Chapter 1,558 A completely different city of the future
【Corrected version】
What surprised these reporters was far more than that. On the streets, you will see a green vehicle with flashing work warning lights. These are sanitation work vehicles. They come in different sizes. Large ones such as sprinklers, garbage trucks, etc.
Cleaning trucks, fog cannon trucks, street washing trucks, etc., while medium-sized sanitation vehicles include street sweepers, street vacuum trucks, etc. As for small vehicles, they are more diverse and abundant, such as on the sidewalks on both sides of the road.
Ground sweepers, mobile garbage trucks, high temperature and high pressure sewage cleaning trucks, etc.
Of course, such a rich family of sanitation vehicles is not the focus of these media reporters. What they are concerned about is that the vast majority of these sanitation vehicles are unmanned vehicles. Only a few large vehicles have sanitation suits on them.
Sanitation workers in work clothes, and they are engaged in some light work.
You will also occasionally find some sanitation workers wearing sanitation work clothes on the streets. They do not clean the floor like traditional sanitation workers. Instead, they hold control equipment and operate the sanitation equipment to make up for the shortcomings of these intelligent and unmanned equipment.
insufficient.
It is also because of the 24-hour non-stop operation of these unmanned sanitation vehicles that the streets in Anxi are very clean, and there is no dust or garbage at all. Even if there is garbage, it will be cleaned up in a short time.
clean.
Such a scene really shocked all the foreign media reporters. In their view, this distant eastern city could be so advanced. It seemed that they had entered a future city that only appeared in movies and TV series, and other cities on the earth.
The places are two completely different worlds.
And everything here has a very close relationship with Haoyu Technology in this city. It can be said that Haoyu Technology and Wu Hao changed this city.
It's still some time before Haoyu Technology's summer new product & new technology launch conference, so these reporters decided to go deep into every corner of the city to explore everything related to Haoyu Technology.
So these foreign media reporters began to look for interviewees they were interested in based on their own interests. In this regard, Anxi City is also very happy to show these foreign media reporters the development results of Anxi in recent years. On the one hand, it is to show overseas the recent development results.
The development achievements in the past few years are also to reverse some of the biased views of overseas media and people towards our country and Anxi.
Under the leadership of the publicity department staff, these media reporters naturally saw a lot of things they had not seen before.
For example, in the sanitation system, the unmanned sanitation vehicles they see on the street are just a basic link in the entire city's intelligent sanitation engineering system.
For a large city, a huge amount of solid waste is generated every day, reaching thousands or even tens of thousands of tons. How to deal with these wastes has always been a topic of debate among all parties.
There are three main methods of solid waste cleaning used by most countries and cities.
First of all, the first one is to recycle renewable resource waste. However, in this regard, the recycling rate of this part of waste in various countries has always been very low. Only a rough screening will be carried out to recycle and dismantle some valuable waste.
Processing, and then resource utilization, but this utilization rate is a very small part of the total amount of garbage, and can even be said to be negligible.
As for European and American countries, they have done an even better job in this area. They have concentrated a lot of large solid waste. However, they did not recycle and reuse it, but packaged it and shipped it to third world countries and handed it over to these countries for dismantling.
It decomposes and disposes these solid wastes for free for them. It is tantamount to forcing the waste it produces on other countries, causing serious pollution to these countries and regions.
In the early years, we were also the exporter and processor of garbage from these countries. Later, we realized the dangers of these foreign garbage, so we banned the entry of these foreign garbage. So these countries, after a few curses, could only say
Looking for other countries and regions, such as Southeast Asia, Africa, South America, etc. Judging from the exposed photos and news, some countries and regions are already filled with solid waste from all over the world, even piled thousands of meters high.
The mountain of garbage has become a sea of garbage.
Although countries around the world are now advocating to strengthen the recycling and reuse of solid waste, the actual recycling rate is so low that it can be described as a piece of cake.
The second way is centralized burial, which is also the most important and main way to deal with solid waste. There are such large landfills around many cities, and a large amount of municipal solid waste is transported here every day.
, and then buried.
Although these landfills have undergone special treatment, over time, rainwater penetration will cause harmful elements in these garbage to contaminate nearby groundwater, harming the surrounding ecological environment and human health. And these buried garbage,
It needs to go through a long degradation period, which may take hundreds, thousands, or even tens of thousands of years, before the earth can metabolize it.
The third method is centralized incineration. This is an ancient method of garbage removal, and it is also a new method of garbage removal that has been actively developed in various places in recent years.
In the early years, centralized incineration was carried out to deal with these garbage. However, at that time, the knowledge was burned on the spot, and other things were not taken into consideration at all. The harmful gases produced by the incineration of these garbage can be said to seriously pollute the entire air, and even easily
It can cause some respiratory diseases. As for the ashes after incineration, they are also polluting. They will penetrate into the ground with rainwater and pollute groundwater. They will also be collected into rivers with rainwater, polluting water sources.
People quickly realized this, and then carried out centralized incineration, concentrated it in special devices for incineration, filtered the air after incineration, and processed the incineration ash, so as to reduce pollution.
In recent years, with the strengthening of environmental sanitation concepts, especially the depletion of carbon emissions and mineral resources, people have begun to notice that these garbage are actually a resource that can be used. In the past, these garbage were burned in vain, which is a pity.
.
Why not use these garbage to incinerate and generate electricity? This is much more environmentally friendly than thermal power stations that just burn coal.
So various cities began to build some thermal power plants in the surrounding area specifically for burning garbage. Such thermal power plants can process a lot of garbage every day and convert them into electricity to continue to serve the city. Some cities even use garbage.
The heat energy generated by incineration is used to provide heating for urban residents.
