Ship oily sewage treatment device and method

Abstract

The invention discloses a ship oily sewage treatment device and method, and relates to the field of sewage treatment. According to the ship oily sewage treatment device and method, the device includesintegrated processing equipment, wherein the integrated treatment equipment internally comprises a flow regulation tank, a sludge storage tank, a deoxidation tank, a nitrification tank, a disinfection tank and a water outlet pump tank; isolation plates are arranged between the flow regulation tank and the sludge storage tank, between the sludge storage tank and the deoxidation tank, between the deoxidation tank and the nitrification tank, between the nitrification tank and the disinfection tank, and between the disinfection tank and the water outlet pump tank. Through isolation of the flow regulation tank, the sludge storage tank, the deoxidation tank, the nitrification tank, the disinfection tank and the water outlet pump tank, according to the ship oily sewage treatment device and method, ship domestic sewage enters the integrated treatment equipment through a matched collecting device, impurities and large-particle solids in the sewage are separated out through an aeration grid arranged at the front section, and large garbage impurities are removed, so that the effects of preventing the sewage from entering a subsequent sewage treatment process pool and blocking fillers and pipelines are achieved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a ship oily sewage treatment device and method. Background technique [0002] As the biggest source of pollution, domestic sewage is receiving increasing attention from management departments. National and local departments are stepping up efforts to manage this type of sewage and implement strict control standards in a targeted manner. Sewage contains a certain amount of pollutants such as organic matter, nitrogen, phosphorus, and oil; if such sewage is not treated and directly discharged into natural water bodies, it will consume a large amount of dissolved oxygen in the waste water, reduce the transparency of the bottom water body, and cause the receiving water body to The water quality is black and smelly, and even produces eutrophication of the water body; at the same time, a large amount of suspended solids will block the pipeline, etc.; it will seriously damage the ecologic...
