Water treatment system and water treatment device

Abstract

The invention relates to a water disposal system, comprising a swirl rough filter which is communicated with the feeding water to be disposed, a water disposal device which is connected with the swirl rough filter, and a disposed water collecting box which is used for collecting the disposed water which is disposed by the water disposal device; wherein, the water disposal device comprises a radial swirl filter; the middle part of the shell of the mainbody of the radial swirl filter is communicated with a tangent water outlet, the upper part thereof is provided with a ring-shaped overflow device and a lower part thereof is provided with a conical medium supporting screen and filled by filter medium; the bottom of the overflow device is provided with a supporting frame and vanes which are obliquely arranged on the supporting frame; the supporting frame, the vanes and the radial swirl filter shell form the ring-shaped sleeve; water which is disposed by the radial swirl filter flows into the disposed water collecting box. The water disposal system leas more water to be circulated and reused, has simple structure, few part numbers, low cost, is easy for large-scale production, economical running, installation and operation. The invention also relates to a water disposal device used for the water disposal system.

Description

technical field [0001] The invention relates to a water treatment system for domestic and industrial water, in particular to a water treatment device. Background technique [0002] Currently, there is an increasing demand for water all over the world due to increasing population and demand for Western-style living standards in emerging countries. The consequence of this is that the demand for water is greater than the available water sources. The resulting knock-on effect is that the original water supply infrastructure construction is now unable to meet the additional water demand, and the existing sewage drainage system and sewage treatment plant cannot meet the ever-increasing treatment volume. Therefore, the tertiary treatment of drinking water and the recycling of sewage such as gray water or rainwater are becoming more and more important. "Reclaimed water" refers to the water produced after sanitary water is used for bathing, cleaning, laundry or washing dishes. [...

AI Technical Summary

Problems solved by technology

[0014] 1. If the filter is not replaced regularly, there is a possibility of no-load, that is, more pollutants accumulate on the filter surface;

[0015] 2. Even if the filter is replaced regularly, there may be a high concentration of unwanted substances in the filter medium. Although the amount of such substances is small at first, due to the continuous increase of such substances, the removal of such substances will bring difficulties. trouble
