Based on our successful experience in similar wastewater and sludge treatment, the deep sludge dewatering and drying technology combining sludge chemical modification and plate and frame dewatering is adopted to directly reduce the water content of sludge from 95% to below 60%, so as to achieve "reduction, stabilization and harmlessness" of sludge

The first industrial wastewater treatment plant with high concentration fluorine wastewater recycling and utilization in China realizes water recycling and replaces high-quality drinking water resources, effectively solves the problems of large amount of industrial wastewater, large water quality change, high ionic substances and poor biodegradability in the photovoltaic industry, and provides solid guarantee for promoting the green, low-carbon and high-quality development of the photovoltaic industry in Yiwu.

Piling sludge, tunnel sludge, etc. are the main solid wastes in the construction process. The sludge has high water content, high transportation cost and is easy to cause secondary pollution. Therefore, it is necessary to carry out on-site dehydration treatment to greatly reduce the cost and effectively improve the daily treatment capacity.

High-efficiency quick-opening membrane filter press produced by Xingyuan Environmental Protection Co., Ltd. is widely used in wastewater treatment of aggregate production in Zhejiang Jiaotou (Zhaoqing) Co., Ltd., Yangxinwa Stone Building Materials Co., Ltd., Qingyuan Xianhe (Guangdong North Region) Co., Ltd., Dazhou Zhengxiang New Material Co., Ltd. and Juhua New Material Co., Ltd. The water content after membrane pressing is lower than 25%. The treated mud cake can be backfilled and re-greened in the mine, and the filtrate can be returned to the vibrating screen for recycling, so as to realize cyclic production.
