Your question "from the solid waste treatment of the "three" point of view, that the most should develop that kind of treatment technology?" You can see that "treatment" refers to the former item, here I just talk about my attitude, just for reference.
The three "treatment" technology has its own advantages and disadvantages, there is no best only "better", this comparison is based on the actual local situation.
For example, for arid areas with little rain (deeper water table, more abundant land resources), such as my beautiful hometown of Xinjiang. Land sanitary landfill (landfill) is not a viable option, as long as the focus on preventing waste leachate contamination of groundwater and surface water can be, but also can produce a certain amount of towards the gas for power generation. This method is also the more common international waste disposal methods, accounting for more than 80% of the amount of municipal waste disposal; but for the land resource constraints in the region this approach is often caught in a situation of overstretch, such as Beijing has been built in the garbage 10 landfill is basically in the state of closure and closure of the state of the supply to the newly set up landfill land is very limited, most of the economically developed areas of China said the city Most of the cities in economically developed areas in China are facing the same problem, so incineration is a newly proposed solution for many cities;
The advantage of incineration is that it is an obvious "minimization", and the volume of incinerated garbage usually accounts for 5-20% of the original garbage, and it is also safer from the point of view of hygiene, so most of the medical garbage is now treated in the way of incineration, but many people still have the same problem, which is that it is not a good solution. Of course, many people also speak from the perspective of energy utilization, "the story of garbage power generation", although our country's garbage due to the low calorific value, high water content are not enough to maintain their own combustion level. But there are corresponding disadvantages of incineration, which is why the Western developed countries from the late 80's began to gradually shut down the "incinerator" reasons: 1, will produce highly toxic "dioxin", for which there is no feasible online real-time monitoring technology. Therefore, there is no reliable control technology for dioxin, which is why most people oppose the construction of waste incinerators around their own reasons; some relevant experts to provide data are mostly unreliable, mainly because it will involve their own huge profits. 2, in addition to dioxin, there are also atmospheric and water pollution.
3, the composting of garbage, currently in a certain sense also belongs to the beautiful illusion, because the garbage suitable for composting to food waste is mainly high water, high salt and a variety of organic and inorganic solid particles are too much directly caused by the composting product is difficult to use for farmland, because it will lead to salinization of farmland, slagging, and even some of the toxic components of the farmland, which is one of the biggest problem! This is one of the biggest problems. China invested heavily in building a large number of compost processing sites all over the country in the 1990s, but only a few of them are barely holding their own at the moment.
4, resource is the best way, but because of economic and technical reasons, the part of urban waste resource is relatively small, this aspect of the problem is not a short period of time can be solved, to put it vulgarly, this is a systematic problem.
Of course, there are many other problems, here will not do too much introduction, just to emphasize the point that there is no best garbage disposal, only better, that is, after the comparison to know what is more suitable only, each technology needs to be developed, need to be further improved.
Wishing you a good summer!
