A Urban Sewage Pipe Network Extension Phase Ⅱ Project Research And Design

With the continuous deepening of reform and opening up, A urban rapid economic development, A urban expanding, accelerating the pace of urbanization, rising living standards, sewage discharge volume increased year by year. Industrial production of "three wastes" discharge has serious than the environment's self-purification capacity, in particular, excessive dust pollution is serious, resulting in urban air quality as "serious" pollution level, as part of untreated urban sewage directly into the Q River, downstream of the region and pose a threat to the W River.The urban City's development objective is a modern city garden, construction of urban sewage pipe network system is to control water pollution, improve urban environmental quality and effective way, but also the construction of urban infrastructure an important part of the beautification of the city, improve the investment environment, investment and promote the coordinated development of economy A urban City, plays a very important role.The urban sewage pipe network and wastewater reuse pipe network renovation and expansion of the gradual implementation of a project on urban environmental quality the urban despite the change, but still can not meet the rapid development of urban construction.Based on the current situation and development the urban city planning, engineering solutions were designed, and the estimation and economic evaluation of investment, research and analysis of the urban sewage pipe network renovation and expansion possible the implementation of Phaseâ…¡, necessity and importance.
