In particular, 283 industrial parks across the country are "marinated" into the environment of 550,000 cubic meters of wastewater per day. Unfortunately, of the 615 industrial clusters, only 5% have wastewater treatment systems, and more than 500 facilities have outdated production technologies. Not to mention, 5,000 businesses, 4,500 craft villages, 13,500 medical facilities generate tens of tons of waste into the environment.
