一体化水处理装置及其控制系统设计

相比传统水处理装置,一体化水处理装置因其占地小、能耗低、安装便捷等优点而具有一定的应用前景。采用双向旋流混凝、絮凝设计,通过改进动水模型和斜板结构,可有效提高处理能力,改善出水水质。针对对水处理设备主要故障,提出对重点部位、重要参数增设无线传感节点,构成无线监测预警系统以提高系统可靠性,降低故障率。试验结果表明,一体化水处理装置不仅可有效去除废水中的盐类和COD,而且出水水质大大提高。最终出水浊度小于(2~5)NTU,COD去除率为(50~75)%,达到了电力、化工等行业的循环冷却补给水的回用水水质要求。

Design of Integrated Water Clarifier and its Control System

Compared with the traditional water treatment equipment,the integrated water clarifier has certain advantages and application prospect because of its small footprint,low energy consumption,easy installation.It adopts bi-directional hydrocyclone coagulation,flocculation design.Through improving the dynamic water model and the inclined plate structure handling capacity and the effluent quality are effectively improved.For the main faults of water treatment equipment,its key parts and important parameters with wireless sensor node are provided,which constitute a wireless monitoring and warning system in order to improve the system reliability and reduce the failure rate.Experimental results show that the integrated water clarifier not only remove the salts and COD in waste water efficiently,but also greatly improve the water quality.The final turbidity of permeate is less than(2~5)NTU with COD removal rate of(50~75)%,which can be reused as cooling water in electric power and chemical industry.
