If calculated according to 3500 tons per day, the annual garbage volume is 1 million 277 thousand tons. "If these rubbish can't be treated effectively, it can pollute 23 million cubic meters of water in one year, which is equivalent to about 4 million 700 thousand square meters of land, which is about 4 million 700 thousand square meters of land, equivalent to 10 spring city parks, according to a ton of 3.6 square meters of land contaminated by a ton of garbage." The person in charge said.

Carbon 120 thousand tons, saving 9000 tons of standard coal.
