Ship domestic sewage treatment system

Abstract

The invention discloses a ship domestic sewage treatment system. The system comprises a domestic sewage treatment device and a domestic sewage storage cabin, the domestic sewage treatment device is connected with a sewage inlet pipe, a sewage discharge pipe and a first ventilation pipe, and the sewage inlet pipe is connected with a living black water pipe system; the sewage discharge pipe is respectively connected with a shore-through discharge pipe, a sea discharge pipe and the domestic sewage storage cabin through the stop check valves, and a standard joint and a wave-proof valve are respectively arranged on the shore-through discharge pipe and the sea discharge pipe; the domestic sewage storage cabin is connected with a domestic sewage crushing pump, the outlet side of the domestic sewage crushing pump is respectively connected with the sewage inlet pipe, the shore-through discharge pipe and the sea discharge pipe through the stop check valves, and the domestic sewage storage cabinis connected with a second vent pipe. The system meets the laws and regulations at home and abroad, improves the functions of an original system, is convenient to transform, prolongs the storage timeof the ship domestic sewage, reduces the maneuvering sewage discharge time and frequency during ship anchoring and berthing, saves energy, reduces emission, reduces the cost of a ship owner, is greenand environment-friendly, and protects the water area environment.

Description

technical field [0001] The invention relates to the field of ship domestic sewage treatment, in particular to a ship domestic sewage treatment system. Background technique [0002] With the continuous improvement of environmental protection laws and regulations, the protection standards for water environment, especially inland water environment, are getting higher and higher. The discharge control of ships' daily sewage is becoming more and more stringent, and the volume of traditional marine sewage treatment devices is too small to meet the actual conditions of ship production. For example, if a ship docks or anchors for more than 3 days, the treatment device will not be able to hold the domestic sewage generated. It must be anchored and sailed to drain the domestic sewage, and then berthed or anchored, resulting in a lot of waste of manpower and energy. Contents of the invention [0003] The object of the present invention is to provide a ship domestic sewage treatment ...
