system of evaluation of chemical and bacteriological laboratory at purification plants of water supply and drain

摘要

A system of evaluation of the chemical and bacteriological laboratory at purification plants of water supply and drain includes control of metrological measurements of the indices of contaminants. Furthermore, besides internal and external control of measurements the laboratory carries out experimental check of chemical-and-physical and chemical indices, and then compares thereof with the coded indices of the state controlling inspection.
