Through research of automatic dosing system , established by determining automatic dosage in the methods of transmittance pulsation , streaming potential and mathematical model , it can be concluded that the automatic dosing system brought forward in this paper can fulfill requirements of the technics . likely , this system can also be applied for dosing of other chemicals in water plants , chemical dosing of wastewater treatment plants and other similar places 通过对采用透光率脉动、流动电位、数学模型等方法确定混凝剂投加量建立的自动配投系统的研究表明本文提出的自动配投系统能满足工艺的要求:同样该系统也适用于给水处理厂其他药剂的投加,适用于污水处理厂及其他类似场合药剂的投加。
In practice , data acquisition , computing of chemical dosage , chemical mixture and chemical dosing can be integrated organically by utilizing modern automation technology , which enables the difficult manual chemical dosing system to become an integrate equipment and makes dosing automatically realized only if the required chemical dosage is input 在实践中通过应用现代自动化技术将数据的采集、药液投加量的计算、药液的配兑及投加有机地结合在一起:使人工操作比较复杂的药液配投系统变成一套完整的设备,只用输入需要的药液投加量就能自动实现投加。
Based on the analysis of the operation control system , the improvement of the dosing system has been done . the control mode depending on the hard ware is charged to the control mode depending on software mainly . the factors that infect the control target are concerned as many as possible 把现在的以硬件实现为主的控制模式,改进为以软件为主导的综合控制模式,尽可能全面客观地把所有影响实现控制目标的因素列入控制系统作为控制因子,通过编程而尽量模拟人工智能的方法实现控制目标。
Through analyzing the domestic and foreign coagulant dosing systems concerning water treatment plant and the practical situation in china , the automatic coagulant dosing system with the core of gravitational dosing is put forward in this paper , which successfully solved the operating instability of dosing system that has always been a puzzled problem to water plants 本文在分析研究国内外有关给水处理厂的混凝剂药液配投系统的基础上,结合我国的实际情况,提出了以重力投加为核心的给水处理厂混凝剂药液自动配投系统,成功地解决了长期困扰给水处理厂投药系统运行不稳定的难题。
