摘要

采用“混凝沉淀-人工湿地”工艺处理绿色建筑优质杂排水

混凝沉淀预处理的正交试验结果表明

出水BOD5与容积负荷(Nv)、温度(T)、PAC加药量(ρ)之间符合一次线性回归正交方程：BOD5＝2.05 Nv-0.41T-0.82ρ+38.9.人工湿地后处理的正交试验结果表明

出水BOD5与人工湿地面积负荷(NA)、温度(T)符合一次线性回归正交方程：BOD5＝NA-0.32T+12.2.以试验结果的2项回归正交方程为基础

结合绿色建筑不同季节的中水用水

Abstract

Orthogonal experiments were carried out for high grade gray water treated by combinational technique of coagulation sedimentation and constructed wetland. With the orthogonal experiment of coagulation sedimentation pretreatment

it is shown that the regression equations relating to effluent BOD5

cubage loads(Nv)

temperature(T) and PAC addition dosage(ρ) is BOD5=2.05Nv-0.41T-0.82ρ+38.9. For the orthogonal experiment of constructed wetland posttreatment

it is shown that the regression equations relating to effluent BOD5

cubage loads(NA)

and temperature(T) is BOD5=1 190 NA-0.32T+12.2. Based on the two orthogonal regression equations

combined with reclaimed water quantity requirements in different seasons in buildings

an investment optimization model of combinational technique was established. According to the model

the reasonable scale of the reclaimed water treatment systems can be determined and treatment efficacy can be well predicted.
