Sewage treatment device based on shipbuilding

Abstract

The invention discloses a sewage treatment device based on shipbuilding in the field of ship sewage treatment, which comprises a sewage tank, the side wall of the sewage tank is provided with a water inlet mechanism and a water drainage mechanism, the two side walls of the sewage tank are symmetrically and fixedly connected with sewage discharge tanks, and the bottom ends of the sewage discharge tanks are fixedly communicated with arc-shaped sewage discharge pipes. By arranging the transverse cleaning mechanism and the longitudinal cleaning mechanism, a U-shaped scraping plate moves back and forth in the sewage tank to clean sludge in the sewage tank, meanwhile, through a cleaning plate, when the U-shaped scraping plate moves back and forth, the cleaning plate can move up and down to clean uncleaned places of the U-shaped scraping plate, dead-corner-free cleaning in the sewage tank is achieved, and the cleaning efficiency is improved. The sewage tank is ensured to be clean and tidy, sludge is prevented from being attached to the sewage tank, the problem that electronic equipment in the sewage tank is corroded due to the fact that sludge in sewage is attached to the sewage tank is solved, and meanwhile the sewage purification effect is reduced due to the fact that the sewage sludge concentration in the sewage tank is increased.

Description

technical field [0001] The invention discloses a ship-based sewage treatment device in the field of ship sewage treatment. Background technique [0002] With the continuous development of science and technology and information, ocean shipping and ocean development are also extremely developed. The random discharge of domestic sewage from marine ships has made the pollution of the marine environment more and more serious. In order to protect limited marine resources, countries around the world are actively taking measures to reduce or prevent marine pollution from ships or offshore platforms. [0003] In the prior art, for the sewage on ships, due to the presence of a large amount of sludge and particles in the sewage, when the sewage is treated, a large number of stains are often attached to the inner wall of the sewage purification container, which leads to corrosion of the equipment and reduces the effect of sewage purification. question. [0004] Based on this, the pre...
