Embodiment 1
[0045] A small watershed river restoration method, comprising the following steps:
[0046] S1. Salvage the solid waste deposited in the river, and remove the non-degradable debris in the bottom mud of the river;
[0047] S2, put into the river channel the adsorption microspheres with a particle size of 20cm, after stirring for 2 hours, let stand for 24 hours to remove the adsorption microspheres;
[0048] The adsorption microspheres are composed of citric acid, pullulan and zeolite with a mass ratio of 6:1:12; the added amount of the citric acid is 0.06% of the weight of the river bottom mud;
[0049] S3, throwing modified clay and composite strains in the river;
[0050]The modified clay is composed of calcium nitrate, clay and chitosan with a mass ratio of 1:100:2; the added amount of the modified clay is 0.05% by weight of river water body;
[0051] The composite bacterial species is composed of Bacillus subtilis, yeast, nitrifying bacteria and ammonia oxidizing bacteria...
Embodiment 2
[0054] A small watershed river restoration method, comprising the following steps:
[0055] S1. Salvage the solid waste deposited in the river, and remove the non-degradable debris in the bottom mud of the river;
[0056] S2, throwing into the river channel the adsorption microspheres with a particle size of 15 cm, after stirring for 3 hours, let stand for 36 hours to remove the adsorption microspheres;
[0057] The adsorption microspheres are composed of citric acid, pullulan and zeolite with a mass ratio of 6:1:12; the added amount of the citric acid is 0.02% of the weight of the river bottom mud;
[0058] S3, throwing modified clay and composite strains in the river;
[0059] The modified clay is composed of calcium nitrate, clay and chitosan with a mass ratio of 1:100:2; the added amount of the modified clay is 0.1% by weight of river water body;
[0060] The composite bacterial species is composed of Bacillus subtilis, yeast, nitrifying bacteria and ammonia oxidizing ba...
Embodiment 3
[0063] A small watershed river restoration method, comprising the following steps:
[0064] S1. Salvage the solid waste deposited in the river, and remove the non-degradable debris in the bottom mud of the river;
[0065] S2, throwing into the river channel the adsorption microspheres with a particle size of 18 cm, after stirring for 2.5 hours, let stand for 32 hours to remove the adsorption microspheres;
[0066] The adsorption microspheres are composed of citric acid, pullulan and zeolite with a mass ratio of 6:1:12; the added amount of the citric acid is 0.04% of the weight of the river bottom mud;
[0067] S3, throwing modified clay and composite strains in the river;
[0068] The modified clay is composed of calcium nitrate, clay and chitosan with a mass ratio of 1:100:2; the added amount of the modified clay is 0.08% by weight of the river water body;
[0069] The composite bacterial species is composed of Bacillus subtilis, yeast, nitrifying bacteria and ammonia oxidi...
