摘　　要：电子电路行业在生产过程中会产生废水,需要进行处理。在废水的处理过程中,需要大量使用碱类药剂来调节pH值。为降低碱类药剂成本,业内广泛使用复合碱替代液碱来处理废水。研究了含钙成分的碱类应用于废水处理后,对废水系统运行成本、废水处理效果、废水污泥产量及设备设施结垢的影响。分析表明,使用复合碱处理废水有助于节约成本、稳定废水处理效果,但需结合现场设备实际使用情况合理使用。The electronic circuit industry generates wastewater during production,and the wastewater requires treatment.In the process of wastewater treatment,it is necessary to use a large amount of alkaline agents to regulate the acidity and alkalinity(p H).In order to reduce the cost of alkali chemicals,complex alkali(calcium-containing alkali) is widely used in the industry instead of liquid alkali for wastewater treatment.In this paper,the effects of alkali containing calcium applied to wastewater treatment on the operating cost of wastewater system,wastewater treatment effect,wastewater sludge production and equipment scaling are studied.The analysis shows that the use of complex alkali to treat the wastewater is helpful to save the cost and stabilize the wastewater treatment effect,but it should be used reasonably in combination with the actual use of on-site equipment.
