A must for foreign homes, no one at home cares Why is the garbage disposer unsatisfied

Domestic garbage classification has also been going on for several years, and now it can be regarded as roughly implemented. When garbage sorting was first implemented, the garbage disposer took advantage of the situation for a while, but it didn't take long to quietly disappear... A few years later, I saw garbage disposers at exhibitions such as AWE, but garbage disposers were not hot at all like they were back then.

Looking abroad, garbage disposal can be described as the standard equipment in the kitchen. It is said that the penetration rate of garbage disposal in the United States and Europe has reached more than 90%, and the penetration rate in Japan and South Korea has reached 100% (in fact, it must be almost interesting). On the other hand, in China, garbage disposers have always been a sober "ordinary people are not willing to use it, and rich people do not pretend much". Why is the garbage disposer unsatisfied? Let's briefly discuss this matter today.

1 How technical is the garbage disposer?

After a table of meals, all that remains is the messy kitchen and the cold soup and melon husks that clog the sink. And the garbage disposal is born to solve these kitchen leftovers!

The garbage disposer, to put it bluntly, is a special "grinder" for kitchen waste, connected between the sink and the sewer, throws the kitchen waste in, and the machine will crush them, grind them, and then flush them down the sewer pipe. This product says that the principle is quite simple, most people can understand it at a glance, but in fact it can not solve all kitchen waste, which is also the most important reason why it cannot adapt to the domestic kitchen environment, let's talk about it in detail.

2 The garbage disposal is not satisfied, not its fault, but the countrymen are too hardworking!

Why has garbage disposal not been widely promoted in China? In fact, after thinking about it, I found that there are several reasons:

First, the kitchen waste disposer was originally designed according to the diet and residential structure of European and American countries, and has long become a configuration of many family kitchens in the United States, but for domestic consumers, there is no concept of garbage disposer from the beginning, and it is too limited for the improvement of quality of life! Washing clothes, washing dishes, and taking out garbage is a natural and natural thing, do you need to spend thousands of oceans to buy a lazy thing?

Second, the cooking method of the Chinese is heavy oil, the diet structure is more complicated, some old communities and old houses have narrow sewer pipes, unable to bear the kitchen waste discharged into the pipeline, so the use experience is not ideal, often cause blockage. In addition, the garbage disposer can not handle a large amount of oil, bones, etc., so the garbage that can be cleaned up is actually relatively limited, if you can't clean up all the kitchen waste, then what difference does it make if you don't install it?

Third, in the first and second-tier cities, a very large number of young people are renting houses, and renting a house decides not to buy such products, water heaters, refrigerators, air conditioners, range hoods These landlords will generally configure, kitchen appliances such as ovens can be taken away, and those who pursue a little quality of life will also buy, but garbage disposers, installation is more troublesome, in the rental will not be too considered. The current rental population in China still accounts for a large part, and if these rental parties will not use it, it also indirectly makes the garbage disposer lose a lot of market space.

Fourth, the domestic municipal sewage treatment capacity is not perfect, can not be one-size-fits-all, according to the research report of Tongji University, when the penetration rate of garbage disposal is greater than 10%, the sewage organic load will have an impact on the urban sewage treatment system.

3 Are garbage disposal environmentally friendly? It's not necessarily environmentally friendly

It is always said that garbage disposal is convenient, but have you ever wondered if garbage disposal is environmentally friendly? Our domestic implementation of garbage classification is to promote the development of environmental protection in the mainland, among which the most environmentally friendly way to treat kitchen waste is to recycle and reuse it as much as possible. What the garbage disposer does is to break the garbage and discharge it into the sewer, and eventually become a sediment, without any possibility of reuse, and even increase the burden of septic tanks and sewage treatment plants to a certain extent.

Now the general community drainage system will have its own septic tank, and the discharged domestic sewage will enter the septic tank through the pump. Several septic tanks undergo a floating, sedimentation process that discharges sewage containing fewer solids into pipelines to sewage treatment plants, where it is treated into grey water through a similar process. Sediment and floating debris, whether in a septic tank in a community or a treatment tank in a sewage treatment plant, needs to be cleaned. Shredded waste, even kitchen waste, will increase the number of times it takes to clean up storage and increase the burden of disposal.

4 Where does Chinese of kitchen waste go?

In the past, kitchen waste was basically used to feed pigs. I always throw the leftovers directly into the pigsty, which is the best representative of the way to turn kitchen waste into treasure.

However, now that we have entered the city, we have begun to become city people, where is our kitchen waste now? In fact, there are no more than 3 types of cooking waste disposal methods. 1. Animal conversion: use poultry (large animals), earthworms, fruit flies and other animals to convert kitchen waste into animal nutrition and animal manure, and then dispose of animals and their feces reasonably. 2. Bioconversion: use the action of microorganisms to convert kitchen waste into humus, biogas, alcohol, etc., or dry kitchen waste (biological drying). 3. Physical and chemical methods: mechanical dehydration, waste heat drying, solar drying, (drying kitchen waste, humus) incineration, etc.

5 Write at the end

Garbage disposers can indeed free their hands to a certain extent and can alleviate many kitchen waste problems, but for Chinese families, it is not omnipotent and has certain limitations. Of course, I hope that after the national awareness of environmental protection is cultivated, all efficiency will come first, and more professional people will do more professional things. From the perspective of garbage classification, reduce the time cost of personal garbage classification and hand it over to a more professional garbage treatment plant to deal with. From the perspective of sewer pipe discharge, strengthen the pipeline sewage discharge capacity and strengthen the treatment capacity of sewage treatment plants. Using technology to solve the problems of garbage disposal and environmental protection is the way of the future.
