Embodiment 1

[0022] Example 1 Laboratory simulation experiment of sediment restoration

[0023] Two 2*1*1 plastic boxes are used as experimental simulation devices. The bottom mud at the bottom of each device is 15cm thick, and the bottom mud is taken from the campus river. Then add river water to a depth of 70cm. After 10 days of static cultivation, the nutrient exchange between the bottom mud and the overlying water was basically completed. The No. 1 device was used for restoration, and the No. 2 device was used as a control.

[0024] On the 11th day, in the No. 1 device, add 20,000 water silk worms, equal in size, each with a length of 2-3 cm. After 3 days, add 400 river clams, equal in size, each weighing 2-4g.

[0025] From the 15th day, the phosphorus concentration in the overlying water of the two devices was monitored. And every 10 days, the overlying water of the two devices is pumped out, and then the tap water that has been dried (dechlorinated) is added to accelerate the release ...

Abstract

The invention discloses a novel method for combined usage of Corbicula fluminea and Limnodrilus hoffmeisteri in inhibition of release of endogenous phosphorus in a closed water body. The method comprises the following steps: 1) adding Limnodrilus hoffmeisteri into sediment; 2) adding Corbicula fluminea in 2 to 3 days; and 3) detecting the concentration of phosphorus in water in each ten days until the concentration of phosphorus is stable. According to the invention, resources are saved, new chemical risks are prevented from being introduced into the water body, the purpose of control of release of endogenous phosphorus is realized, and the landscape function of the water body is prevented from being destroyed in the process of restoration of the water body.

Description

Technical field [0001] The invention relates to an environmental treatment technology, in particular to a new method for inhibiting the release of source phosphorus from enclosed water bodies by the combination of river clam and vermicompost. Background technique [0002] For closed water bodies that have already intercepted non-source pollution, endogenous release is the key to maintaining the nutrient content of the water body. It is precisely because of the release of endogenous sources that the water quality of the water body has not been significantly improved in the short term. Although people have adopted the restoration technology of intercepting the source, in the long run, if the endogenous release cannot be effectively controlled, it will be in the sediment in the long term. The continuous circulation among water, water and organisms will affect the repair effect. [0003] For eutrophic water bodies, people usually use chemical, physical and environmental dredging metho...
