Embodiment 1
[0035] The test was carried out in a small urban polluted river channel about 600 meters long and 8 meters wide. The water flow of the river is slow, and the water from the urban rainwater pipe and a small amount of domestic sewage are its main water sources. The water depth is about 0.2 meters, and the bottom mud thickness is about 0.2-0.3 meters. The lower half of the channel is affected by the tide of the Pearl River twice a day. During the whole test period, the temperature was 21-32°C, and the pollution holding conditions were basically the same. At the beginning of the test, 20 kg of ferric oxide and sodium humate composite preparation (proportioning 60% of ferric oxide and 40% of sodium humate) were added, and after being adjusted into a suspension with 200 kg of water, the whole river Sprinkle evenly in the section, and then add 20 kg of ferric oxide and sodium humate compound preparation every 30 days (use 200 kg of water to make a suspension and sprinkle evenly in ...
Embodiment 2
[0043] The experiment was carried out in an urban polluted river channel with a length of about 1000 meters and a width of 10 meters. The water flow of the river is slow, and the water from the urban rainwater pipe and a small amount of domestic sewage are its water sources. The water depth is about 0.3 meters, and the bottom mud thickness is about 0.2-0.4 meters. The whole river course is affected by the tide of the Pearl River twice a day. During the entire 60-day test period, the temperature was 21-30°C, and the pollution receiving conditions were basically the same. At the beginning of the test, 30 kg of ferric oxide and sodium humate composite preparation (proportioning 70% of ferric oxide and 30% of sodium humate) were added, and evenly poured into a suspension with 300 kg of water. Sprinkle, and add 30 kg of ferric oxide and sodium humate compound preparation every 30 days (use 300 kg of water to make a suspension and sprinkle evenly across the river). At the beginni...
