Description

Automatic operation control method of ship sewage storage device

Technical Field

The invention relates to the field of sewage treatment equipment, in particular to an automatic operation control method of a ship sewage storage device.

Background

During operation, a large amount of domestic sewage and waste materials are generated by ships, and the sewage and waste materials comprise sewage and waste materials generated in personnel or article cleaning processes, sewage and waste materials generated in cooking processes, excrement generated in personnel excretion processes and the like. These contaminants typically flow into the domestic sewage storage tank through the sewer system on the vessel. Because the ship can not carry out harmless treatment on the living needs, the ship can discharge pollutants in a living sewage storage tank after being supplied to the shore; or a special sewage transfer ship is used for extracting and transferring the sewage in the ship in the sailing process.

The existing ship sewage storage tank is simple in structure, only serves as a temporary storage container for pollutants, and is sucked and discharged by a dung suction truck when the ship sewage storage tank is in shore or transported, so that pollutant pretreatment cannot be carried out. The domestic sewage often contains a large amount of organic matters, and the pollutants can be biologically fermented in the storage tank to generate a large amount of flammable and explosive gases, so that great potential safety hazards are brought to the storage process of the domestic sewage. Meanwhile, solid matters in the sewage may be adhered to the inner wall of the container during temporary storage, so that a pipeline is blocked, and the sewage is not discharged. Meanwhile, the existing sewage storage tank needs a person to watch on the sewage storage tank on a regular basis, the internal reserves are checked, and the person needs to watch on and operate the sewage storage tank in the sewage discharge process.

Besides the sewage storage facilities on the ship, onshore sewage transfer and collection devices and the like have disadvantages. For example, the collection and transfer of the existing onshore sewage are mainly completed by a dung suction truck which needs to be butted with a sewage storage tank on a ship through a pipeline when in use and then the pipeline is recovered after the completion of sewage discharge and storage. The release and recovery of the existing pipelines are mostly finished by manpower, which is time-consuming, labor-consuming, dirty and smelly, and may cause sewage leakage to pollute a ship body, a water body, a bank or a wharf.

In the ship sewage collecting and transferring process, the automation degree of various related devices is relatively low, manual operation butt joint is needed, and flow statistics, cost settlement and the like are performed manually. These all reduce the efficiency of the sewage collection and transportation work greatly, and the low efficiency is reflected in the high cost of the sewage collection and transportation.

The high cost of sewage recovery, transportation and treatment leads to illegal and untidy behaviors such as disorder discharge and the like in part of shipping enterprises. If the pollutants on the ship are discharged into the water body, serious water body pollution accidents can be caused. Therefore, governments in various parts of China require overall planning and acceleration of the construction of onshore fixed receiving facilities and overwater mobile receiving capacity; a ship pollutant receiving system which takes onshore fixed facility receiving as a main body and takes overwater flow receiving as supplement is gradually formed, the ship pollutant receiving capacity of regions such as port wharfs in jurisdictions is comprehensively improved, the effect of 'being fully received due to receiving' is achieved, and effective links of ship pollutant receiving, transferring and disposing links are well made. Although there are huge sewage collection and transportation demands, the operating efficiency, the security etc. of the system and the equipment that current boats and ships sewage were collected and were transported all have obvious not enough, and the degree of automation of relevant equipment reduces, and the use relies on operating personnel to carry out manual processing completely, and the performance of equipment can not satisfy the demand in market.

The ship oil contamination storage apparatus 100 in this embodiment is different from the ship sewage storage apparatus described in embodiment 3 in that: the ship oil stain storage device 100 is additionally provided with an oil tank which is communicated with an oil recovery tank on the deck through a pipeline, and the inlet of the cutting sewage pump 10 is respectively communicated with the first box body 2 and the oil tank through a third three-way valve. The cutting dredge pump 10 is used to pump sewage in the first tank or oil in the oil tank, respectively, onto the deck.

The oil stain transfer vehicle in the embodiment is the oil stain transfer vehicle in the embodiment 1; the sewage treatment tank 300 is used for performing innocent treatment on domestic sewage collected from a ship. And after the collected oil is subjected to oil stain separation, oil components are recycled, and sewage components are discharged into a sewage treatment tank for harmless treatment.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
