１水平衡测试的概念 水在一个地区，一个企业，一个车间乃至一台用水设备中总是保持平衡的未确定用水体系，输入体系的水量始终等于输出体系的水量，如下图１。 输入体系的水量为取水量（Ｑ）十重复利用水量（Ｃ），输出体系的用水量为排水量（Ｐ）十耗水量（Ｈ）十重复利用水 1 The concept of water balance test Water in an area, a business, a workshop and even a water equipment is always balanced water system is not the same, the water input system is always equal to the volume of water output system, as shown in Figure 1. The amount of water input to the system is the amount of water taken (Q) ten times the amount of water reuse (C), the output of the system for the displacement of water (P) ten water consumption (H) ten water reuse
