某化工园区项目取水可行性计算分析

Analysis of Feasibility Calculation of Water Intake for a Chemical Industry Park Project

某化工园区项目主要取水水源石步河中型水库地表水和再生水,年取水总量为414万m^(3)。文章针对石步河水库水源进行分析论证,水库按照工业供水、生态用水供水目标不变情况下,近期灌溉面积333.33 hm^(2)时可满足热电联产供水;远期灌溉面积0.20万hm^(2)时热电联产厂缺水为114.40万m^(3),缺水部分由经过处理合格的污水处理厂再生水作为循环冷却水水源,来满足项目区生产生活用水。

The main water intake source of a chemical industry park project is surface water and reclaimed water from Shibuhe Reservoir,which is a medium size reservoir,with an annual total water intake of 4.14 million m^(3).The water source of Shibuhe Reservoir is analyzed and demonstrated in this paper.Under the condition that the water supply targets of industrial water supply and ecological water supply remain unchanged,the newly irrigated area of 333.33 hm'can meet the cogeneration water supply.When the long-term rrigation area is 0.20 million hm',the water shortage of the cogeneration plant is 1.144 million m^(3).In the water shortage part,the reclaimed water from the treated and qualified sewage treatment plant is used as the source of circulating cooling water to meet the production and domestic water consumption in the project area.
