Sewage treatment equipment for ships

Abstract

The invention discloses sewage treatment equipment for ships. The sewage treatment equipment comprises a precipitate filtering tank (3), an anaerobic fermentation tank (4), a secondary precipitation tank (6), a secondary filtering tank (7), a water collecting tank (9) and a cover plate (5), wherein the precipitate filtering tank (3) is provided with a water inlet pipe (1); the middle upper part of the precipitate filtering tank (3) is provided with a stainless steel filter screen (2); the water collecting tank is communicated with a water outlet pipe (10); the cover plate (5) is used for enclosing the anaerobic fermentation tank (4), and is provided with a sewage disposing port; the sewage disposing port is provided with a cover cap; at least two groups of filtering layers (8) are formed in the secondary filtering tank (7), so that biogas residues left after anaerobic fermentation are convenient to clear; a micropore ceramic filter assembly is arranged in each filtering layer; the lower parts of the precipitate filtering tank (3) and the secondary precipitation tank (6) are provided with sludge outlets; and an outlet for clearing filtered substances is formed beside the stainless steel filter screen (2) on the precipitate filtering tank (3).

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to marine sewage treatment equipment. Background technique [0002] For a long time, due to historical reasons, a large amount of sewage on transport ships has been directly discharged into rivers and lakes, seriously polluting natural water sources, and will directly affect the living environment of human beings if things go on like this. They all use land domestic sewage treatment equipment. Since the ship is often tilted and turbulent when navigating inland rivers, the space on board is small. In particular, some domestic sewage treatment equipment must use a power device, and the water flow is pumped by a water pump. The noise is loud and there is For secondary pollution, regular maintenance is also required. For the living environment on board, land-use domestic sewage treatment equipment has poor applicability, poor treatment effect, and inconvenient operation. [0003] In par...

[0002] For a long time, due to historical reasons, a large amount of sewage on transport ships has been directly discharged into rivers and lakes, seriously polluting natural water sources, and will directly affect the living environment of human beings if things go on like this. They all use land domestic sewage treatment equipment. Since the ship is often tilted and turbulent when navigating inland rivers, the space on board is small. In particular, some domestic sewage treatment equipment must use a power device, and the water flow is pumped by a water pump. The noise is loud and there is Secondary pollution, in addition, special personnel are needed for regular maintenance. For the living environment on board, land-use domestic sewage treatment equipment has poor applicability, poor treatment effect, and inconvenient operation.
