The invention provides a simulation method for controlling the biological disturbance effect of water earthworms by using benthic algae. The simulation method comprises a water environment preparation step, a benthic alga treatment step and a water earthworm treatment step, wherein the benthic alga treatment step comprises the following steps: fixing polyethylene meshes with the same area (154cm<2>) required for experiments on a fishing net, paving the fishing net on the surfaces of settlings in a eutrophic shallow water body on the bank of the Taihu lake, ensuring that the finishing net is pulled, taking out benthic algae to put into the experiments when the chlorophyll content of the benthic algae on experimental meshes reaches 4-6mu g/cm<2>, and paving the benthic algae on the settlings. According to the simulation method provided by the invention, the accurate simulation for controlling the biological disturbance effect of the water earthworms by using the benthic algae can be achieved ...

The invention provides an anti-clogging gutter inlet device of a novel three-dimensional mechanism. The anti-clogging gutter inlet device solves the technical problem that the existing gutter inlet is poor in discharging capacity and easy to clog, can effectively reduce clogging of the gutter inlet caused by impurities in runoff, and strengthens water passing capacity. The anti-clogging gutter inlet device comprises a rainwater perforaled strainer and a pipe section, wherein the lower end of the pipe section is connected with the front surface of the rainwater perforaled strainer, a plurality of discharging holes are formed in the peripheral wall of the pipe section, and a plurality of branch-shaped objects are arranged around the discharging holes. The anti-clogging gutter inlet device has the advantages of effectively preventing particulate matters and waste carried in the runoff from clogging the gutter inlet, improving discharging capacity, quickly discharging impounded surface water ...
