Analysis and Countermeasures: Oil Pollution Causing Pipeline Blockage and Urban Waterlogging

Abstract

In recent years, the problem of urban waterlogging has become more and more serious during the process of rapidly advancing urbanization in China, including the world climate change, low-level standards of design and construction of rainwater canals and the increase of hard coverage, leading to different severe factors. Meanwhile, the urban water-logging is becoming even serious due to the blockage, and hetero-pipe insertion of drainage pipe. Another major cause of pipeline blockage, namely to be massive oil in the kitchen waste, was further investigated. Furthermore, foreign advanced measures should be reasonably introduced. In terms of urban construction, large-capacity underground storage system and a new type of rainwater treatment system which is promoted in Germany, namely "watershed seepage canal system", were adopted. The waste classification management and oil-water separator could make contributions to source control. The combination of municipal systems and technology can effectively solve the problems of blockage in the urban drainage system and urban water-logging.
