Background

Most tap water in China is mainly used for treating water sources containing pathogenic microorganisms, colloidal substances, suspended matters and the like in the process of applying a water treatment process. Generally, the conventional water purification techniques used in water works employ coagulation, sedimentation, filtration, disinfection, and the like. These processes are widely used in many waterworks in China. The coagulant commonly used in the coagulation process is polyaluminium chloride and the like, and the coagulant aid and the pH adjustment in the coagulation process are rarely used. After decades of development, various treatment structures with different forms and performances suitable for various situations have been developed, such as flocculation facilities of rapid mixing, hydraulic or mechanical stirring, and different structures and types of sedimentation, clarification tanks, filtration facilities with air-water back washing, homogeneous filter materials, multi-layer filter materials, etc., among which the V-shaped filter tank has been widely used. Due to the limitation of technical and economic conditions, in most domestic waterworks, the originally used disinfectant is mainly liquid chlorine, and the rest waterworks can use sodium hypochlorite, chlorine dioxide and the like with higher safety performance. In the aspect of water purification processes of water works in China, the processes are common, and the purpose of the application of the processes is to enable drinking water to meet relevant standard requirements, so that people can safely use the water.

However, the traditional water purification technology has the following problems:

1, the sedimentation and filtration unit occupies large area, has higher construction investment cost and is inconvenient to transport and construct;

2, the traditional water purification technology is difficult to remove soluble pollutants in water by a precipitation and filtration unit, and if raw water is polluted, the treatment effect is not ideal;

3, after the flocculating agent is added, the floc in the water cannot be completely removed, so that aluminum residue is caused, and the health of a human body is threatened;

4, the water quality fluctuation of raw water cannot be coped with, and when the turbidity of the raw water is lower than or exceeds the designed treatment capacity, the treatment effect is not high, so that the water supply quality is influenced;

5, the problem of bacterial residue exists, because the traditional chlorination disinfection mode can cause bacteria to generate antibodies, the disinfection is not thorough, the bacterial residue appears in a water supply pipeline, and the water safety is influenced;

6, the automation degree is low, and a plurality of procedures need to be completed manually, thus wasting time and labor;
