一、问题的提出水是人类赖以生存的主要物质,在环境污染中,有相当一部分来源于水体的污染,人类用水是多方面的,属于环境保护学科研究的是排入水体中的或原存的有害物质引起的毒害,即有害物质原存于或排入水体中,直接、间接使人体中毒或使动、植物中毒。人类饮用水要求一定标准,而农田灌溉和渔业生产也都要求一定的水质标准。我国一九七九年十二月一日已颁布并执行《农田灌溉水质标准》和《渔业水质标准》。因此关于水质的分析,已成为环保工作十分重要的一环。水质分析,通常采用手工的方法对各项数据进行整理计算,这样做十分繁杂且费时易错,为寻求一条高效、准确的途径,本人根据多年从事水质分析工作的体会,总结出了在水质分析中采用计算机代替部分手工工作的方法,根据水质常规测定后的主要离
First, the issue raised Water is the main human survival of the material, in environmental pollution, a considerable part of the pollution from water, human water is multifaceted, belonging to the environmental protection discipline is discharged into the water or the original Poisoning caused by harmful substances stored, that is, the harmful substances originally exist in or discharged into the water body, directly or indirectly cause the human body poisoning or make the move, plant poisoning. Human drinking water requires a certain standard, while farmland irrigation and fishery production also require certain water quality standards. As of December 1, 1979, China has promulgated and implemented the Standards for Farmland Irrigation Water Quality and Fishery Water Quality Standards. Therefore, the analysis of water quality has become a very important part of environmental protection work. In order to find an efficient and accurate way for water quality analysis, we usually use manual methods to calculate and calculate various data. In this way, it is very complicated and time-consuming and error-prone. In order to seek an efficient and accurate way, based on our experience in water quality analysis for many years, In the computer instead of part of the manual work, according to the water quality after the main determination of the main
