摘要
以辽宁工程技术大学玉龙校区教师公寓小区雨水回用为研究对象,通过对小区内屋面、道路及绿地的可集流雨水量进行计算,并对不同区域的雨水水质进行取样监测,得到了整个教师公寓小区雨水的径流特征和水质特性;结合小区内雨水综合利用途径,通过水量平衡计算,确定了雨水的集流范围和集流方式;在此基础上,进行实验室混凝试验,结果表明:采用PAC作为混凝剂,投加量为40mg/L,实验参数为中速150r/min搅拌3min、慢速50r/min搅拌10min,然后静置沉淀15min的条件下,雨水浊度去除率为91.3%、COD去除率为61.2%、NH3—N去除率为29.3%,依据上述实验结果给出了参考处理工艺,出水水质满足城市杂用水水质标准。研究结果可为北方缺水型城市小区雨水综合利用提供有益的参考价值。
The rainwater in Liaoning Technical University Yulong school teachers' apartment was selected as the research object.By calculating the rainwater volume in the position of the roofing,the road and the grassland and the monitoring result of water quality in different area,we get the water runoff characteristics and water quality characteristics in the whole teachers' apartment.Associated the comprehensive utilization way of rainwater in this apartment,we work out the rainwater harvesting scope and method and conduct a coagulation test based on the above.Select PAC as coagulant and the dosage is 40mg/L.Stir with medium speed 150r/min and last 3min or low speed 50r/min 15 min,then let stand for 15 min.The result show that under above condition the removal rate of rainwater turbidity is 91.3%,the removal rate of COD is 61.2%and the removal rate of NH3-N is 29.3%.The reference treatment process is given according to the above result and the water quality meets the water quality standard of the city.The results could provide valuable reference for comprehensive utilization of rainwater in the north water shortage city.
