Problems solved by technology

Sewage from ships is not easy to store in sewage tanks for too long, and the cost of treatment on the hull itself is relatively high. For a long time, ships have secretly discharged to lakes and rivers, causing serious pollution

Embodiment 1

[0028] Add the anaerobic / anoxic / oxygen-consuming activated sludge that has been domesticated in the early stage to the anaerobic / anoxic / oxygen-consuming unit in the integrated equipment, and the microorganisms in the MBR membrane pool are added to the membrane reactor, and gradually Into 80-100m 3 Sewage, an average of 400m is added to the integrated equipment every day 3 The sewage was activated for microorganisms. After 8 days of intermittent operation, it was found that COD, ammonia nitrogen and total phosphorus could meet the direct discharge standards after 5 days of continuous operation. After that, it began to officially operate to treat ship domestic sewage. Collect 100-120 domestic sewage from ships every day. When the ship is docked in the service area, it is connected to the sewage tank on the ship through a 60-meter-long water pipe on the collection device. After different ships arrive at the port, the sewage is collected by the domestic sewage, and gradually reac...

Abstract

The invention discloses a shipping domestic sewage treatment system. The shipping domestic sewage treatment system mainly includes a PLC control system, a sewage collection unit, an oil separation andregulation unit, a biochemical treatment unit and a sewage detection and discharge unit, and the above-mentioned units are automatically controlled by the PLC control system. The sewage collection unit includes a pumping device separately connected to a shipping sewage tank effluent joint and a sewage conveyor pipe and a sewage collection tank connected to pipelines; the oil separation and regulation unit includes an oil separation tank connected to sewage collection tank effluents and a biochemical regulation tank connected to oil separation tank effluents; the biochemical treatment unit includes anaerobic/anoxic/aerobic systems and a MBR membrane biological reaction system connected to anaerobic/anoxic/aerobic system effluents, and the anaerobic/anoxic/aerobic systems are separately provided with an aeration device used for regular aeration to prevent local sludge accumulation and aeration during reaction; and the sewage detection and discharge unit includes on-line detection equipment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a ship domestic sewage treatment system and integrated equipment. Background technique [0002] As an important means of transportation for inland river and ocean shipping, ships play an important role in the turnover of cargo transportation. In recent years, with the increasing frequency of shipping activities, the lake environment has deteriorated sharply, and the eutrophication of river water and crude oil spills caused by ships The phenomenon has attracted the attention of the country, and people have paid more and more attention to reducing the discharge of sewage from ships and reducing the pollution of lakes. [0003] Ship domestic sewage is mainly the kitchen wastewater, washing sewage and toilet sewage generated in the lives of people on board. Sewage contains domestic impurities, suspended solids, etc. In addition to high COD and SS values, it also contains oi...
