Li De rural drinking water treatment plan

Time: 2019-10-29
The safety of drinking water is closely related to the lives of millions of households. The rural drinking water safety project is not only an important measure to improve the quality of drinking water and the quality of life of farmers, but also a public welfare undertaking. To solve the problem of poor quality of drinking water in rural areas, we need to make a concrete analysis of the water quality of rural drinking water, and formulate a scientific and rational scheme for the purification of rural drinking water.
To solve the problem of poor quality of drinking water in rural areas, corresponding water treatment measures should be taken for different water quality problems. Before the implementation of the rural drinking water project, in view of the characteristics of water resources in the mountainous area, the geographical conditions of water supply, the water consumption status and the location of the water source, a reasonable water treatment process is designed, with strong processing capacity (water quality up to standard), convenient transportation and installation (small footprint, light weight, small structure), durability (moisture resistance, corrosion resistance, long service life), and safety (no pollution, no rust water). Water treatment equipment. Next is Rural drinking water treatment scheme To illustrate:
First, Equipment features:
One The traditional coagulation, sedimentation, filtration and other water purification processes are combined in one equipment, with less land occupation and convenient installation. Chinese style
Two It is automatic and intelligent. According to the needs of users, the whole process of computer control can fully realize man-machine conversation. In addition to the management of water pumps and dosing systems, equipment is automatically operated from influent, coagulation, sedimentation, filtration, effluent, backflushing, sewage disposal and so on, without manual operation. A kind of
Three The water quality is stable, reliable and water is sufficient. When the turbidity of the source water reaches 3000 mg / L, the turbidity of the effluent can be stabilized below 3 mg / liter, reaching the turbidity standard of running water.

Two. Process flow:
The water source, the pump, the sand filter, the carbon filter, the precision filter, the slow release sterilizer, the water tank.
Three. Technical specifications
It includes raw water pump, quartz sand filter, activated carbon filter and precision filter. Its main function is to remove particles, colloids, organic compounds, chromaticity, residual chlorine and bacteria in raw water. A kind of
1) The working principle of mechanical filter is: mechanical filter is a pressure type filter, which uses the refined quartz sand filter material filled in the filter. When the water flows through the filter layer from top to bottom, the suspended solids and viscose paper particles in the water are removed, thus reducing the turbidity of the water.
When the equipment runs to a certain time, it will stop operation and backwash. The backwashing time is 15 ~ 20min. Regular manual control.
The turbidity of the mechanical filter is generally less than 2 degrees, and the SDI (pollution index) can generally be below 4 degrees.
2) Activated carbon filter activated carbon is the main adsorbent widely used in water treatment. During the activation process, all the shapes and sizes of the gap between the MICROTEK lattices form a huge surface area. Therefore, the carbon water contact surface is very large and the adsorption capacity is very strong. It can effectively ensure the service life of the follow-up equipment and improve the water quality of the effluent. In the pure water manufacturing process, the role of activated carbon is mainly manifested in four aspects: reducing the oxidation degree of water; removing residual chlorine in water; removing three halide (THM) in water.
3) The precision filter precision filter is equipped with a plurality of polypropylene melt blown filter cores, which are replaced when the 1kg/cm2 pressure difference is reached.

4) The slow release sterilizer of slow release sterilizer adopts chemical reaction, automatic slow release, delayed pressure and chlorination process. With the strong chlorine solid content of more than 90% as the main raw material, the disinfectant produced by the reasonable mixing of water and medicament is added to the pool, water well, pipeline and sewage pool to reach the sterilization effect.
