Water purification system for karst region

Abstract

The invention provides a water purification system for a karst region. A purification layer at the bottom of a water purification pond sequentially consists of an upper purification layer, a middle purification layer and a lower purification layer from top to bottom, wherein the upper purification layer is formed by fillingcoarse sandwith grain size being 0.5m-5mm, the middle purification layer is formed by mixing and fillingmedium sandwith grain size being0.25mm-2mm and coarse sand,and the lower purification layer is formed by mixingfine sand with grain size being0.05mm-0.5mm and medium sand. A water outlet pipe is guided out from the bottom of the lower purification layer, the water outlet pipe which is guided out is divided into a first water pipe and a second water pipe, the first and second water pipes are respectively provided with stop valves, and the first water pipe extends into a water inlet of a slow sand filter. The system is used for solving the problem that water resources in stony desertification regions such as karst region are relatively deficient, the water quality of multipleplaces is relatively poor and huge healthy hidden trouble exists after the water is drunk for a long time, and existing conventional water purification method is not suitable for karst region. The system provided by the invention belongs to the field of water purification of the karst region.

Description

Technical field [0001] The invention relates to a water quality purification system and belongs to the field of water quality purification in karst areas. Background technique [0002] In karst areas with a wide distribution, water is a relatively scarce resource, and in many karst areas, the water quality of water sources is not up to standard. Long-term drinking will cause greater health threats to the human body, and there are great health risks. In this type of area, due to the complex terrain and scattered residential areas, conventional water purification methods are not applicable in karst mountainous areas. Therefore, more local water resources should be used, and corresponding water purification systems should be designed according to the situation. It is very important for residents. Summary of the invention [0003] The purpose of the present invention is to provide a water purification system in karst areas to solve the shortage of water resources in karst and other r...
