摘要

摘要: 李村河流域是青岛市中心城区流域面积最大的河流系统和过城河道。由于基础设施薄弱、城市面源污染突出、长效机制不健全、河道生态稳定性差、沿岸居民环保意识弱等,导致李村河常年黑臭。自2016年以来,从控源截污、内源治理、生态修复、活水保质和长效机制5个层面对李村河进行综合整治,主要措施包括污水处理厂的提标改造、雨污分流、垃圾清运、淤泥清淤、生态修复及补水、建立河道管理机制等。在生态补水及调蓄整治过程中,通过结合管线非开挖定向钻穿越技术,创新性地对李村河进行再生水管道河底非开挖铺设。通过流域综合整治,消除了水体黑臭现象,将李村河打造成了常年有水、水清岸绿,集休闲健身、生态调节等功能为一体的生态景观廊道。

Abstract: The Licun River basin was the largest river system in the downtown area of Qingdao and the largest river crossing the city. The weak infrastructure, prominent urban non-point source pollution, inadequate long-term mechanism, low ecological stability of the river channel and poor environmental awareness of residents along the river had caused black and odorous problem in the Licun River all the year round. Since 2016, the Licun River had been comprehensively rehabilitated from five aspects, i.e. source control and pollution interception, endogenous pollution control, ecological restoration, maintaining the living water quality, and long-term management mechanism. The main measures included upgrading of sewage treatment plants, diversion of rainwater and sewage pipelines, garbage removal and transportation, silt dredging, ecological restoration and water replenishment, and establishment of river management mechanism, etc. In the process of ecological water replenishment and water regulation and storage of the Licun River, laying of reclaimed water pipeline without excavation at the bottom of the Licun River was innovatively carried out, by incorporating the trenchless directional drilling crossing technology of the pipeline. After the regulation of Licun River basin, the black and odorous water body was eliminated, and the Licun River had been built into an ecological landscape corridor integrating the functions of leisure, fitness and ecological adjustment, with perennial water, clean water and green banks.
