A sewage treatment device [10]is disclosed for use with a toilet [12]having a water flush input [16]and a sewage output [22]. The invention incorporates a treatment tank [56]connected for receiving the sewage from the sewage output [22]of the toilet. A disinfectant holding tank [58]is included for holding a disinfectant such as conventional household bleach. A mascerator blade [74]is disposed within the treatment tank [56]for mascerating the sewage to reduce the size of the particulate matter within the treatment tank [56]. An electric motor rotates the mascerator blade [74]and simultaneously pumps a disinfectant from the disinfectant holding tank [58]to the treatment tank [56]. A discharge pump [86]discharges the treated sewage from the treatment tank [56]. A control senses the level of the sewage in the sewage treatment tank and controls the sequence of operation of the mascerator blade [74]and the discharge pump [86]. The sewage treatment device [10]is suitable for use with a marine head as well as toilets located in mobile vehicles and permanent installations.
