Ship domestic sewage discharge supervision device

Abstract

The invention relates to the technical field of sewage discharge supervision, and discloses a ship domestic sewage discharge supervision device which comprises a domestic sewage treatment device. A water inlet of the domestic sewage treatment device is fixedly connected with a main drainage pipe, and the outer side wall of the main drainage pipe is fixedly connected with a first sewage discharge pipe. A water outlet of the domestic sewage treatment device is fixedly connected with a second blow-off pipe, and a first flow sensor and a first drainage control valve are fixedly connected to the positions, above and below the joint of the first blow-off pipe, of the outer side wall of the main drainage pipe respectively; According to the domestic sewage treatment device disclosed by the invention, the first flow sensor is arranged, so that the total displacement of water passing through the main drainage pipe on the current day can be monitored, by comparing the total displacement with the sewage discharge amount monitored by the third flow sensor after treatment and the weight sum of impurities such as suspended matters weighed by the weighing device, the device can be used as a basis for judging the service condition of the domestic sewage treatment device and judging whether the basic performance of treated sewage is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage discharge supervision, in particular to a ship domestic sewage discharge supervision device. Background technique [0002] The ship's domestic sewage treatment device is a device for treating ship's domestic sewage and discharging it up to the standard. Sewage mainly generated by the life of personnel on board the ship, including: a) discharge from toilets and other wastes in any form; b) washbasins and bath tubs in medical rooms (pharmacies, wards, etc.), and discharge from drainage holes in these spaces; c) effluents from spaces containing live animals; d) other sewage mixed with the above effluents or wastes. According to relevant statistics, the domestic sewage produced by ships is about 60-70L / person per day, the domestic sewage produced by ships in coastal waters of my country is about 11.25 million tons per year, and the domestic sewage produced by ships in inland waters is about 2590 tons ...
