At that time, the treatment methods of broken branches were as follows: 01 stacking, which was transported by transport vehicles to the storage yard for temporary stacking; 02 crushing, part of the branches and leaves were crushed into flakes or powders by the branch crushing machine; 03 processing, part of the branches were sent to other places for processing, which could be made into fertilizer or furniture.
 After the branches were crushed
Does anyone remember the moranti incident in 2016? After the "moranti" rampage, hundreds of thousands of trees fell down in Xiamen, blocking all roads in the city. After a short period of three or four days of rescue and relief, the streets and alleys are unblocked again. Where are the trucks of branches and trunks sent to? How to deal with it? +By visiting Xiamen's yard, which has accumulated the most green garbage, the follow-up treatment process of these branches and trunks is revealed for you.

[data] 12 hectares of storage yard has been almost filled up
The rescue and relief work after typhoon is not only the end of road cleaning, but also the subsequent green garbage treatment. Due to the large amount of branches and trunks left by the rescue and relief work, Xiamen Municipal Bureau of landscape architecture has set up several temporary storage yards. Among them, the Yunding storage yard, which is located at the exit of Huandao Road of Yunding tunnel, is the "rear area" of the typhoon rescue and relief. It is open 24 hours a day to let all kinds of vehicles loaded with branches and trunks enter the storage yard for dumping.
At the scene of Yunding storage yard, the reporter saw that the whole storage yard was almost full, and those that could not be piled up were piled high with excavators. The highest green garbage had been piled up to nearly 6 meters high. On the road without asphalt pavement, a piece of yellow dust is raised by cars passing by. The front of each vehicle is hung with a sign of "rescue and disaster relief", and the vehicles are full of branches and trunks.
The reporter learned from Xiamen municipal engineering company, which is in charge of Yunding storage yard, that Yunding storage yard covers an area of about 12 hectares, equivalent to the size of 17 standard football fields. "On average, there are 2000 vehicles loaded every day, with the maximum on September 18, with nearly 5000 vehicles. The entire yard has been almost full, and now it is piled up with excavators." According to the person in charge, a 24-hour shift system has been implemented in the disaster relief work for a week. 190 loaders and 250 excavators have been put into operation. In the future, we will guide people to divert green garbage to other storage yards.
[Fire Prevention] continuous sprinkling of water to cool down the temperature, and a 5-meter-wide fire-proof isolation belt has been dug
The person in charge of Xiamen municipal engineering company, which manages Yunding storage yard, said that stacking high can relieve the space pressure, but the biggest problem is the potential fire hazard in the yard. The accumulated branches and leaves have been dried up, and the weather is fine and dry recently, which is easy to ignite.
Yunding storage yard is close to the mountain forest and Huangcuo. In case of fire, the consequences are unimaginable. "It's been the sun in recent days, so fire prevention has become the main focus of work." The person in charge said that a number of measures have been taken to deal with fire hazards.
In addition to setting up a number of eye-catching signs and slogans to remind the personnel entering and leaving the yard not to smoke and pay attention to fire prevention, the most important thing is that fire extinguishers and fire bombs are placed in many places in the yard, and the fire department and environmental sanitation department are invited to spray water to cool the temperature 24 hours a day, and fire isolation belts are also set up. Now, they have used excavators to dig a 5-meter-wide path around the yard to prevent the fire from damaging the mountains, forests and houses.
At the same time, in order to ensure safety, they also require all operators to wear safety equipment such as safety helmets and reflective clothing, and organize them to carry out fire fighting and escape drills.
However, with the passage of time, there will be more and more branches and leaves dried in the sun, which will become more and more dangerous. The best way to solve this problem is to let the storage yard have access to some places and dispose of the green garbage as soon as possible.
 Branch crusher
[purpose] social forces are widely involved in the transformation of waste into fertilizer and furniture
The green wastes such as branches and trunks transported here are not landfilled on site, but are of great use. They may be Make fertilizer Fuel furniture It can also be used to grow mushroom.
Jinshang road has a crushing plant, is a utilization Branch crusher A place where broken branches and leaves are crushed. Li Huamin, the person in charge of greening management center of Xiamen Municipal Bureau of landscape architecture, told reporters that after the typhoon, the crushing plant had been filled early.
All the selected branches and leaves are sent to the crushing plant. In the working area of the storage yard, a master is using a excavator to transport the branches and leaves to the track of the crusher. There are six workers near the track of the machine, wearing masks and gloves to help shape the residual branches and leaves on the track, so that the branches and leaves can be crushed smoothly. See branches and leaves into the machine, after a loud sound, the branches and leaves into the machine will become flake or powder. cover Branch crusher The crushed branches and leaves have been piled up into hills beside the pulverizer.
"There are bigger factories off the island. We will transport these crushed branches and leaves to retting. After half a year, they will be turned into organic fertilizer and finally returned to urban greening." Li Huamin said.
Among the numerous social forces, environmental innovation technology, which focuses on solid waste treatment equipment in Xiamen, also quickly mobilized waste crushers after the disaster and provided them to Xiamen municipal garden department for free. these ones here Branch crusher Work day and night silently, quickly break the branches and trunks into small pieces, and then compost them into organic fertilizer. There are two main uses: one is to make biomass fuel, which is what we call wood coal; the other is to make these branches and leaves into green fertilizer.
Because of the large amount of green garbage to be treated and the imminent fire hazard, it is far from enough to rely on the daily treatment work of the garden department. In this regard, the garden department also hopes to deal with these follow-up garbage through social forces, which has received a positive response.
Zhao Bin, a staff member of Xiamen Municipal Bureau of landscape architecture, told reporters that with the intervention of social forces, helping to digest the green garbage in the storage yard and alleviate the potential fire hazards, some enterprises also process and reuse the branches and trunks to get what they need. "Some enterprises can use the branches and trunks to grow mushrooms, while others can make fuel or fertilizer."
"What we deal with is mainly divided into two steps. First, the trunks with a diameter of more than 3 cm are picked out, and then transported to various places for further processing. Finally, they may be made into particleboards, wood-based panels, furniture, etc.; the rest will be crushed on site, and the crushed things may be re processed Processing into organic fertilizer It can also be used as green fuel for thermal power generation, or further processed into smaller and higher combustion value Bio pellet fuel 。” A person in charge of an enterprise said.
