Embodiment Construction

[0012] The present invention provides a high-precision filtration and purification water treatment process. First, the water body is passed through the filter element, so that the water body is subjected to the following operations in the filter element:

[0013] 1) Gravity filtration treatment: most of the impurities in the water are collected by gravity when passing through the filter element; preferably, it filters suspended particles with a diameter of 20-50 μm, and the water flow rate is controlled at 10cm / s.

[0014] 2) Inertial collision filtration treatment: Make the impurities in the water inertially hit the fiber layer of the filter element when passing through the filter element; it is preferred to filter suspended particles with a diameter greater than 1 μm, because it has a large impulse , so it will inertially hit the fiber layer, and the greater the air velocity, the greater the collision rate. The preferred water velocity is controlled at 20cm / s.

[0015] 3) D...

Abstract

The invention provides a high-precision water filtration purification treatment process. The process is characterized by adopting 1) filtration treatment through gravity action, 2) filtration treatment through inertial impaction, 3) filtration treatment through direct interception and 4) filtration treatment through permeation step by step when a water body passes through a filter element. The process has the characteristics of high efficiency and high purifying rate and is simultaneously suitable for large-area use for various industrial water sources.

Description

technical field [0001] The invention relates to a water quality filtration and purification process, in particular to a process capable of achieving high-precision filtration. Background technique [0002] my country is a country seriously short of water, where the per capita fresh water is less than a quarter of the world average. And due to factors such as natural geography and climate, the distribution between the north and the south is uneven, and the ratio between the east and the west is uneven. At present, my country's urban water shortage is serious, and the urban water shortage problem has caused serious economic losses and social environmental problems. Water-deficient cities will gradually spread to all regions of the country from the currently concentrated eastern coastal cities in the northeast, north, and northwest regions. [0003] Traditional water treatment methods have become increasingly incapable of dealing with complex sewage sources. For example, due ...
