specific Embodiment approach 1

[0046] Specific implementation mode one: combine figure 1 The antifouling metal membrane module filter based on the microelectric structure of the present invention is described. In this embodiment, the anti-pollution metal membrane module filter based on the microelectric structure is composed of a flocculation adjustment tank 1, a metal membrane separation tank 2 and a backwashing system. Clean water and discharge sludge from the bottom; the backwashing process starts after the filtration process stops, and adopts the operation mode from the back to the front, the backwashing water pump enters water, and the front sludge pump drains water.

specific Embodiment approach 2

[0047] Specific implementation mode two: combination figure 1 To illustrate the flocculation homogeneity method of the present invention, the flocculation regulating tank 1 is located at the front end of the metal membrane separation tank 2 . The flocculation regulating tank 1 includes a sewage inlet pipe 1-1, a stirring paddle 1-2, a sludge discharge pipe 1-3, a sludge pump 1-4 and an overflow hole 1-5, wherein:

[0048] The sewage inlet pipe 1-1 is arranged on the front wall of the flocculation adjustment tank 1;

[0049] The overflow holes 1-5 are arranged on the top of the rear wall of the flocculation adjustment tank 1;

[0050] The stirring paddle 1-2 is arranged inside the flocculation regulating tank 1;

[0051] The mud discharge pipe 1-3 is arranged at the bottom of the flocculation regulating tank 1;

[0052] The sludge pump 1-4 is connected with the sludge discharge pipe 1-3.

Abstract

The invention discloses an anti-fouling metal membrane assembly filter based on a micro-electric structure and a water purifying method thereof. The filter comprises a flocculation regulating tank, ametal membrane separation tank and a backflush system, wherein the fluctuation regulating tank comprises a sewage inlet pipe, a stirring blade, a sludge discharging pipe, a sludge pump and an overflowhole; the metal membrane separation tank comprises a tank body, a chain type sludge scraper, a metal membrane assembly, a water inlet perforated water distribution groove and an external power supply; the backflush system comprises a backflush water pump, a draining valve, clean water collection branch pipes and a clean water collection main pipe. By adopting the anti-fouling metal membrane assembly filter, the metal membrane filtering assembly is adopted to replace filter cloth, and a metal filtering side carries negative charges under the action of an external electric field for inhibitingthe apposition growth of particles carrying negative charges and microorganisms on the surface of a metal filtering membrane, so that the anti-fouling performance is improved, and the service life andbackflush period of the metal filtering membrane are prolonged. The metal membrane assembly is fixed obliquely at an angle of 60 degrees relative to the horizontal plane, and a top perforated water distribution groove is designed, so that the separation performance is enhanced, the tank size is reduced, and the building cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of deep purification and treatment of sewage, and relates to a filter tank based on a microelectric structure anti-fouling metal membrane module and a water purification method thereof. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, the total amount of urban sewage discharge has increased, and environmental pollution has intensified; the water demand for urban production and living has risen sharply, and the shortage of water resources has intensified. This situation is bound to become an obstacle to my country's economic development. Therefore, improving the efficiency of sewage treatment, improving sewage discharge standards, and realizing reclaimed water reuse are necessary ways to protect the ecological environment and sustain economic development. For this reason, the "Water Pollution Action Plan" pointed out that: the sewage discha...
