1 Optimization of conventional processing procedures

Based on new materials and new theories, through optimization and innovation of conventional treatment processes, a new water supply treatment technology is formed, which is embodied in the improvement of coagulation links and disinfection technology
.

Using the new polymeric coagulant ferric sulfate to enhance coagulation in water treatment, and further enhance the use of biological flocculant flocculation rate, which greatly improves the efficiency of coagulation

2 New Water Treatment Technology

(1) Improvement of flocculation technology.
The application of polyferric sulfate coagulant has improved the problems of long cycle, high cost, slow reaction and poisonous catalysts of conventional water purification methods
.

Polyferric sulfate flocculant has a very fast speed in the process of precipitation and can well improve the water purification effect.

(2) Improvement of disinfection technology.
Ozone disinfection technology has the characteristics of fast action and low dosage, and can control the taste, color and smell of iron, manganese and water at the same time, and it will not produce too many pollutants during disinfection, which is better This guarantees the effect of modern water supply treatment
.

However, in application, care should be taken to control the amount of ozone, because the residual ozone will corrode water supply equipment and water treatment systems, and also endanger people's health

(3) Reclaimed water recycling technology Reclaimed water recycling technology includes three methods: physical and chemical treatment, biological treatment and membrane treatment
.

① Physical and chemical treatment method
.

This method is a good combination of activated carbon adsorption technology and coagulation precipitation technology.

② Biological treatment method
.

The biological treatment method is to remove all the degradable organic matter in the sewage through the oxidation and adsorption of aerobic microorganisms, and the biological treatment method includes three treatment methods: anaerobic microorganisms, aerobic microorganisms and facultative microorganisms

③ Membrane treatment method
.

This method is to use membrane technology to treat water, so as to ensure that the water quality meets the corresponding regulatory requirements

Reclaimed water reuse technology is widely used in residential communities where residents live, and it is still very difficult to apply reclaimed water reuse technology within the entire city, but it is a development direction for water supply treatment in the future
