In fact, when it comes to pesticides, they are chemical agents whose functions are to prevent and control pests and diseases as well as regulate the growth of plants. It is widely applied in agricultural, forestry, animal husbandry production, environmental and household hygiene pest control and epidemic prevention, etc. However, it is a toxic substance. Once ingested into the human body, the consequences are unimaginable! This requires appropriate treatment of pesticide wastewater. In this chapter, the editor will learn about the methods of treating pesticide wastewater together with everyone!
There are many types of pesticides, and the water quality of their wastewater is very complex. The main characteristics are manifested in the following aspects:
1.The concentration of pollutants is high, and the chemical oxygen demand can reach tens of thousands of milligrams per liter.
2.It is highly toxic. Besides pesticides and intermediates in the wastewater, it also contains toxic substances such as phenol, arsenic and mercury, as well as some hard-to-degrade organisms.
3.It can smell a foul odor, which has an irritating effect on the respiratory tract and mucous membranes of the human body.
The water quality and quantity are not very stable.
In this way, the environmental pollution caused by pesticide wastewater can be imagined. Treating it means reducing the concentration of pollutants in the wastewater from pesticide production, enhancing the recycling rate, and ensuring it poses no harm.
So, what are the methods for treating pesticide wastewater? In fact, there are many methods. It depends on which one you need to use! The specific methods include activated carbon adsorption, solvent extraction, wet oxidation, activated sludge process, etc. Of course, developing new pesticides that are highly efficient and low-toxic is the discovery of the development of this industry!
In addition, to monitor various indicators in pesticide wastewater, a water quality analyzer is needed. Different parameters correspond to different water quality testing devices. Among them, the content detection of organophosphorus pesticides can be monitored in real time by the OP-8000 total phosphorus online analyzer to determine its content in water.
