Water pollution is the current concern of everyone, because with the improvement of people’s living standards, water pollution is becoming more and more serious, to prevent and control is a very important link. This chapter water quality online monitoring instrument manufacturers to understand together with you about the prevention of arsenic pollution in water measures and treatment methods. The steps are as follows:

· Strengthen environmental monitoring, establish a prediction mechanism for arsenic pollution in air, water and other fluids in key areas, and strengthen the monitoring of arsenic in soil, so as to solve the problem of water use for human and livestock and agricultural irrigation in high-arsenic areas;

When it comes to the monitoring of the water environment, it is inseparable from the water quality online monitor, to detect the content of arsenic in water, you can use the T8000-As water arsenic online analyzer produced by Hangzhou Modi. This instrument can monitor the total arsenic content in water by molybdate/ascorbic acid colorimetry in real time.

· Management of highly arsenic-containing minerals and their smelting process, banning local arsenic-smelting factories, arsenic smelting factories and other gold smelting factories must meet the standards before the “three wastes” can be discharged, and take mandatory dearsenification treatment of high-arsenic coal to fundamentally reduce the arsenic content in the air;

· Strengthen the management of arsenic-containing chemical products, such as arsenic-containing pesticides and medicines. Learn relevant knowledge when necessary to reduce the occurrence of artificial poisoning as much as possible.

· Avoid arsenic entering the food to prevent it from entering the human body through drinking water or food.

Faced with the situation of arsenic pollution, it is not easy to reduce the harm of physical poisoning and carry out effective prevention and control. Relevant departments have shown through research that to reduce the harm of arsenic poisoning, improving water quality is also very important! Do not use water with high arsenic contamination for irrigation, and do not allow plants grown on arsenic-contaminated soil to enter the food chain.

If There is Related Pollution, How Should Be Treated?

Arsenic pollution must be treated in time to prevent a larger area of harm. There are three main methods of arsenic pollution control: chemical method, physical method and biological method. The details are as follows:

· Chemical method: It refers to the use of chemical reagents to make arsenic into arsenic compounds that are difficult to be absorbed by the human body, such as adding lime, ferrous sulfate and liquid chlorine (or bleaching powder) in the arsenic containing wastewater, the arsenic precipitation, and then the waste residue treatment, or the arsenic containing wastewater through the iron sulfide filter bed or with iron sulfate, ferric chloride iron hydroxide coagulation precipitation.

· Physical method: It is mainly to let arsenic-containing sewage through a special filter to enrich arsenic and turn waste into treasure. For example, activated carbon filtration method.

· Biological methods: mainly refers to the planting of plants that can absorb arsenic in arsenic polluted soil or water to achieve the purpose of absorbing arsenic, such as American scientists found a fern that can absorb arsenic in polluted soil.
