2. Brief description of technology

The sisal fiber processing process requires clean water to wash the hemp fiber, and the washing process produces organic wastewater with high COD. This technology uses a biocatalyst prepared by special enzyme-producing microbial strains to treat sisal wastewater. The biocatalyst decomposes inhibitors in wastewater and quickly precipitates saponin. Through the adoption of technology, sisal wastewater can simultaneously obtain saponin raw materials and clean water. The entire process can complete wastewater treatment within 48 hours. The saponin obtained by processing is the basic raw material for the synthesis of steroid hormone drugs. Reclaimed water can be reused in the sisal fiber processing process, saving water resources.

3. technical information

COD is degraded and reclaimed water is reused. Separation of saponin.

4. comprehensive benefits

The sisal fiber processing process produces a large amount of high-COD (chemical oxygen demand) organic wastewater, with a COD value reaching 20,000 milligrams per liter. The high-COD organic wastewater cannot be treated by general environmental protection processes. At the same time, wastewater contains saponin, which is a raw material for synthesizing steroid hormone drugs. Direct discharge results in waste of resources. The existing sisal wastewater treatment method is to treat it by drying, and the drying process lasts for 15 to 40 days. The water is dried by solar evaporation in a large drying yard, thereby concentrating to obtain saponin. The drying process emits a foul smell, and the drying waste water will also penetrate into the ground, causing water pollution. The technology adopts special enzyme-producing microorganisms to decompose and destroy inhibitors in wastewater, promote and accelerate the treatment process of microorganisms on wastewater, and treat wastewater to COD 200 mg/L within 48 hours to achieve the purity of reclaimed water. During the treatment process, saponin precipitation is obtained simultaneously. Saponin and clean water are simultaneously obtained in one treatment process. This technology does not require a drying yard and does not produce odorous gases. There is no discharge or leakage of high-COD wastewater. The generated water can be reused to save water resources. The obtained saponin is a raw material for the manufacturing of drugs and can be further developed to obtain higher benefits and income.
