The sewage after solid filtration is discharged into the oil filter through the dividing plate, and the sewage is filtered through the second drainage hole on the screen barrel. The filtered sewage falls into the purification device on the installation frame to filter the sewage. The sewage passes through the activated carbon layer, the filter cotton layer, the cation exchange layer and the disinfection layer to remove the odor, colloidal organic matter and some metal ions in the sewage, and then disinfected for recycling.

[0014] The present invention provides a domestic sewage discharge purification device for a seagoing vessel, which has the following beneficial effects:

[0015] 1. The present invention discharges the sewage after solid filtration into the oil filter through the dividing plate, ensuring that all sewage contacts the oil filter at the first time when entering the water storage tank, and filters the sewage through the second drainage hole on the screen barrel, reducing the cost of the stirring step, and adsorbing oil in the oil filter, so that the oil on the surface of the sewage in the water storage tank is reduced to a minimum, which is convenient for later recycling.

[0016] 2. The present invention uses a heating plate and a push rod motor. The output end of the push rod motor drives the heating plate to continue to extrude and heat the material and solid, so that the moisture in the material and solid is completely evaporated, and the water vapor is filtered through the exhaust port and the gas filter. The dried material and solid enter the collection box. When the collection box is full, the push plate is pushed from the rear end of the collection box to push the dried material and solid out of the box door. The two heating plates and the collection box can increase the drying speed without affecting the subsequent drying use. BRIEF DESCRIPTION OF THE DRAWINGS
