中文摘要:
      针对目前我国工业点源水污染在线自动监测系统存在的废水取样和分析(测量)间隔时间过长导致废水污染物排放总量监测、计算不准确以及排污企业容易掌握其废水采样规律并经常偷排、突排高浓度废水而不能被有效监测的问题,提出一种按废水排放流量比例随机采样、统一存储综合水样进行污染物排放总量监测和计算的技术方案以及相应的智能化污水污染物总量监测系统结构,并阐述其工作原理。该智能化监测系统可有效克服现有水污染在线自动监测系统在运行中存在的计算时间长、监测误差大和取样规律易泄漏的缺陷。
英文摘要:
      There are some problems with the on-line automatic wastewater contamination emission monitoring system for domestic industrial pollution point source currently.For instance,the interval time of wastewater sampling and the process of measurement and analysis is too long,so that the monitoring and calculation for total amount of wastewater contamination emission are imprecise,and pollution emission enterprises are easy to grasp the law of waste water sampling and always discharge high concentration wastewater suddenly or by stealth.Considering the above mentioned problems,a technical solution to the on-line automatic monitoring system is proposed.The solution adopted random time interval for wastewater sampling which is in direct proportion to flow rate and stored every wastewater sample together for monitoring and calculating the total amount of wastewater emission.The architecture and work principle of the intelligent monitoring system are also introduced,which can effectively overcome many defects of the existing on-line automatic water pollution monitoring system,such as long computing time,large monitoring error and easy leakage of sampling rule.
