The company employs advanced technology, leveraging local raw material advantages, primarily processing and extracting Scutellaria baicalensis and Lonicera japonica.
The pollutants generated during the production process mainly include wastewater from traditional Chinese medicine extraction, followed by a small amount of waste gas and noise. The company has implemented corresponding treatment measures to meet the standards for emissions. The wastewater from the traditional Chinese medicine extraction process has a heavy pollution load, containing acids and other difficultly biodegradable organic substances. The company currently has a wastewater treatment facility, but due to the increased scale of production and water volume, the existing process is no longer sufficient. Therefore, the company urgently needs to construct a larger production wastewater treatment facility. The quality and volume of the traditional Chinese medicine extraction water vary significantly, with high COD levels fluctuating between 5,000 to 20,000, and good biodegradability. Recognizing the importance of environmental protection, the company intends to adopt effective pollution prevention measures in accordance with the requirements of environmental protection units in Shandong Province. It plans to invest in wastewater treatment, with the wastewater treatment station processing 500 cubic meters of wastewater per day.
Under the authorization of the company, our unit has specially prepared the following preliminary design plan for the wastewater treatment project and estimated the investment for the project, for the review and consideration of the company's leadership and environmental protection department. As an important component of the enterprise's infrastructure and a critical link in water pollution control, the construction and operation of this wastewater treatment project are of great significance. Given that the construction and operation of the wastewater treatment project are not only costly but also subject to various constraints and influences, the optimal selection of the treatment process is crucial for the performance of the treatment plant and cost reduction. Therefore, it is necessary to choose a practical and economically reasonable solution based on established standards and general principles, starting from the perspective of overall optimization, combining the design scale, characteristics of the wastewater quality, and the local actual conditions and requirements. After technical and economic comparisons, the overall process scheme and implementation method are selected.
