Ship sewage processing system

Abstract

The invention belongs to the technical field of breeding ship device manufacturing, and relates to a ship sewage processing system. A domestic sewage processing device for processing and discharging domestic sewage is arranged in a cabin on the lower side of an upper deck, a reagent adding opening for adding sterilizing and disinfecting reagents is formed in the right side of the upper side of thedomestic sewage processing device. The domestic sewage processing device on the left side of the reagent adding opening is connected with a ventilating main pipe for exhausting through a pipeline. Asewage inlet is formed in the lower end of the right wall of the domestic sewage processing device and connected with an outlet end pipeline on the left side of a four-way valve. The upper end o the four-way valve is an inlet end. The left end of a domestic sewage cabinet is sequentially connected with a flange cast iron sluice valve, a domestic sewage smashing pump, a flange cast iron sluice valve, a steel through cabin pipe fitting and an exhaust connector through pipelines. The domestic sewage smashing pump is used for smashing solid waste in the domestic sewage cabinet. The ship sewage processing system is simple in body structure, ingenious in design concept, safe, convenient and sanitary to manufacture and use and friendly to the application environment.

Description

Technical field: [0001] The invention belongs to the technical field of equipment manufacturing of breeding ships, and relates to a sewage treatment system on board, which can efficiently treat the sewage generated on the breeding ships. technical background: [0002] Cold-water fish live in sea areas with higher latitudes. The sea water temperature in these sea areas is low, which can meet the survival needs of cold-water fish. Water is taken from deep seawater for cultivation. In order to facilitate low-temperature seawater cultivation, the fish farming boats involved in the prior art are generally aimed at common fish species, and the fish farming is carried out on the fish tank on the deck of the fish farming boat, and the equipment requirements are relatively low. , At the same time, there is no perfect sewage treatment equipment on board, and all of them are discharged directly into the sea, which is easy to cause pollution.

Problems solved by technology

[0002] Cold-water fish live in sea areas with higher latitudes. The sea water temperature in these sea areas is low, which can meet the survival needs of cold-water fish. Water is taken from deep seawater for cultivation. In order to facilitate low-temperature seawater cultivation, the fish farming boats involved in the prior art are generally aimed at common fish species, and the fish farming is carried out on the fish tank on the deck of the fish farming boat, and the equipment requirements are relatively low. At the same time, there is no complete sewage treatment equipment on board, and they are all discharged directly into the sea, which is easy to cause pollution

Because cold-water fish have extremely high requirements on the living environment, the fish tanks on the existing fish farming boats are difficult to meet the survival needs of cold-water fish. In order to provide seawater with a suitable temperature for cold-water fish, the fish tanks also need to meet the requirements of environmental protection and heat preservation. The method adopted in the prior art is to adjust the water temperature through a temperature control system, but this method is time-consuming and labor-intensive, the efficiency is low and a large amount of energy is required, but the breeding effect is not ideal. To provide a suitable water temperature for cold-water fish The environment must be similar to the wild environment. The cruising farming boat can stay at sea all the time and provide seawater with suitable water temperature, but it needs aquaculture personnel to live on the fishing boat at sea all the time. It can not pollute the surrounding seawater and effectively treat the domestic sewage generated by the living people on board, so design an on-board sewage treatment system that can provide a stable low-temperature water source and be able to move freely on the sea to choose a suitable sea area
