摘要
为解决污水处理厂的邻避效应,以及充分利用地上空间进行协同开发,江苏省某规模为20万m^(3)/d的污水处理厂采用了全地下、集约式的布置形式。文章总结了此座全地下污水处理厂在设计中采取的安全设计措施,先从地下箱体的消防、防淹排涝、厂区停电、药品泄漏4个方面分析了污水处理厂面临的安全风险;针对各方面风险从设计原则、思路到设计方案进行了介绍。箱体消防从总图运输、火灾报警系统、消防设施、安全疏散、箱体照明等方面进行了分析;防淹排涝从汛期应对措施及箱体内排出不及时溢水进行设计;厂区停电从进出水环节、应急电源及自控仪表等方面进行考虑;药品泄漏同时兼顾了地下加药间的药品安全措施,以及事故时排水系统如何处理不达标出水的方案。该项目也结合了已建成地下污水处理厂的设计思路及运营经验,对设计细节进行了优化,总结工程特点,为其他类似工程提供借鉴。
In order to solve the neighboring WWTP effect of wastewater treatment plants(WWTPs)and take full advantage of the above-ground space for collaborative development,a with a scale of 200000 m^(3)/d in Jiangsu Province adopts the method of underground and intensive design.This paper summarizes the safety countermeasures adopted in the design of this underground WWTP.In the first,the safety risks faced by the WWTP are analyzed from the aspects of fire protection,flood prevention and drainage,power outage in the plant area and drug leakage.In view of each aspect of risk,the design principles,concepts and design schemes are introduced.The fire protection of the structural box is analyzed from the perspectives of general layout transportation,fire alarm system,fire protection facilities,safe evacuation,lighting and so forth.Flood control and drainage are designed from the flood season corresponding measures and the discharge is not timely overflow.The power outage in the underground plant area is considered from three aspects,water inlet and outlet,emergency power supply and automatic control instrument.The drug safety measures of the underground dosing room and how the drainage system prevents the discharge of substandard water during the accident are both taken into account from the aspect of drug leakage.In the meantime,combined with the design schemes,operation experiences of some built underground WWTPs,the design details are optimized,and the engineering characteristics are summarized to provide references for other similar projects.
