这段有关工业水处理的英文，我不是太明白，请前辈们帮忙解释一下，谢谢


The industrial waste survey involves a procedure designed to develop a flow-and-material balance （物料平衡）of all processes using water and producing wastes and to establish the variation in waste characteristics from specific process operations as well as from the plant as a whole.The results of the survey should establish possibilities for water conservation and reuse and finally the variation in flow and strength to undergo wastewater treatment.




The sewer map should indicate possible sampling stations and a rough order of magnitude of the anticipated flow.
