The invention discloses a collecting, purifying and recycling process for pollution runoff of liquid bulk cargo wharfs, and belongs to the field of environmental protection of ports and wharfs. The process comprises a crude oil pollution runoff collection and pretreatment unit, a liquefied natural gas pollution runoff collection and pretreatment unit, a liquid chemical pollution runoff collection and pretreatment unit, a coagulating sedimentation unit, a biological retention treatment unit and a recycling unit. Pollution runoff of a crude oil tank area, pollution runoff of a liquefied natural gas tank area and pollution runoff of a liquid chemical product tank area are collected and pretreated through the crude oil pollution runoff collection and pretreatment unit, the liquefied natural gas pollution runoff collection and pretreatment unit and the liquid chemical product pollution runoff collection and pretreatment unit respectively and then enter a coagulating sedimentation unit; after being coagulated, floc
