Recently, according to the survey data of the Ministry of Water Resources, more than 80% of groundwater can not be directly drinkable, and the overexploitation is serious, especially in Hebei. The main causes of groundwater pollution are the infiltration of heavy metals and toxic substances into groundwater. So what is the cause of heavy metals and toxic substances exceeding the standard?

The main reason is the pollution of agricultural drugs, industrial wastes and garbage infiltration liquor. These pollutants permeate into shallow groundwater with rainwater, causing groundwater pollution.

This situation shows that water treatment is more needed in Hebei area, and it also gives an opportunity for integrated MBR membrane wastewater treatment plants to develop, especially in the treatment of heavy metals and toxic substances.
