All the muddy water produced in the process of sand and stone production is pumped into the concentration tank for rapid precipitation, and the clean water after high pressure desliming is recycled.

On August 30, the observation group of the on-site promotion meeting of the unified mining and operation of river sand and gravel in Gansu Province was in Dangchang. Ye Weimin, deputy director of the River and Lake Protection Center of the Ministry of Water Resources, Zhang Xinghong, deputy director of the River and Lake Administration Bureau of the Yellow River Commission, Xiang Jihong, deputy director of the River Sand Mining and River and Lake Administration Bureau of the Yangtze River Commission, Zhang Bo, engineer of the River and Lake Protection Center of the Ministry of Water Resources, Cheng Jiangfen, deputy director of the Provincial Water Resources Department, and heads of relevant departments and units directly under the provincial level, and relevant heads of water bureaus of cities, prefectures, counties and districts.

The delegation fully affirmed the development and operation of Nanhe Non-metallic Mineral Industrial Park.

It is understood that the Nanhe Non-metallic Mineral Industrial Park in Dangchang County is the first state-owned standardized non-metallic mineral industrial park in Dangchang County. In order to realize the ecological beautiful picture scroll of "clear water, smooth river, stable bank and beautiful scenery", the industrial park constructs an ecological environmental protection filter pressing system according to the standardized construction scale, which quickly precipitates all the muddy water produced in the sand and gravel production process into the concentration tank, recycles the clean water after high pressure desliming, and uses the separated mud for brick making, landscape greening and river leveling. It truly realizes the production standard of "closed, factory, ecological and high environmental protection". At the same time, by means of "civil air defense + technical defense", on the premise of fully implementing the river and lake length system, we have raised funds to build a smart river and lake supervision platform, installed 230 remote monitoring videos in Minjiang River and its tributaries, realized full coverage of river supervision, improved the level of flood control and disaster reduction monitoring and early warning, and found a way of ecological protection and economic development. Sustained, stable, healthy and orderly development of the county's economy and society.
