News feedback: Huang Jiang can finally produce clean products

Subject matter: In 2002, our reporter investigated the environmental pollution of yellow ginger processing companies in the middle and upper reaches of the Hanjiang River, a water source in the middle line of the South-to-North Water Transfer Project. In this paper, we published “Development and Environmental Protection: Double-edged swords for difficult dances.†In 2004, this reporter made a return visit and found that the pollution in the Han River was still serious. This newspaper published on January 17, 2005, “The Dilemma of the Han River: Downstream Pollutants for Pollutant Control in the Upper Reaches of the Han Riverâ€. Causes of Pollution Rebound."
To solve the problems of the backward production process of many diosgenin processing companies in Hubei and Shaanxi, and the serious pollution of wastewater discharge to the water source area of ​​the middle line of the South-to-North Water Diversion Project, the government has always been highly valued by local people's expectations. Recently, the reporter from the Japan Daily News once again paid a return visit to the production of yellow saponin and found that through the unremitting efforts of the environmental protection department, Huang Jiang processing enterprises and related scientific research institutions, the diosgenin can finally be produced cleanly.
In Hubei, Huang Jiang is an important economic crop for farmers in northwestern Hubei to shake off poverty and become rich. However, the traditional turmeric production technology is backward, the utilization rate of turmeric is extremely low, and the contained starch, cellulose and acid used for processing are all discharged, and the content of COD and BOD in waste water is as high as 30000 mg/L, which is equivalent to that of papermaking wastewater. More than 10 times, the existing pollution control process has high operating costs and it is extremely difficult to meet the discharge standards. Shiyan City and other parts of the Han River upstream turmeric processing company's wastewater, eventually discharged to the Han River, into the Danjiangkou Reservoir, threatening the South-North Water Transfer midline water security. Governments at all levels attach great importance to this, and the leaders of Hubei Province have repeatedly stated that they must solve the pollution problem of Huang Jiang industry as soon as possible.
Guo Xiangfen, a professor at the China University of Geosciences, who once served as the deputy governor of science and technology in the county of Shiyan City, determined to start with technological innovation and solve this problem. She analyzed the composition of turmeric and found a new method - physical separation. The key to this idea is to separate the fiber and starch from the yellow ginger. In the laboratory of Kangdi Pharmaceutical Factory in Shexian County, Guo Xiangfen finally succeeded in isolating turmeric starch using ultrasonic methods. In September 2003, a brand-new process route “Direct Separation Production of Huangjiang New Technology†was born.
The technology has been continuously improved through the enlargement of the company. On August 21, 2005, Geda Environmental Protection Technology Co., Ltd. of the University of Geological Sciences and the Zhuxi County People's Government of Shiyan City signed the Contract for the Construction of a Demonstration Project for Clean Production of Sanjiang-saponin. At the same time, the first “industrial technology for the production of turmeric by direct separation†was completed and put into trial production at Yuankang Pharmaceutical Company in Zhangwan District, Shiyan City. Companies and environmental protection agencies that use this technology believe that the success of this technology is a milestone, a revolution in the ginger processing industry, and has three major advantages over traditional methods:
One is to solve the problem of waste water pollution from yellow ginger processing. Responsible comrades of the Zhuxi County Environmental Protection Bureau told the reporter that after the completion of production of the demonstration project of sanjiang saponin cleaner production, the amount of wastewater per ton of saponin hydrolysate was reduced from the previous 800 to 1000 tons to 70 tons; Hubei Provincial Environmental Protection Supervision Corps The person in charge told the reporter that the application of this technology to enterprises can effectively reduce the discharge of yellow ginger wastewater, which is of great significance for maintaining the water quality of the Han River.
Second, Huang Jiang resources are fully utilized. For each enterprise producing 100 tons of saponin, this technology can recover 1,500 tons of fiber and 1,200 tons of starch. The planting area of ​​600,000 acres of yellow ginger is used to recover 300,000 mu of grain.
The third is to achieve the healthy development of the ginger industry. Some ginger processing companies shut down due to pollution can use this technology to resume production. A person in charge of the Shiyan City Government Office told the reporter that the city will give full play to the role of this patented technology, industrialize the technology as soon as possible, and promote the rapid development of the city's yellow ginger industry.
