower is 15-25m; a backflush water pipe is connected to the middle part of the upper end face of the membrane component; a water outlet pipe is connected to the lower end face of the membrane component; the connection position of the water outlet pipe and the backflush water pipe are on the same axis; the water outlet pipe is arranged along the lateral wall of the intake tower and is led to a clean water pond; an air pipe is connected to the position which is 1 / 4 of the diameter of the membrane component to the water outlet pipe at the lower end face of the membrane component; an inclined plate is arranged outside the membrane component; and the inclined plate is orderly provided with tower slope covers without bottom surfaces from top to bottom. Raw water of a water source can be effectively purified by the integrated coagulate / immersed membrane filter water quality purifying intake tower. Compared with the existing similar equipment, the integrated coagulate / immersed membrane filter water quality purifying intake tower has the advantages of good water outlet quality, simple structure, low operation cost and the like, and is convenient to dismantle and repair; energy consumption is reduced; and the land is also saved.

Description

technical field [0001] The invention relates to a purification structure in the technical field of water supply, in particular to a coagulation / immersion membrane filtration water quality purification water intake tower integrating water intake, flocculation, sedimentation, membrane filtration and backwashing. technical background [0002] Due to the pollution of the water environment to varying degrees and the continuous improvement of drinking water quality standards, it is difficult to meet the new water quality standards for chlorine disinfection by-products, Giardia and Cryptosporidium in water treated by traditional processes. Therefore, how to improve the quality of water supply It is an important topic in the field of water supply to reduce infrastructure and operating costs as much as possible. [0003] Membrane filtration technology is a newly emerging water treatment technology, which can effectively reduce impurities, bacteria and pathogenic bacteria compared wit...
