The invention discloses obstruction type multi-module water quality biological detection equipment and an obstruction type multi-module water quality biological detection method. The equipment comprises an obstruction index selection module and a water quality testing device, wherein the obstruction index selection device is used for selecting a qualified or effective gradient obstruction degree combination, and the water quality testing module is used for detecting the water quality of the water body to be detected according to the behaviors of indicator organisms passing through each obstruction in the effective obstruction degree combination after being injected into the water body to be detected. According to the method, on the basis of behavior difference of the indicator organisms ina clean water body and a polluted water body, the distribution area of the indicator organisms is counted by establishing the relationship between the water body pollution degree and the distributionarea of the indicator organisms so as to determine the pollution degree of the water body. The method can accurately and quickly detect the pollution degree of the water body, does not need chemicalanalysis, physical detection and other technologies, and has the advantages of low cost, quick operation, accurate result and the like.
