Abstract
The invention discloses a biological water-quality detection method using said obstructive multi-module biological water-quality detection device. This device includes an obstruction index-selecting device and a water-quality testing device, wherein the obstruction index-selecting device is used to select a qualified or valid stepped obstruction level combination, the water-quality testing device detects the water-quality of the water body to be tested depending on the behavior at each obstruction in the valid obstruction level combination after injecting indicator organisms into the water body to be tested. The relationship between the degree of water pollution and the distribution area of indicator organisms is established and the distribution area of indicator organisms is counted in this method based on the difference between the behaviors of indicator organisms in the clean water body and the polluted water body count, so as to determine the degree of water pollution. The invention can accurately and quickly detect the degree of water body pollution, does not need the processes such as chemical analysis and physical detection, and has the advantages of low cost, fast operation and accurate results, etc.
