With the increasing improvement of people's living standards, more and more household waste is generated in their daily lives, and the treatment of waste is related to the beautification of cities. Let's take a look at the waste recycling and disposal methods in various countries. Spain, small waste also has great use. Madrid's complex and comprehensive infrastructure and services for waste classification, collection, transportation, treatment, and renewable energy development and utilization.

Combustible waste will undergo high-temperature incineration here, with the generated gas used for power generation and the heat used for heating. The slag ash and dust will be sent to the "ash melting facility" to manufacture building materials, and metals such as iron and aluminum will be recovered. The harmful gases generated from incineration waste will be discharged after treatment.

That is to say, the main reason for the difficulty in handling large pieces of waste furniture is the high cost of disposal and the low value of the mall. Relying solely on the principles of shopping malls is difficult to solve this problem. The problem of dealing with large pieces of waste furniture has been long-standing for many years. It is not only a problem for families in Kunming, but also a global problem.

The plant extraction technique used for deodorants extracts useful ingredients from the roots, stems, leaves, and flowers and fruits of various plants. Its effectiveness under radiation effects improves the activity of plant fluids, and it can quickly undergo chemical reactions such as polymerization, substitution, displacement, and adsorption with various harmful and odorous molecules. It is effective in removing odorous gases such as hydrogen sulfide, methane, methyl mercaptan, ammonia, and other volatile organic compounds (VOCs) for purification.

The principle of biological phosphorus removal is to use so-called phosphorus accumulating bacteria to absorb excessive phosphorus under aerobic conditions, that is, phosphorus in water is enriched in active wastewater; Under anaerobic conditions, phosphorus can be released from activated sludge, which mainly exists in the supernatant. Then, it is discharged from the activated sludge after phosphorus accumulation and from the phosphorus containing supernatant to separate the phosphorus from the treatment system, achieving the intention of biological phosphorus removal. In addition, during the biological phosphorus removal process, BOD also undergoes differentiation. Under anaerobic conditions, the organic matter in the wastewater forms acetic acid through the effect of acid producing bacteria. Under these conditions, polyphosphate accumulating bacteria differentiate the polyphosphate and release some of the energy for their own survival needs, while the other part is used to absorb acetic acid H and electrons, which are stored in the form of PHB inside the cell, and inorganic phosphorus is discharged outside the cell. Under aerobic conditions, polyphosphate accumulating bacteria differentiate PB and release energy, with a portion used for their own growth and reproduction, and another portion used for the absorption of inorganic phosphorus, forming polyphosphate storage within cells.

The concentration of ammonia nitrogen in drinking water rarely exceeds 3mg/L. In some rivers in China, the concentration of ammonia nitrogen is between 0.17-4.41m/L. When the nitrification effect weakens in winter, the concentration of ammonia nitrogen in surface water shows a seasonal increase. Usually, ammonia nitrogen in water supply does not cause significant direct damage, but ammonia is an electron donor for the proliferation of autotrophic bacteria. In treatment plants and water distribution systems, when the concentration of ammonia nitrogen reaches 0.25mg/L, it is sufficient to promote the growth of nitrifying bacteria. However, some volatile compounds and ammonia release during the metabolism process of nitrifying bacteria can cause odor problems.
