Abstract
A waste liquid treatment apparatus, a method, and a sample analyzer are provided. The waste liquid treatment apparatus is used for treating waste liquids in waste liquid pipes, and includes at least two waste liquid chambers, a pressure supply device, and a control device. Each waste liquid chamber communicates with at least one waste liquid pipe, and is used for collecting the waste liquid in the waste liquid pipe connected thereto when the inside of the waste liquid treatment chamber is in a negative pressure state. The pressure supply device is connected to each waste liquid chamber, and the control device is configured for controlling the pressure supply device to supply air pressure to each waste liquid chamber, so that the inside of at least one waste liquid chamber is in a negative pressure state at any time during waste liquid treatment, thereby effectively shortening a waste liquid treatment cycle.
