Ningxia's largest papermaking pollution control project was put into operation a few days ago

Ningxia Meili Paper Co., Ltd. alkali recovery project, the largest papermaking pollution control project in Ningxia, was put into operation a few days ago. It is estimated that 5.9 million tons of papermaking black liquor can be directly discharged into the Yellow River every year, and the industrial wastewater pollution load in Ningxia section of the Yellow River will be reduced by 17%

paper making industry is the dominant industry in Ningxia. Relying on the rich wheat straw resources in the Yellow River irrigation area, the autonomous region has successively established 40 straw pulp and paper-making enterprises, but due to the lack of necessary sewage treatment facilities, it has become the main pollution source in Ningxia section of the Yellow River. It is understood that at present, there are only 21 paper-making enterprises above Designated Size in Ningxia, which directly discharge 35million tons of industrial wastewater exceeding the standard into the Yellow River every year, of which Ningxia Meili Paper Co., Ltd. discharges 20% of the total sewage discharge into the Yellow River every year

it is understood that Ningxia plays a major leading role in the overall and long-term development of China's economy and society. Meili Paper Co., Ltd. has invested more than 170million yuan to build an alkali recovery environmental protection and energy saving project since October 1997. After the alkali recovery project is put into operation, it can not only reduce the pollution load of the enterprise by 85%, but also regularly check the transmission of the sprocket every year. However, 12000 tons of caustic soda are recovered in the trial work
