Shipborne domestic sewage treatment system

Abstract

The invention relates to the technical field of sewage treatment, particularly to a shipborne domestic sewage treatment system, which comprises a sewage treatment module, a manure sludge treatment module and a thermoelectric control module, wherein the sewage treatment module comprises a solid-liquid separator, an oil-water separator, a sewage adjustment box, a MBR biofilm reactor and a clear water collection box, and the thermoelectric control module comprises a methanol water storage tank, a methanol water-to-hydrogen reformer, a heat exchanger, a fuel cell, an air residual gas mixer and a control device. Compared with the shipborne domestic sewage treatment system in the prior art, the shipborne domestic sewage treatment system of the present invention has the following characteristicsthat the sewage and the manure on the ship are separated so as to improve the sewage treatment efficiency and integrate the power supply, the heat supply and the manure sewage treatment, and the system has advantages of small occupation area, energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a ship-borne domestic sewage treatment system. Background technique [0002] With the unprecedented development of the shipping industry and ocean development, the environmental pollution of the ocean is becoming more and more serious, and human beings are paying more and more attention to the protection of the ocean. The problem of ship domestic sewage pollution brought by the ocean has also aroused great concern of human beings. Ship domestic sewage contains a large number of bacteria, parasites and even viruses and high concentrations of eutrophication substances. These untreated domestic sewage is discharged into the water environment without treatment, which will infect aquatic organisms and humans, endangering organisms and human health In addition, after nutrients enter the water environment, when their content is too high, algae can grow and reproduce excessivel...

AI Technical Summary

Problems solved by technology

Existing marine sewage treatment systems mostly use biochemical, physical and chemical methods, or electrolytic methods. These treatment devices are equipped with large cabinets such as sedimentation cabinets and disinfection cabinets, which occupy a large space on the hull, are inconvenient to use, and cost high. On the one hand, the operation of marine sewage treatment equipment depends entirely on the power supply of the generator set on board. Most of the generator sets are gasoline and diesel generator sets, which not only consume high energy, but also cause pollution to the environment, which is not conducive to energy conservation and environmental protection.
