Purification barrier for river regulation

Abstract

The invention discloses a purification barrier for river regulation. The purification barrier comprises a tank, PP cotton, front activated carbon, precision activated carbon, a hollow fiber ultrafiltration membrane and rear activated carbon. The rear portion of the tank is provided with three fixing cones, one side panel of the tank is provided with holes, and a cover is arranged above the tank. By substitution of original filter materials such as cobblestone, soybeans and fine sand with PP cotton, activated carbon and the ultrafiltration membrane, metal ions, toxic bacteria and odor in watercan be eliminated on the basis of rough filtration of particles in river water, and accordingly water purification can be realized. By placement of filter elements in the transparent plastic tank andindependent arrangement of each filter element in a single groove, filter element utilization conditions can be observed clearly; by observation of the filter element utilization conditions, the filter elements can be taken out and replaced after the tank is uncovered, replacement of the tank is avoided, and resource saving is realized.

Description

technical field [0001] The invention belongs to the technical field of purification, and in particular relates to a purification barrier for river treatment. Background technique [0002] With the rapid development of industry and agriculture in my country and the improvement of people's living standards, the requirements for water quality are getting higher and higher. However, due to the influence of soil erosion, water source pollution and other factors, the composition of surface water has gradually become more complex, the organic composition has increased, and the difficulty of drinking water treatment has increased. Conventional drinking water treatment process with coagulation, sedimentation, filtration, disinfection as the main steps, with removal of turbidity and bacteria as the main purpose, has gradually increased in the water body in recent years some trace organic pollutants, such as herbicides, insecticides The removal effect is extremely limited. In additio...

AI Technical Summary

Problems solved by technology

[0004] The purification barriers of the prior art have the following problems: 1. Most of the current purification equipment uses pebbles, fine sand, etc. as filter materials, so that the river water can only be roughly filtered, and only impurities in the water, toxic substances in the water and Bacteria still exist in the water, so the water treatment is unreasonable, and the water cannot be completely purified; 2. The existing purification barriers are all integrated inside. After a long time of use, the internal filters need to be replaced. The shell is also replaced, and the interior cannot be replaced separately, resulting in a waste of resources and not environmentally friendly.
