Abstract

The invention relates to a domestic sewage treatment device for a ship. An aeration chamber, a precipitation chamber and a membrane chamber are formed in the body of the device respectively; the membrane chamber is a flat cube and is positioned on one side of the body; the aeration chamber and the precipitation chamber form a box type cube which is positioned on the other side of the body; a clapboard of which a half is isolated is arranged in the aeration chamber; the bottom of the precipitation chamber is funnel-shaped, and the top of the precipitation chamber is trumpet-shaped; and a wateroutlet cavity on the upper part of the precipitation chamber is positioned at the central position of the box type cube. Due to the design of the clapboard in the aeration chamber, a plug flow movement locus is formed while sewage is aerated by using an aerator at the bottom of the aeration chamber, so that higher biochemical reaction efficiency is realized for sewage; and by improving the structure of the precipitation chamber, the chemical oxygen demand (COD), biochemical oxygen demand after 5 days (BOD5) and total suspension solid (TSS) value can be lowered effectively. By improving the water outlet cavity of the precipitation chamber, a liquid in the precipitation chamber can keep in stable state no matter which direction the device is inclined in, and the stability of the device is further enhanced.

Description

technical field [0001] The invention belongs to the technical field of domestic sewage treatment devices used on ships, and in particular relates to a domestic sewage treatment device for ships. Background technique [0002] The domestic sewage treatment device used on the ship is different from the land, and has its special environment: due to the limited installation space, it requires high treatment efficiency; Less, the frequency of using the bathroom is uneven, and it is required to be more resistant to impact loads; due to the management mode of the unmanned cabin of the ship, it is required to have stable automatic working ability, etc. [0003] At present, there is no membrane bioreactor (MBR) process technology used in similar foreign products, so there are certain problems in terms of shock load resistance and stable operation. Most of the domestic similar products adopt membrane bioreactor (MBR) process technology, but there are still some defects in the structur...
