The invention discloses a port oil spill sewage treatment structure and a treatment method thereof. The port oil spill sewage treatment structure includes a degreaser, a neutralization device, a flocculation device, an air flotation device, a sand filter, and an ultrafiltration reverse osmosis membrane device arranged and connected sequentially in sequence. The degreaser includes a housing, a partition installed in the housing and dividing the housing into a filter area and an oil removal area along the X direction, and a filter device installed on the housing and located in the filter area for primary filtration An oil removal device installed on the shell and located in the oil removal area for oil-water separation. The neutralization device has the same structure as the flocculation device, and the neutralization device includes a tank body and a stirring device installed on the tank body for increasing the reaction speed. The invention overcomes the deficiencies of the prior art and provides a treatment structure specially used for port sewage, which solves the problems of long treatment time and poor treatment effect of the existing port oily sewage.
Description
technical field [0001] The invention relates to the technical field of port sewage treatment, in particular to a port oil spill sewage treatment structure and a treatment method thereof. Background technique [0002] As a hub for water and land connection, ship loading and unloading, and transit transportation, the comprehensive treatment and resource utilization of sewage is directly related to the environmental quality of the port and the level of resource-saving port construction. [0003] The port sewage has a high oil concentration, and the oily sewage in the port mainly comes from four aspects: ballast water, tank washing water, engine room water and oily sewage produced by accidental oil spills. Ballast water is the ballast water to be drained by the tanker before loading oil in the port. The oil concentration of the ballast water is generally 1000-2000mg / L; the tank washing water is the tanker that needs to be used before changing the type of oil loaded or entering t...
