Embodiment 1
[0021] Example 1: "Water quality improvement type": Taking powdered activated carbon as an example, the online deployment and dosing method is applied to drinking water plants to strengthen organic matter treatment.
[0022] Basic situation of a water supply plant in a city: the daily water supply of the plant is 15×10 4 m 3 / d, under normal circumstances, the effluent through conventional treatment processes can meet the national standards. However, due to the seasonal organic pollution of the water source seriously affects the quality of the water supply, the effluent after the conventional water supply treatment process has an earthy smell, the chroma exceeds the standard, and the organic content (permanganate index CODmn) is 5-8mg / L.
[0023] In order to improve the water quality, powdered activated carbon is deployed online and water treatment method is added, and powdered activated carbon is added to the front end of the flocculation tank of the conventional water suppl...
Embodiment 2
[0026] Example 2: "Pollution emergency type": the dosing system taking powdered activated carbon as an example is applied to the emergency treatment and disposal of environmental pollution accidents at water intakes in water sources.
[0027] Basic situation of a water supply plant in a city: the daily water supply of the plant is 40×10 4 m 3 Around / d, the water is taken from the river flowing through the city. Because the upper reaches of the river have built many large industrial zones along the river, some of them belong to hazardous chemical production enterprises and petrochemical enterprises.
[0028] In order to build an emergency water quality treatment device at the water intake of the water plant to deal with possible water pollution at the intake caused by ship transportation and upstream enterprise accidents, the method of online deployment and dosing of powdered activated carbon is chosen to provide rapid and large-dose powder dry solid dosing response Water pol...
Embodiment 3
[0031] Example 3: "combination of peacetime and wartime": powdered activated carbon on-line deployment and dosing methods are simultaneously applied to the emergency treatment of water pollution in water sources and the improvement of water quality in water supply plants.
[0032] Basic situation of a water supply plant in a city: the daily water supply of the plant is 10×10 4 m 3 Around / d, the water is taken from the river flowing through the city. Because the upper reaches of the river have built many large industrial zones along the river, some of them belong to hazardous chemical production enterprises and petrochemical enterprises. At the same time, due to the discharge of domestic pollution sources, agricultural non-point sources, and industrial pollution sources, the water quality of rivers presents seasonal organic pollution characteristics, and there is even a tendency of algae outbreaks in some years.
[0033] In order to improve the water quality of the regular wa...
