Project Background: The company discharges approximately 300 tons of production wastewater daily. Individual advanced treatment is costly, while downstream wastewater treatment plants suffer from insufficient influent carbon sources, requiring an additional expenditure of several million yuan annually to purchase glucose to maintain microbial activity.
Solution Advantages:
Innovative Model Advantage: This innovative "negotiated discharge" model utilizes papermaking wastewater as a high-quality carbon source to supplement the downstream wastewater treatment plant's biological treatment system. This eliminates the need for the company to build its own advanced treatment facilities, saving over 8 million yuan in equipment investment.
Cost Synergy Advantage: The company saves over 1 million yuan annually in wastewater treatment costs, while the downstream wastewater treatment plant reduces glucose procurement costs by over 1.5 million yuan annually. Simultaneously, the overall regional carbon emissions are reduced by approximately 1,000 tons, achieving resource complementarity between enterprises and synergistic efficiency in regional pollution reduction and carbon reduction.
Compliance Guarantee Advantage: Real-time online monitoring of water quality data between both parties ensures a wastewater carbon source utilization rate of over 95%, fully complying with environmental protection department emission requirements and eliminating compliance risks.
