污水监测实验：针对不同用水行为的污水采集方法

For different water usage behaviors, this experiment monitored the sewage generated at different monitoring points for each water usage behavior. The sewage collection work was completed by an automatic sampler to collect instantaneous water samples during the corresponding advantageous time period for each water usage behavior. The tap water sample was collected by letting the tap water flow and using a sampling bucket to collect a sufficient amount.
