About the Actual Application of the Precision Casting System of Carbon Source Pharmaceuticals in Sewage Plants

摘要: 本文通过碳源药剂精准投加系统单点位控制与污水厂传统人工控制加药量对比、碳源药剂精准投加系统单点位控制与双点位控制对比，在安徽某污水厂进行生产性对比实验，来研究碳源药剂精准投加系统在实际应用过程中的优势。结果表明：碳源药剂精准加药系统单点位相较人工控制加药量的方式，去除单位总氮可降低0.51 kg碳源，脱氮成本降低了0.59元/kg，吨水成本降低了8.33%；碳源药剂精准加药系统双点位控制相较单点位控制方式，去除单位总氮可降低1.33kg碳源，脱氮成本降低了1.54元/kg，吨水成本降低了14.29%。碳源药剂精准投加系统可在保证污水厂出水稳定达标的前提下，实现水厂的降本增效，具有较高的市场推广价值。

Abstract: This paper studies the advantages of carbon source pharmaceutical precision dosing system in the actual application process by comparing the single-point control with the traditional manual control dosing volume of the sewage plant, the single-point control and two-point control of the carbon source pharmaceutical precision casting system, and carrying out the productive comparison experiment in a sewage plant in Anhui. The results showed that the single-point phase of carbon source pharmaceutical system could reduce the total nitrogen per unit by 0.51 kg, the cost of ni-trogen removal by 0.59 yuan/kg, and the cost of tons of water by 8.33%. The two-point control method of carbon source pharmaceutical precision dosing system can reduce the total nitrogen per unit by 1.33 kg, the cost of de nitriding by 1.54 yuan/kg and the cost of tons of water by 14.29%. Carbon-source pharmaceutical precision casting system can ensure to achieve cost reduction and efficiency increasing of the sewage plant on the premise of the outlet is stable and up to the standard.
