1 Scope

GB/T 10833-2023 is the Chinese national standard on technical condition for marine sewage treatment system, in the field of shipbuilding and marine structures. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 6 August 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 March 2024. Classification: ICS 47.020.90, CCS U25. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the requirements, test methods, inspection rules and marking, protection, packaging and storage of marine sewage treatment systems. This document is applicable to the design, manufacturing, testing and acceptance of domestic sewage treatment systems for various types of ships and fixed or mobile working platforms on the water.

3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Domestic sewage sewage There are four types of emissions from ships.

a) Discharge and other waste from toilets and urinals of any type;

b) Discharge from washbasins, bathtubs and drainage holes in medical offices (pharmacies, wards);

c) Discharges from spaces containing live animals;

d) Other wastewater mixed with the above effluents.

Note. The domestic sewage collected by the vacuum collection system is called vacuum black water, and the domestic sewage collected by the conventional gravity collection system is called gravity black water.

3.2 graywatergreywater Dishwashing water, kitchen sink water, shower water, laundry water, bathing water and face washing water discharged from the ship do not include cargo hold drainage and garbage.

Note. Depending on the degree of contamination, it is divided into kitchen gray water and washing gray water.
