Embodiment 1

[0035] A continuous microfiltration filter, consisting of microfiltration membrane filter material (single plug-in membrane module or Y-shaped combined plug-in membrane module), reinforced concrete filter tank (or metal filter tank), water collection filter plate, air-water reverse It is composed of flushing system, pickling system, alkali cleaning system and pre-chlorination system. The microfiltration membrane (MF) is an oxidation-resistant PVDF external pressure hollow fiber membrane with a cut-off pore size of 0.2 μm; a gravity-type microfiltration filter with a domestic membrane flux of 30-35L / m 2 ·h; the filtration capacity per unit effective area of ​​the filter is 16-20m 3 / m 2 h. Imported membrane membrane flux 50L / m 2 h, the filtration capacity per unit effective area of ​​the filter can reach 30m 3 / m 2 h. Pressure microfiltration filter, domestic membrane membrane flux 40L / m 2 ·h; the filtration capacity per unit effective area of ​​the filter is 22~27m 3 / ...

Embodiment 2

[0037] A continuous microfiltration filter, the microfiltration membrane filter material (single plug-in membrane module or Y-shaped combined plug-in membrane module) is filled in the reinforced concrete filter tank, and the filter plate supports the membrane module. The size of the filter plate is 1000×1000 (mm), and the gap between the filter plates is sealed with a sealant. The filter plate is supported by the filter wall, the two ends of the filter wall are connected with the filter pool wall, and the root of the filter wall is connected with the pool bottom. There are several air cushion balance pipes with d=25mm on the top of each filter wall, and 2 to 3 hydraulic balance holes of 700×700(mm) at the bottom. The upper part of the filter is provided with a backwash drain pipe and a chemical cleaning water inlet pipe; the lower part of the filter is provided with a water inlet pipe, an outlet pipe, and a backwash water inlet pipe. A pre-filter chlorine addition pipe is pro...

Embodiment 3

[0039] A continuous microfiltration filter, the MF microfiltration membrane has a cut-off pore size of 0.2 μm, 100% of the particles larger than 0.2 μm in the influent are removed, and the diameter of bacteria is greater than 0.2 μm, so the continuous microfiltration filter has excellent sterilization effect.

Abstract

The present invention relates to an urban sewage regeneration utilization water treatment process and a water treatment process for running water. Said invention is characterized by that it is a continuous microfiltration filter tank water treatment process, said process can utilize MF membrane technique, and makes said MF membrane technique be combined with a fast filter tank. Said invention can raise water quality, and can reduce treatment cost.

Description

technical field [0001] The invention relates to a water treatment process for urban sewage regeneration and utilization and a tap water treatment process. Background technique [0002] The existing urban sewage recycling water treatment process generally uses the effluent from the secondary sedimentation tank of the sewage treatment plant as the water source, and uses the traditional tap water treatment process, namely flocculation, sedimentation, filtration (quartz sand filtration), and disinfection processes for treatment. The most advanced urban sewage recycling water treatment process is membrane technology, which uses the effluent of the secondary sedimentation tank of the sewage treatment plant as the water source, and uses a microfiltration membrane CMF device with a pore size of ≤0.2m for filtration treatment. The total number of bacteria in the effluent of the secondary sedimentation tank of the sewage treatment plant is 10 4 ~10 6 Individuals / mL, the coliform gro...
