Abstract

The invention provides a synchronous processing device and method of ship waste gas desulfuration and denitration waste liquid and ship sanitary sewage. The device comprises a suspending area and a filler area. The upper portion of the suspending area is provided with an overflow area communicated with the filler area. A liquid inlet is communicated with the suspending area. A liquid outlet is communicated with the filler area. A stirrer is arranged in the suspending area. Inclined baffles are fixed to the two sides of the inner wall of the suspending area respectively. The filler area is sequentially provided with a ceramic ring layer, an activated carbon layer and a polyethylene multi-surface hollow spherical layer from top to bottom. Mixed liquid of the waste gas washing waste liquid and ship sanitary sewage is pumped in and makes sufficient contact with heterotroph activated sludge with sulfate reducing bacteria as the main part in the suspending area through stirring of the stirrer, and then the mixed liquid enters the filler area from an overflow opening in the upper portion of the suspending area, sequentially passes through all filler layers, makes sufficient contact with abiological membrane and is then discharged out of a water outlet in the bottom of the filler area. By means of the method, no carbon source is added, and the synchronous processing of sulfate and nitrite in the ship waste gas desulfuration and denitration waste liquid and organic matter in the ship sanitary sewage is realized.

Description

technical field [0001] The invention relates to a device and method for treating ship exhaust gas desulfurization and denitrification waste liquid, in particular to a device and method for synchronously treating ship exhaust gas desulfurization, denitrification waste liquid and ship domestic sewage. Background technique [0002] Air pollution caused by ship exhaust gas is becoming more and more serious, which has attracted the attention of international organizations and countries. In order to deal with the pollution of ship exhaust gas, the International Maritime Organization (IMO) formulated the "MARPOL73 / 78 Anti-pollution Convention", which put SO X and NO X Listed as the primary pollutants to be controlled, SO X and NO X emission control area. Since 2014, my country's Ministry of Environmental Protection has also launched a phased limit for ship engine exhaust pollutants, and set up ship emission control areas in key waters around the Bohai Sea, the Yangtze River Del...
