Marine food kitchen waste and sanitary sewage comprehensive treatment system

Abstract

The invention discloses a marine food kitchen waste and sanitary sewage comprehensive treatment system. The water outlet end of a mixed breaking grinding device is connected with the water inlet end of a multistage electrolytic flocculation device through a main pipeline, the water outlet end of the multistage electrolytic flocculation device is connected with the water inlet end of a multistage sedimentation device through a main pipeline, an exhaust pipe is arranged between the multistage electrolytic flocculation device and a gas collecting detecting exhausting device, the gas inlet end of the exhaust pipe is connected with the multistage electrolytic flocculation device, the gas outlet end of the exhaust pipe is connected with the gas collecting detecting exhausting device, a gas injecting device is connected with the multistage electrolytic flocculation device through a gas inlet pipe, and therefore mixed gas is injected into the multistage electrolytic flocculation device. A clean water flushing device is connected with the mixed breaking grinding device, the multistage electrolytic flocculation device and the multistage sedimentation device through a water conveying pipe. The marine food kitchen waste and sanitary sewage comprehensive treatment system is simple in structure, convenient to mount, low in manufacturing cost and capable of effectively improving the sewage water treatment capacity and effect.

Description

technical field [0001] The present invention and a treatment technology for ship domestic sewage, in particular, relate to a comprehensive treatment system for ship kitchen garbage and domestic sewage. Background technique [0002] With the unprecedented development of the shipping industry and marine development, the pollution of the marine environment is becoming more and more serious, and human beings are also paying more and more attention to the protection of the marine environment. Due to the pollution of domestic sewage from ships brought by shipping, it has gradually attracted people's attention. As a means of transportation in shipping, ships are a source of mobile pollution. The impact of the discharge of domestic sewage from ships on the ocean and inland rivers cannot be ignored with the increase in the number of ships. [0003] At present, domestic research is mainly on single sewage treatment, which is mostly limited to the ground (such as urban areas); there i...

Problems solved by technology

[0003] At present, the domestic research is mainly on a single sewage treatment, mostly limited to the ground (such as urban areas); there is no introduction to the process technology of the three kinds of sewage centralized and unified treatment such as ships, and the main technology of advanced foreign products The product uses seawater as an additive, and the electrolysis in it usually requires the introduction of additives for electrolysis. First, the existing additives are generally seawater, and seawater is a strong corrosive agent, which has extremely high requirements for the product itself, so the product itself is complicated and costly. High; and need to add auxiliary devices for seawater, and secondly, other types of products with additives can be used, but this will also limit the environment and the additives used, and cannot be applied and promoted on ships on a large scale
