摘要
调蓄池作为水环境综合整治的重要手段之一,可兼具调蓄溢流污水及初期雨水等功能,提高城市水环境抗冲击能力,保障流域水环境和水安全。以深圳市鹿丹村调蓄池为例,在保障调蓄功能的前提下,通过对原池体进行优化提升设计,增加搅拌和曝气设施使其集曝气、沉淀工序于一体,形成缺氧-好氧-沉淀分时段廊道交替运行的三沟式氧化沟工艺,并增设配套的生物除臭及底泥抽取等设施。作为污水处理厂改扩建临时保障处理设施,解决临近水厂提标改造期间旱、雨季污水处理缺口问题。
As one of the important means of comprehensive improvement of the water environment,stormwater retention tanks reduce the peak flow of floods,improve resilience of the urban water environment,and ensure the water environment and water safety within the watershed.This article takes the stormwater retention tanks in Ludan village,Shenzhen as an example.On the premise of ensuring the storage function,by optimizing the design of the original tank body,adding stirring and aeration facilities to integrate the aeration and sedimentation processes,"anoxicaerobic-sedimentation"triple oxidation ditch process that runs alternately in corridors,and adds biological deodorization and dewatering sludge treatment and disposal design.As a temporary protection and treatment facility for wastewater treatment plants expansion,solving the wastewater treatment issue in the dry and rain seasons during renovation.
