Principle and Structure of Marine Sewage Collection Tank

Domestic sewage collection tank is used for storing raw sewage or solid residue treated by sewage treatment device on various ships. It can also be used as a transfer cabinet with sewage treatment device. This device has the functions of dosing and disinfecting, crushing the residue, flushing in the cabinet and discharging the treated sewage residue to the outboard. This article will introduce the principle and structure of the domestic sewage storage tank for you.

Overview

Principle Overview

After the raw sewage or sewage treatment device is treated, the solid residue enters the fecal disinfection storage cabinet, accumulates to a certain liquid level in the cabinet, and starts the crushing pump. The sewage or solid residue is repeatedly recycled and crushed, and drugs are added at the same time for disinfection. When the sewage or solid residue is crushed to a certain extent, the sewage can be sent to the shore receiving facility through the deck international discharge joint or directly discharged to the outboard in the unregulated sea area. In the sea area with stricter discharge requirements, it can also be connected to the domestic sewage treatment device for further treatment.

Structure

Marine sewage collection tank is a kind of equipment used on ships, and its main functions are to collect, crush, disinfect and store domestic sewage. It usually consists of the following parts:

Storage tank body: A container used to store domestic sewage, usually made of corrosion-resistant materials.
Crushing pump: Crush the solid substances in the sewage into smaller particles for subsequent treatment and discharge.
Disinfection device: Disinfect the sewage to kill the bacteria and viruses therein.
Control box: Used to control the operation of the equipment, including the start and stop and running time of the crushing pump, disinfection device, etc.
Float level switch: Monitor the liquid level in the storage tank, and when the liquid level reaches a certain height, start the corresponding equipment for treatment or discharge.

Using a marine sewage storage tank can effectively treat domestic sewage on ships and reduce environmental pollution.
