A biohazardous liquid medical waste collection and treatment system provides on-site collection and treatment of surgical fluids. The system is mobile, and includes an upper unit and one or more lower units that are detachable from the upper unit. The upper unit includes a liquid disinfectant reservoir, liquid pump valves, and an electronic control unit which controls the operation of the pump valves. A disposable suction canister is mounted to the upper unit and collects liquid medical waste aspirated from a patient. A disposable tube set, including a motionless mixer, is connected to the disposable suction canister and the liquid disinfectant reservoir. Electronically controlled pumps (preferably peristaltic pumps) pump liquid waste from the suction canister along with the metered amount of liquid disinfectant from the liquid disinfectant reservoir through the motionless mixer and into a temporary storage receptacle on the lower unit. When full, the lower unit is detached from the upper unit and a battery powered discharge pump empties the lower unit. A timer relay is provided on the lower unit to postpone discharge pump operation until the expiration of a preselected disinfectant treatment time.

[ I claim:] [40.] A method of treating a biohazardous liquid medical waste on-site comprising the steps of:pumping biohazardous liquid waste from one or more suction chambers and contemporaneously flowing liquid disinfectant from a liquid disinfectant receptacle;mixing the liquid disinfectant from the liquid disinfectant receptacle with the pumped liquid waste to form a mixture of liquid waste and liquid disinfectant;flowing the mixture of liquid waste and liquid disinfectant into a treated waste temporary storage receptacle;monitoring flow of the mixture of the liquid waste and liquid disinfectant into the treated waste temporary storage receptacle;holding the mixture of liquid waste and liquid disinfectant in the treated waste temporary storage receptacle for a preselected disinfectant treatment time period after the instant in time that any amount of the mixture of liquid waste and liquid disinfectant has flowed into the treated waste temporary storage receptacle;pumping the mixture of liquid waste and liquid disinfectant from the treated waste temporary storage receptacle after holding the mixture of liquid waste and liquid disinfectant in the treated waste temporary storage receptacle until expiration of the preselected disinfectant treatment time period. [42.] A method as recited in claim 40 wherein the liquid disinfectant is flowed from the liquid disinfectant receptacle by pumping the liquid disinfectant from the liquid disinfectant receptacle. [43.] A method as recited in claim 42 wherein the liquid waste is pumped by a liquid waste pump and the liquid disinfectant is pumped by a liquid disinfectant pump and the method further comprises the steps of:monitoring whether the liquid disinfectant pump is pumping liquid disinfectant; anddisabling a liquid waste pump used to pump the liquid waste when the liquid disinfectant pump is not pumping liquid disinfectant.
