fig. 2 is a cross-sectional view of fig. 1.

The components in the figures are numbered as follows:

the sewage treatment system comprises a sewage tank 1, a sewage cofferdam 2, a gravity sewage collecting pipe 3, a metal hose 4, a connecting branch pipe 5, a gas-liquid separation valve 6, a stop valve 7, a sewage self-priming pump 8, a sewage valve 9, an emptying valve 10 and a valve operating platform 11.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments.

As shown in fig. 1 and fig. 2, the utility model discloses oil gas chemical industry pier ramp sewage collection device, bilge well 1 including holding sewage is equipped with a plurality of sewage cofferdam 2 on the ramp, still is equipped with two gravity sewage collecting pipes 3 along ramp downwardly extending on the ramp, and every sewage cofferdam 2 all is connected with a gravity sewage collecting pipe 3, and gravity sewage collecting pipe 3 passes through metal collapsible tube 4 and is connected with bilge well 1, is equipped with sewage self priming pump 8 on the metal collapsible tube 4, and is equipped with two sewage valves 9 that supply metal collapsible tube 4 to connect on the gravity sewage collecting pipe 3.

Wherein, a gas-liquid separation valve 6 is arranged on a connecting branch pipe 5 between the sewage cofferdam 2 and the gravity sewage collecting pipe 3, and a stop valve 7 is also arranged between the gas-liquid separation valve 6 and the gravity sewage collecting pipe 3 on the connecting branch pipe 5.

In addition, the lowest point of the sewage cofferdam 2 is provided with an emptying valve 10.
