Pseudo-membrane water filtering unit assembly and filtering method

Abstract

The invention provides a pseudo-membrane water filtering unit assembly and a filtering method. The pseudo-membrane water filtering unit assembly comprises a cylinder body, wherein a mandrel assembly is arranged in the cylinder body; a superimposed-layer-shaped filtering layer winds the mandrel component, and comprises a screen, filtering cloth and a guide net which are tightly fit together from outside to inside; the filtering method comprises the following steps: firstly, organic matters in sewage is adsorbed by the screen, and the screen can be also used for separating suspended matters in sewage, wherein the water flow amount of each unit assembly is 0.5-10 m<3> / h; then, through screening of the filtering cloth, suspended matter colloids are removed, wherein the water flow amount of each unit assembly is 0.5-10 m<3> / h; finally, the water flows into a center channel inside the mandrel assembly after passing the guide net, and flows out from a water outlet of the mandrel assembly. The pseudo-membrane water filtering unit assembly and the filtering method have the benefits that the filtering precision is high, cleaning is easy, the possibility of blocking through foul is low, the degree of standardization is high, the service life is long, miniaturization is realized as each pipe is 30 kg or below in weight, automatic cleaning is realized, and the water-saving and energy-saving effect is obvious.

Description

technical field [0001] The invention relates to a pseudo-membrane water filtration unit component and a filtration method. Background technique [0002] With the continuous revolution of industry and the continuous improvement of living standards and the implementation of the sustainable development strategy, the requirements for the humanistic and ecological environment are getting higher and higher. Therefore, saving water resources, sanitation water, and reducing water pollution are the primary strategic issues in the contemporary era. my country is the most populous country in the world. There are currently 4,500 cities above the county level, among which large cities with more than 10 million people are developing rapidly, and accelerating urbanization has become a national strategy. Development is the last word, but it cannot be at the expense of the living environment. How to solve the problem of water crisis and severe atmospheric situation has risen to the level o...

Problems solved by technology

[0004] Sand tank technology is the filtration technology of quartz sand in tanks, which is very backward, large and heavy (by tons), consumes a lot of water and electricity, and is prone to odor

The advantages of RO membrane technology are controlled by foreign countries. Only the centrally controlled ultra-micro membrane of "Motian Membrane" has certain advantages among domestic membrane manufacturers. It is mainly used in the filtration of direct drinking water and industrial product extracts, sewage treatment biofilms, and in swimming pools. It cannot be applied, and the cost of replacing sand filter is too high to be applicable, so the application field of membrane technology is limited
