火电厂发电水耗偏高原因分析及解决措施

Cause Analysis and Countermeasures of Higher Water Consumption in Thermal Power Plant

内蒙古国华呼伦贝尔发电有限公司2台空冷机组发电水耗长期偏高,废水无法完全回收利用,废水外排既造成水资源浪费,也易导致环境污染。通过对全厂水平衡及废水回用开展分析研究,实施精处理高低盐废水分离改造、除铁除锰过滤器反洗排水改造等措施,建立全厂水网在线监测统计系统,使公司发电水耗由0.32 kg/kWh降至0.16 kg/kWh,实现了全厂各类废水分类、分质回收利用,达到了降低生产用水成本的目的。

Inner Mongolia Guohua Hulun Buir Power Generation Co.,Ltd. 2 sets of air-cooled unit power generation water cost was long-term high, waste water can not be fully recycled, waste water effluent that is caused by waste water, but also easily lead to environmental pollution. Through the water balance and wastewater reuse analysis, the implementation of fine salt treatment of high and low waste water separation and transformation, in addition to iron and manganese filter backwash drainage and other measures to establish the whole plant water network on-line monitoring and statistical system, the company water consumption rate decend from 0.32 kg/kWh to 0.16 kg/kWh, the plant achieves all types of wastewater classification, quality of recycling, achieves the purpose of reducing production costs of water.
