Description

背景技术 Background technique
近5年来，高效沉淀池在国内供水和污水处理领域应用较多。尤其是在大连马栏河污水处理厂的成功应用，使得该技术引起了广泛关注。目前，国内已建项目有几十座，但运行效果差异很大。高效沉淀技术实际上是机械混凝、絮凝和斜管(板)沉淀技术的结合，与常规水力混凝和絮凝相比，由于强化了混凝和絮凝的效果，进而提高了斜管(板)沉淀池的沉淀效率，尤其是对原水中的悬浮物和非溶解性有机污染物具有较好的去除效果。因此，该工艺被广泛用于供水及污水的预处理和污水的深度处理。 In the past five years, high-efficiency sedimentation tanks have been widely used in domestic water supply and sewage treatment fields. Especially in the successful application of Dalian Malanhe Sewage Treatment Plant, this technology has attracted widespread attention. At present, there are dozens of domestic projects that have been built, but the operating results vary greatly. High-efficiency sedimentation technology is actually a combination of mechanical coagulation, flocculation and inclined tube (plate) sedimentation technology. Compared with conventional hydraulic coagulation and flocculation, due to the enhanced effect of coagulation and flocculation, the inclined tube (plate) is improved. The sedimentation efficiency of the sedimentation tank, especially for the removal of suspended solids and insoluble organic pollutants in the raw water, has a good effect. Therefore, this process is widely used in the pretreatment of water supply and sewage and the advanced treatment of sewage.
但是目前采用的高密沉淀及时均存在加密载体密度不够，导致沉淀池占地面积减少量有限，且加密载体损失严重，增加了管理难度和运行成本。因此开发研究工艺简单、技术可靠、管理方便、经济合理的新工艺和新设备，仍是污水加密沉淀处理技术利用的重要课题。 However, the density of the encryption carrier is not enough in the high-density sedimentation currently used, which leads to a limited reduction in the area of the sedimentation tank, and the loss of the encryption carrier is serious, which increases the difficulty of management and operating costs. Therefore, the development and research of new processes and new equipment with simple process, reliable technology, convenient management, and economical rationality is still an important topic for the utilization of sewage encryption sedimentation treatment technology.
