Embodiment 1
[0040] A new type of composite coagulant, including the following components by weight: 70 parts of diatomite, 20 parts of potassium aluminum sulfate, 20 parts of sodium carbonate, 15 parts of inorganic chelating agent, 15 parts of buffering agent, and 8 parts of enzyme bioaccelerator 6 parts, fishy and deodorizing agent 6 parts;
[0041] In this embodiment, the inorganic chelating agent is polyphosphate or sodium sulfosulfate; the fishy and deodorizing agent is citric acid.
[0042] The in-situ dredging and ecological restoration technology of rivers and lakes using the new composite coagulant is as follows: in narrow and shallow rivers, the mud at the bottom of the river channel is mixed with the new composite coagulant by mechanical and manual methods. Fully stir for 5 minutes at a ratio of 100:1; in deep and wide rivers and lakes, use a cutter suction dredger to suck the sludge from the bottom of the river or lake to the cabin, and use a ratio of 100:1 Add the new composite...
Embodiment 2
[0044] A new composite coagulant, including the following components by weight: 80 parts of diatomite, 25 parts of potassium aluminum sulfate, 25 parts of sodium carbonate, 18 parts of inorganic chelating agent, 16 parts of buffering agent, and 9 parts of enzyme bioaccelerator 7 parts, fishy and deodorizing agent 7 parts;
[0045] In this embodiment, the inorganic chelating agent is polyphosphate or sodium sulfosulfate; the fishy and deodorizing agent is citric acid.
[0046] The in-situ dredging and ecological restoration technology of rivers and lakes using the new composite coagulant is as follows: in narrow and shallow rivers, the mud at the bottom of the river channel is mixed with the new composite coagulant by mechanical and manual methods. Fully stir for 4 minutes at a ratio of 110:1; in deep and wide rivers and lakes, use a cutter suction dredger to suck the sludge from the bottom of the river or lake to the cabin, and use a ratio of 110:1 Add the new composite coagu...
Embodiment 3
[0048] A new composite coagulant, comprising the following components by weight: 70-90 parts of diatomaceous earth, 20-30 parts of aluminum potassium sulfate, 20-30 parts of sodium carbonate, inorganic 15-20 parts of chelating agent, 15-20 parts of buffering agent, 8-10 parts of enzyme bioaccelerator, 6-8 parts of fishy and deodorizing agent.
[0049] In this embodiment, the inorganic chelating agent is polyphosphate or sodium sulfosulfate; the fishy and deodorizing agent is citric acid.
[0050] The in-situ dredging and ecological restoration technology of rivers and lakes using the new composite coagulant is as follows: in narrow and shallow rivers, the mud at the bottom of the river channel is mixed with the new composite coagulant by mechanical and manual methods. Fully stir for 3 minutes at a ratio of 120:1; in deep and wide rivers and lakes, use a cutter suction dredger to suck the sludge from the bottom of the river or lake to the cabin, and use a ratio of 120:1 Add th...
