利用城市污水源的大型集中供热管网补水及补热技术分析

Analysis of Water Supplement and Heat Supplement Technology for Large-Scale Central Heating Pipe Network Using Urban Sewage Sources

为了解决城市污水问题,研究了利用城市污水源的大型集中供热管网补水及补热技术的价值。采用统计法,分析一个大型供热公司每个采暖季用水量,以及北方地区100万级城市日均污水处理量平均量,并以此为基础开展项目。经统计,北方地区100万级城市日均污水处理量约为25万t,一个大型供热公司每个采暖季用水约为150万t。采用处理后的中水作为热网补水,对供热公司大网安全运行起到支撑作用。同时起到大网平衡的调节作用,产生较好的经济影响和社会效益。

Purpose In order to better solve the problem of urban sewage,we are now exploring the value of water supply and heat supply technology for large-scale central heating pipelines using urban sewage sources.Methods Using statistical methods,analyze the water consumption of a large heating company in each heating season and the average daily sewage treatment volume of 1 million cities in the northern region,and carry out the project based on this.Results According to statistics,the average daily sewage treatment volume of 1 million cities in the northern region is about 250,000 tons.A large heating company uses about 1.5 million tons of water per heating season.Conclusion The use of treated reclaimed water as supplementary water for the heating network can support the safe operation of the heating company’s large network.At the same time,it plays a role in regulating the balance of the big network,and produces better social influence and social benefits.
