摘　　要：针对当前大多数城市生活污水排水工程对lngdp贡献度低的问题,提出基于PVAR模型的生活污水排水工程治理方法研究。改建污水排水管网,结合城市道路具体分布,设置污水泵站,采用截流式合流制排水方法,在截流管道上设立溢流井,计算管道排水量,合理选择排水管道材料,根据PVAR模型,分析污水治理对经济效益的影响,利用组内均值差分法,去除时间效应产生的随机变量,得到广义矩估计结果,实施排水工程。实验结果表明,采用PVAR模型的生活污水排水工程治理方法对lngdp的贡献度远高于传统方法。In view of the low contribution of most domestic sewage drainage projects to LNGDP,a PVAR model-based treatment method for domestic sewage drainage projects is proposed.The study rebuilt sewage drainage pipe network.Combined with the distribution of city road,it set up the sewage pumping station.Using confluence of intercepting drainage method,it set up wells on the intercepting pipe.Through pipeline displacement calculation,it elected reasonable drainage pipe material.According to PVAR model,the effect of sewage disposal of economic benefit were analyzed using the mean difference method in the group.By removing the time effect of random variables,it generalized moment estimation results.The experimental results show that the domestic sewage drainage engineering treatment method using PVAR model contributes much more to LNGDP than the traditional method.
