论地表水流分质排放方法

Method of Surface Flow Discharging According to Water Quality

水质和水量分割在不同体系进行监测和管理的传统水污染治理技术,使水域只能被动接纳水体。为此,提出了一种创新技术体制——水流分质排放方法,建立了水质、水量监测和水体分流设施一体化的智能感知与控制系统。论述了实现该法的技术难点;运用相关性原理分析发现水质项目间存在多向相关项目,论证了从多向相关项目中选取能进行快速在线监测的项目以及求取和分级的方法;并按其监测速度分成若干优先监测级别,使被保护水域能快速选择性接纳符合水质管理目标的水体,实现创新技术体制。查新报告表明,在国内外未见相同文献。实践证明,该方法能快速灵敏选择水体,有效防止污染扩散和输移。

A new water pollution control system which intelligently integrates the water quality and water quantity monitoring and the discharge device is proposed to replace the traditional polluted water treatment in which the water quality and quantity monitoring and discharge device were segmented into different systems. It is effective to curb water pollution spread and transport. The technical difficulties of this new system is discussed in this paper. Statistical analysis based on relevance principle proves that there are some pollutants （named multi-related pollu- tant） whose quantities are respectively related to several pollutant quantities simultaneously. The pollutants which can be rapidly measured on-line are selected from the multi-related pollutants, and the measurement priority is di- vided into different levels according to the measuring speed. The method of seeking multi-related pollutants and classifying different priority levels are expounded in this paper. Factual engineering application shows that the new system not only enables the water area to actively choose water flow according to the water quality, but also sensi- tively refuses unqualified water flow and therefore the emergent pollution could be avoided effectively.
