Abstract

The invention discloses a self-cleaning filtering system for water purification treatment, and a filtering treatment method of the self-cleaning filtering system. The self-cleaning filtering system comprises a front filtering structure and a rear treatment structure, wherein water flow sequentially passes through the front filtering structure and the rear treatment structure, the water outlet endof the rear treatment structure is communicated with a back washing device, and the front filtering structure and the rear treatment structure respectively cut off water flow self-cleaning washing. According to the invention, the self-cleaning filtering system for water purification treatment and the filtering treatment method of the self-cleaning filtering system have the effect of effectively filtering out particle impurities in water.

Description

technical field

[0001] The invention relates to the field of water purification treatment, in particular to the field of water purification filtration treatment. Background technique

[0002] The water resources on the earth are limited, and the water sources that can satisfy human consumption are very scarce. Therefore, attention should be paid to the protection of water sources; ordinary tap water often needs to be filtered and disinfected before being used directly. It is directly quoted by humans; while the automatic cleaning function of general filter equipment is relatively poor, so the filter equipment needs to be replaced after a period of use, which also brings extra costs to the maintenance of filter equipment; and most filter equipment cleaning When the sewage flows out through the waterway, it will also cause damage to the waterway pipeline, resulting in some impurities still remaining in the waterway pipeline.

Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings.

[0041] as attached Figure 1-12 : A self-cleaning filter system for water treatment, comprising a pre-filter structure 1 and a post-treatment structure 2; water flows through the pre-filter structure 1 and the post-treatment structure 2 in sequence; the post-treatment structure 2 A backwashing device 3 is connected to the water outlet, and the pre-filtering structure 1 and the post-processing structure 2 respectively cut off the water flow for self-cleaning and flushing. In this way, the water flows through the pre-filter structure 1 to filter out the particulate impurities in the water, and then through the post-treatment structure 2 to filter out the tiny impurities in the water, which can effectively filter out the impurities in the water and prevent these harmful impurities from affecting human health.

[0042] It also includes a water pipe 4; the two ends of the ...
