The invention relates to the technical field of water pollutant sampling, and discloses a wharf water pollution and fouling organism integrated sampler which comprises a mounting base plate mounted at the top of a wharf foundation pile through a bolt, and an integrated sampling assembly for integrally sampling water and fouling organisms is arranged below the mounting base plate. The integrated sampling assembly comprises a fouling organism collecting mechanism used for scraping and collecting fouling organisms, through an integrated structure, the fouling organism collecting mechanism (a fouling organism shoveling shell and a collecting bag) and a seawater collecting mechanism (a water storage bottle and a baffle) are integrated at the same execution tail end, and in single-time diving and scraping actions, the fouling organism collecting mechanism and the seawater collecting mechanism are separated from each other, so that the fouling organism collecting mechanism and the seawater collecting mechanism are separated from each other. The device is simple in structure and convenient to use, can complete shoveling and collecting of fouling organisms on a wharf pile foundation, can synchronously utilize water pressure to collect seawater pollution samples at the depth, avoids the tedious process that in a traditional sampling mode, different devices need to be put separately and operation is carried out twice, and remarkably improves the working efficiency of on-site sampling.
