Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Such as Figure 1-6A kind of marine sewage treatment system shown, comprises circulating tank 1, first filter group 15, the second filter group 16, and circulating tank 1 communicates with the inlet of first filter group 15, the second filter group 16 respectively through circulating pump 8 Connection; both the first filter group 15 and the second filter group 16 are membrane filters. Membrane filters include silicon carbide membrane filters and alumina filters; the filter membrane of silicon carbide membrane filters adopts silicon carbide ceramic membranes, which have the characteristics of large flux and can be regenerated repeatedly; by filtering silicon carbide membranes, Reduce suspended solids, grease and COD in water samples to meet the requirements of subsequent treatment processes; it has the following advantages: hig...

Abstract

The invention discloses a marine sewage treatment system and method. The marine sewage treatment system comprises a circulating barrel, a first filter group and a second filter group. The circulatingbarrel is respectively connected with the inlets of the first filter group and the second filter group through a circulating pump. A cleaning agent barrel and a dilution barrel are respectively arranged at opposite corners of the circulating barrel. A dosing pump is arranged at the top end of the cleaning agent barrel. A dilution barrel drain valve and a flushing pump are sequentially arranged onan outlet pipeline at the lower part of the dilution barrel, and the dilution barrel is connected with cleaning inlets of the first filter group and the second filter group through the outlet pipelinerespectively. The method of the marine sewage treatment system comprises the following steps: normal operation; flushing alarm; flushing starting; water and medicine supplementing of the dilution barrel; and deslagging. The problems of large occupied area, high energy consumption and complex operation of the centrifuge used by the existing desulfurization tower are solved. The system has the advantages of small occupied area, flexible installation space, low power, high energy efficiency, simple operation, system automation and the like.

Description

technical field [0001] The invention relates to a treatment system, in particular to a marine sewage treatment system and method. Background technique [0002] The 71st session of the IMO Marine Environment Protection Committee was held in London in July 2017. The meeting once again clearly insisted that from January 1, 2020, ships sailing around the world must use low-sulfur oil with a sulfur content of less than 0.5% m / m, or use approved exhaust gas treatment systems or other technical methods To ensure that the total discharge of sulfide from ships does not exceed 2.0g / kWh. On October 25, the Maritime Safety Administration of the Ministry of Transport issued an announcement that starting from January 1, 2020, ships shall not discharge the wash water of the open exhaust gas cleaning system in my country's ship air pollutant emission control area. [0003] The pollution and harm caused by sulfur oxides in ship exhaust to the atmospheric environment and marine environment ...
