From June to November 1985, we conducted a hygiene survey and evaluation of the water tanks in the high-rise buildings in Shenzhen. Hygiene survey: send questionnaires and field surveys to understand the time and level of building construction, reservoir capacity, structure, dust-proof equipment and cleaning frequency and time interval. Water Quality Inspection: After the adoption of the reservoir water and the reservoir without water, test items such as table. Test methods unified according to “drinking water test method”. Zn, Cu, Cd and Pb were measured by polarographic anodic stripping voltammetry.
