Sudden oil pollution pre-treatment system for large water intake port

Abstract

The invention provides a sudden oil pollution pre-treatment system for a large water intake port. The pre-treatment system comprises a main body framework, an anti-collision device, a sewage blockage net, an oil enclosure device and a repair walkway. The main body framework is connected with a flood control wall to form an enclosed fence structure, consists of a main body fence and a side wing fence and comprises an outer column and an inner column fixedly compacted in water, and the outer column and the inner column are fixedly connected with an underwater connecting beam and an overwater connecting beam; the anti-collision device is movably connected with the outer column to float on water; the sewage blockage net is arranged in a surrounding way along the extension direction of the main body framework and is fixedly arranged on the inner column; and the oil enclosure device is fixedly arranged on the inner column of the main body framework, and the repair walkway is arranged at the top end of the inner column. By adopting the layout of the sudden oil pollution pre-treatment system, the problems of large oil pre-treatment capacity of the large water intake port of a tidal river and difficulties in treatment as a result of changes in the tidal flow and tidal range can be solved.

Description

technical field [0001] The invention relates to an oil pollution treatment device, in particular to a sudden oil pollution pretreatment system applied to a large water intake. Background technique [0002] The deteriorating sudden pollution accidents are an important threat to the safety of water sources and urban water supply in most cities at home and abroad. The Huangpu River is one of the main water sources for urban water supply in Shanghai. The water intake scale of the upstream water source is 7.05 million m3 / d, accounting for 80% of the city's centralized raw water supply. Since the water source of the Huangpu River is located in an open, mobile, and multi-functional water area, the water source is affected by sudden water pollution accidents, and the water intake is at high risk. [0003] In recent years, sudden pollution accidents of the Huangpu River have occurred frequently, posing a serious threat to the water quality of the water source. Among them, ship acci...
