【摘要】：随着经济和科学技术的发展与需求,国内大部分的油田开发已进入后期,污水的产量逐渐增多。其中,一部分废水需经过处理才能排放到地表水体中,然而由于处理不合理,排出后的污水中可能有某些污染源的含量超标,达不到国家污水排放标准,将其排放到环境中,会污染水体,危害水生植物,还可能在一些鱼和贝类体内富集而最终危害人类。所以,油田污水处理后的排放指标监测成为当前研究重点。针对目前污水排放监控方法较为复杂、不易控制的问题,提出了基于组态王的水质监控系统方案,设计了以组态王软件为基础的污水排放指标的据采集监控系统,该系统主要实现数据读取、数据报表查询、历史趋势曲线在线显示、超限报警、排放指标不达标限制排放等功能,节省了大量的人力物力。论文首先介绍了国内外油田开发所产生的污水水质监测现状及趋势,分析了传统水质监测手段的优缺点和不足,给出了油田污水排放指标监控系统的设计思想。然后根据系统监测和控制方面的要求,从系统组成、功能方面对数据采集监控系统的硬件进行了选型。系统的总体设计方案包括硬件系统设计与软件系统的设计两大部分,采用研华远程I/O模块ADAM4017+即采集现场数据,通过ADAM4520模块与上位机建立通信,把现场数据上传至上位机,应用组态软件Kingview6.53实现系统的组态。把现场控制与数据采集的设计思路编制控制程序,实现系统的控制要求,即可以实现污水排放数据的全程监控。在监控中心由控制中心发布命令至控制单元S7-200PLC实现污水排放的远程控制。本文中污水排放指标的监测研究有助于水质自动监测工程的实施,并为环保等相关部门提供水质的实时监测、水质预报以及预防的技术支持。
[Abstract]:With the development of economy and the demand of science and technology, most of the domestic oilfield has entered the later period, the sewage yield gradually increased. Among them, a part of wastewater must be treated before discharge to surface waters, but because the process is not reasonable, exceed the standard content of the discharged sewage after May have some sources of pollution, emissions are not up to standard of national sewage, will be discharged into the environment, pollute the water, harm aquatic plants, may also have some fish and shellfish in the enrichment and eventually harm mankind. Therefore, emission monitoring of oil field sewage after treatment has become the focus of current research. In view of the current sewage discharge monitoring method is more complex and is not easy to control, is put forward the water quality monitoring system based on Kingview design index of sewage discharge to the Kingview software based on the data collection and monitoring system, the system mainly realize the data read, The data report query, history trend curve display, alarm, emission index standards to limit emissions and other functions, save a lot of manpower and resources. This paper first introduces the current situation and trend of water quality monitoring of sewage generated by the oilfield development at home and abroad, analyzes the advantages and disadvantages of traditional water quality monitoring method and the insufficiency, gives a design ideas the oil effluent monitoring system. Then according to the system monitoring and control requirements, from the composition of the system, the function of data acquisition and monitoring system hardware are selected. The overall design of the system including the design of hardware design and software system of the two parts, using Advantech remote I/O module ADAM4017+ to collect data, the establishment of communication through the ADAM4520 module and the host computer, upload data to the host computer, the application of configuration software Kingview6.53 to implement the system configuration. The idea of control program design of field control and data acquisition system, realize the requirements of control, which can realize the monitoring of sewage discharge data. Remote control in the monitoring center by the control center issued a command to the control unit S7-200PLC to achieve sewage discharge. Research on the sewage discharge monitoring indicators contribute to the implementation of automatic water quality monitoring project the real-time monitoring and provide water for environmental protection and other relevant departments, water quality prediction and prevention of technical support.
