Abstract

The invention provides a domestic sewage treatment system for ships, which includes a regulating tank and an anoxic pond, wherein the regulating pond is connected with the hull drainage system, the upper part of the regulating pond is provided with a preliminary filter, the bottom of the regulating pond is provided with a first pump body, and the second A pump body is connected with the mechanical grille, and the outlet of the mechanical grille is connected with the anoxic tank through a connecting pipe. There are several mixing gas pipes at the bottom of the anoxic tank, and an auxiliary material adding mechanism is installed at the top of the anoxic tank. An overflow tank is provided on the side, and is connected with the membrane bioreaction tank through the overflow tank. A membrane reaction mechanism is arranged in the membrane bioreaction tank, and a blower mechanism is arranged above the membrane reaction mechanism. This solution greatly reduces the usage load of fresh water resources on board and effectively saves resources.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a domestic sewage treatment system for ships. Background technique [0002] Ship domestic sewage mainly refers to human excrement water, including sewage and waste discharged from urinals, flush toilets, etc.; sewage and waste discharged from basins in wards, medical rooms, bath tubs and discharge holes in these places; and sewage and waste related to the above sewage and waste Mixed daily water (washing water, bath water, laundry water, kitchen washing water, etc.) and other water. For domestic sewage from ships, the main treatment methods are to directly install domestic sewage treatment devices on board and install domestic sewage collection devices. The first method is to discharge it directly into rivers after reaching the standard treatment, and the second method is to collect it on the shore for treatment. At present, the international marine sewage treatment devices mainly...
