- Abstract:
- Based on the real-time monitoring of discharge sludge solid content by installing a pipe-type microwave transmitter on the sludge discharge pipe of the sedimentation tank and the concentration tank, the discharge control of sludge with relatively high concentration is realized, and the discharge of sludge water is reduced. Thus, the operation and treatment load of sludge discharge pump and sludge dehydrator are optimized, the systematic operation efficiency of sewage treatment plant is improved, and the operation cost is reduced. The empirical study proves that the sludge discharge optimization system can effectively reduce the operation time of sludge pump and sludge dehydrator by over 25% based on the precise control of sludge discharge volume. Moreover, the dosage of flocculants with higher cost can be greatly reduced by 50.5%, and thus reducing both the operation cost and carbon emission of sewage treatment plant.
