Discharging and purification device for ship domestic sewage during navigation

Abstract

The invention discloses a discharging and purification device for ship domestic sewage during navigation. The device mainly comprises a separation chamber, a crushing chamber, a settling chamber and asewage collection box, wherein the separation chamber and the settling chamber are communicated with each other through a water diversion disc. The separation chamber comprises a gas outlet pipe anda separation mechanism. The separation mechanism comprises a conveying wheel and a filter belt. The crushing chamber is connected with the sewage collection box through a communicating pipe. The sewage collection box comprises a press-drying mechanism and a gas deodorizer, wherein the press-drying mechanism comprises a heating water removal plate and a plurality of telescopic rods. The settling chamber comprises a purified water outlet pipe and an adsorption layer. A plurality of pipelines are arranged in the water diversion disc, and an oil absorption rod is arranged in each pipeline. The crushing chamber comprises a crushing rod, a plurality of crushing cutters are horizontally arranged on the crushing rod, and when the crushing rod is static, the crushing cutters can be hidden in the crushing rod. The provided device is better in sewage treatment effect, is simple in operation, and is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of ship domestic sewage treatment, in particular to a device for discharging and purifying ship domestic sewage during navigation. Background technique [0002] Ship domestic sewage is the waste water discharged by passengers and crew members in daily life, such as kitchen sewage, washing sewage, etc., and domestic sewage discharge from ships also has relevant discharge standards in China. The most important. [0003] At present, most of the sewage on ships is initially filtered through a large filter screen. After being stirred and adsorbed by adding an adsorbent, it is finally precipitated. The sewage filtered in the first step cannot be treated in time. During the adsorption, it is necessary Stirring increases energy consumption, and the treated dirt is piled up for disposal, which is likely to cause air pollution and odor. Contents of the invention [0004] In order to solve the above technical probl...
