Since October 26, there have been more cabbages floating from the upper reaches of the Han River. The Wuhan Liangjiang Waters City Appearance and Environmental Sanitation Center dispatched 7 drifting boats and 6 wooden boats to fight on two fronts to encircle and suppress the cabbage in the Wuhan section of the Yangtze River and han river to ensure that the clear water of the river flows eastward.
On the morning of the 4th of november, jimu news reporters directly attacked the "battle" of the two rivers and drifting on the spot.
The "big stomach king" can eat more than 100 tons in one breath
At about 10:00 a.m. on the 4th, a new type of drifting boat with a length of 40 meters that looked like a yacht drove from Jijiazui on the Han River to the Yangtze River to encircle and suppress water cabbage, and at its side, there was a transport ship accompanied by it, which could eat 150 tons of water cabbage, and the reporter witnessed its combat effectiveness with the ship.
After more than 20 minutes, the Qing drift boat crossed the Dragon King Temple into the Yangtze River. At this time, on the north bank of the Yangtze River, there are water cabbages floating one after another. The staff of the Wuhan Liangjiang Waters City Appearance and Environmental Sanitation Center told reporters that these water cabbages, since October 26, have been drifting from the upper reaches of the Han River, showing a growing trend. To ensure water quality and hygiene, timely bleaching is required.
When the new clear drift ship was about 50 meters offshore, it went up against the current and began to launch the battle. The captain opened the bow door of the silo and slowly advanced at a speed of 2 nautical miles on time. After the water cabbage floating on the river surface enters the silo at the bow of the ship, the toothed transmission belt continuously transports the water cabbage to the cabin, and then through the conveyor belt, it is sent to the garbage transport ship tied to the drifting ship.
The drift boat is too slow, can it be faster? The captain said that this rush could not come, and under the condition of ensuring safety, it was not possible to chase the water cabbage, nor should it be fast forward.
The reporter calculated the time, this drifting boat, 4 hours to "eat" into more than 100 tons of water cabbage, is more than 2 times the general drifting boat, is a full-fledged "big stomach king".
The two rivers in Wuhan have been comprehensively accelerated and water quality
Wuhan Liangjiang Waters City Appearance and Environmental Sanitation Center is responsible for the task of clearing and drifting a total of 40 kilometers of the Yangtze River and Jianghan River. The Yangtze River section runs from the Cockatoo Island Bridge to the Erqi Yangtze River Bridge, and the Han River section runs from the Jianghan Second Bridge to the Dragon King Temple.
On the morning of the 4th, Jimu News saw that the No. 1, 2, and No. 3 drifting boats surrounded and suppressed the cabbage in the Jianghan section, and the No. 5, 6, and 7 drifting boats entered the Yangtze River to fight. The 5 wooden boats are in the place where the mechanical drift boat cannot work, and the needle is inserted for the cleaning.
"More than 5 years ago, when the water hyacinth water cabbage broke out, it was all manually rowed in wooden boats, less than 100 tons a day." Chen Bin, deputy director of the Wuhan Liangjiang Waters City Appearance and Environmental Sanitation Center, said that the Wuhan Municipal Government has increased the protection of the Yangtze River water environment, and has purchased 6 mechanical drifting boats, with a cleaning capacity of more than 400 tons per day.
It is worth mentioning that the two new types of drifting boats purchased in the second half of 2019 adopt the operation mode of joint drifting with garbage removal ships, which greatly improves the efficiency of clearing and drifting, "the workload of one ship is equivalent to the amount of cleaning and drifting in the past 2 days." ”
The Jimu News reporter saw that from the drifting to the loading of the garbage transport ship, all "automated", after filling, the garbage transport ship will transport the water cabbage to the special wharf, and then transported away by the garbage compression truck for disposal. Chen Bin said that this kind of drifting mode is the most advanced in China and can make "a river of clear water flow eastward."
