摘要：
A toxic substance-detecting device detects toxic substances in water by use of a microorganism sensor to ascertain the safety of affluents flowing into sewage-treating processes, environmental waters such as rivers, and waters flowing into water purification plants and a water quality-monitoring system employing a detecting device. The device includes a fixed micro-organism membrane and apparatus for circulating a buffer solution of micro-organism substrate and nutrient to one side of the membranne and solutions of water to be examined, standard and cleaning water to the other side.
