Integrated slow sand filtration water supply device

Abstract

The invention discloses an integrated slow sand filtration water supply device, which belongs to water supply equipment and mainly solves the problem that the traditional slow sand filtration water supply device has a single structure and a single function. The integrated slow sand filtration water supply device comprises a water purification device, wherein the top part of one side of the water purification device is provided with a water distribution channel which is communicated with the top part of a filtration layer; the bottom part of the filtration layer is connected with a water collection channel which is communicated with a contact reaction area; the contact reaction area is communicated with a water storage area through an overflow weir; a lifting pump is arranged in the water storage area; the bottom part of the overflow weir is provided with a communication valve; a headstock gear controlling the communication valve is arranged outside the overflow weir; and a guide wall is arranged in the water storage area. The integrated slow sand filtration water supply device integrates water purification, sterilization, storage and lifting and has better purification effect, high water volume regulation capacity, small floor area, convenient management and no back flush. The device is particularly suitable for small-scale water purification and supply in villages, towns, military subcamps and the like.

Description

technical field [0001] The invention relates to a water supply equipment, in particular to a water supply device related to the purification, disinfection, storage and lifting of water in reservoirs and lakes. Background technique [0002] The shortage of water resources is one of the most serious resource problems faced by mankind in the 21st century. Only 1 / 4 of the world's population can drink clean water that meets the standards, and 1 / 3 of the population cannot get safe water. The situation of water shortage is becoming more and more serious. my country is one of the 13 countries with the poorest water resources in the world. Due to the excessive use of groundwater resources for a long time, it has become increasingly scarce, and people have to use more and more surface water. At present, due to the increasingly serious water pollution, conventional water treatment coagulation, sedimentation, filtration and disinfection processes have limited removal of pollutants, esp...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problem of single structure and function of the existing slow filter water supply device, the present invention provides a new type of integrated slow filter water supply device, which realizes water purification, contact reaction and Integrated with storage, it not only saves costs, but also ensures that the water quality after purification will not be affected by other process equipment. It is very suitable for small-scale water purification and supply in towns and army camps.
