摘要
Abstract
Extraneous water infiltration increases the operational load of sewage pipe networks and wastewater treat-ment plants,and may lead to manhole overflow and severe environmental pollution under extreme conditions.Tak-ing the sewage pipe network of a county in southern China as the research object,real-time data including rainfall,flow rate and water level were collected based on the internet of things(IoT).The minimum night flow method was adopted to analyze extraneous water infiltration in the research area during dry weather.Using typical dry-weather sewage flow as the baseline,variations of extraneous water inflow and manhole water level in the same area under different rainfall conditions were further analyzed.The research results show that the dry-weather extraneous water infiltration rate of all zones exceeds 70%,indicating severe extraneous water infiltration.Under specific rainfall conditions,the proportions of extraneous water inflow at four monitoring points are 64.69%,56.01%,62.26%and 45.97%,respectively.Only monitoring point 4 suffers moderate extraneous water infiltration,while the others expe-rience severe infiltration.Meanwhile,rainfall-induced inflow contributes to increased pipeline flow and rising man-hole water levels.Both indicators are positively correlated with rainfall intensity and rainfall duration,and manhole overflow may occur in serious cases.Combined with the case analysis,the monitoring of extraneous water infiltra-tion,rainfall inflow and sewer overflow can rely on the IoT platform to establish a management system featuring real-time monitoring,analytical evaluation and alarm response,so as to continuously promote the control of extraneous water infiltration and sewer overflow.关键词
