Embodiment 1-3

[0121] use figure 1 The sewage treatment system of the finished oil depot shown in the figure sequentially processes the sewage of the finished oil depot in the regulating tank 1, the grease trap 2, the air flotation tank 3, the hydrolytic acidification tank 4, the biological oxidation tank 5, the sedimentation unit 6, the internal circulation BAF tank 7 and the ozone catalytic oxidation pool 8 for processing. Among them, the flexible filler suspended in the hydrolytic acidification tank 4 is polyamide fiber bundle; the biological oxidation tank 5 is equipped with an aeration device and activated sludge, and the pollutants in the biological oxidation tank 5 are adsorbed and degraded by aerobic microorganisms , and the sewage enters the pool through the aeration device and can be fully mixed with the activated sludge in the pool immediately; the sedimentation unit 6 is a sedimentation tank, and the bottom of the sedimentation tank is provided with a mud bucket for mud-water sep...

Abstract

The invention relates to the field of wastewater treatment, and discloses a product oil depot sewage treatment system and a product oil depot sewage treatment method. The product oil depot sewage treatment system is sequentially provided with a regulation tank (1), an oil separation tank (2), an air floatation tank (3), a hydrolysis acidification tank (4), a biological oxidation tank (5), a precipitation unit (6), an internal circulation BAF tank (7) and a catalytic ozonation tank (8) according to the flow direction of treated sewage. By means of the product oil depot sewage treatment system and the product oil depot sewage treatment method, organic pollutants in the product oil depot sewage can be thoroughly degraded, and up-to-standard sewage discharge is achieved.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a sewage treatment system for a finished oil depot and a treatment method for the sewage of the finished oil depot. Background technique [0002] The top water operation of the product oil depot will produce a large amount of oily sewage, the sewage discharge cycle is irregular, and the sewage water quality is characterized by high petroleum, high COD and poor biodegradability (B / C<0.2). At present, the oil separation-air flotation-biochemical treatment process is commonly used in oil depots. Because of the high concentration of pollutants in oil depot sewage and poor biodegradability, this process cannot completely degrade organic pollutants in sewage, and it is difficult to achieve sewage discharge standards. Contents of the invention [0003] The purpose of the present invention is to overcome the problem that the sewage of finished oil depots in the prior art is diffi...
