The environmental technology group, there are six main types of solid waste disposal:

Compaction technology: through the waste reduction, reduce transportation costs and extend the life of landfill pretreatment technology.

Crushing technology: reduce waste shape, eliminate voids, uniform size, texture, mainly impact, crushing, cutting, crushing, crushing, friction, crushing, low-temperature crushing and mixed crushing.

Sorting technology: an important way to realize the reduction of solid waste recycling, sorting through the useful fully elected to use, will be fully separated harmful; another is the different granularity level waste to be separated, the basic principle is to use some of the material sorting of the differences, will leave the. Sorting includes manual picking, screening, gravity sorting, magnetic separation, eddy current sorting, optical sorting, etc..

Curing processing technology: adding curing to substrate waste, the hazardous solid waste containment or fixed a harmless in an inert substrate of curing process can be divided into heavy solidification, asphalt solidification, glass curing and curing glioma.

Incineration and pyrolysis: the process of treating solid waste by high temperature decomposition and deep oxidation. The advantage is that a large amount of harmful waste materials are decomposed into harmless substances.

Biological treatment technology: decomposition by microorganisms of organic solid waste to make it harmless to the organic solid waste into energy, food, feed and fertilizer, can also be used for the extraction of metals from waste and waste, is the effective method of curing technology of the waste of resources.

The environmental technology group (resources) of pyrolysis and gasification of waste disposal system mainly includes: receiving and feeding system, pyrolysis and gasification furnace system, waste heat utilization (power) system, flue gas purification treatment system, ash collection system, leachate treatment system, automatic control system etc.. The technology uses the principle of high temperature pyrolysis and gasification, and does not need to add any auxiliary fuel in the process of processing. It can deal with all kinds of domestic waste continuously and stably. The temperature of the gasification chamber can be stabilized at 950-1100 degrees. With its internal pyrolysis, gasification chamber, combustion chamber and sedimentation chamber of the unique structure design, without additional desulfurization dust removal equipment, flue gas can be directly discharged. The whole equipment running process is fully automatic controlled.

The kitchen waste collection and transportation system of equipment: kitchen waste collection vehicles, dynamic monitoring.

Livestock manure treatment: multi species organic matter combined anaerobic fermentation, biogas engine power generation.

Biomass treatment of dead livestock and domestic waste.

Energy farm: Green Platycodon root as raw material, biogas production, biogas power generation and reuse of isolated.

The construction waste disposal and resource utilization of construction waste, will be regarded as "resources", abandon the traditional "construction waste", through the construction waste "resources", the construction waste turning waste into treasure, in solving the problem of environmental pollution caused by construction waste at the same time, have certain economic benefits. National Environmental Science and technology group launched:

1. The use of construction waste recycled by crushing, screening, magnetic separation, winnowing and washing equipment, the construction waste recycling or recycling, making a low standard building aggregate.

2. Complete sets of equipment for construction waste disposal.

There are three main types of waste incineration technology in national environmental protection science and Technology Group: layered combustion technology, fluidized bed combustion technology and rotary combustion technology. The garbage is burned in the incinerator to release heat energy, and the waste heat recovery can be used for heating or generating electricity. After the flue gas is purified, a small amount of residual residue is discharged for landfill or other purposes. Incineration technology is characterized by large amount of treatment, good volume reduction, harmless and complete, and the recovery of heat energy. Therefore, incineration treatment of municipal solid waste is an effective way of harmlessness, reduction and recycling.

The environmental technology group according to the garbage composition and characteristics, follow the "classification and gradual reduction, to treat waste and waste" principle, combined with the local industry, economy, science and technology, geography, ecological environment and human conditions, optimal combination of waste disposal methods, the integration of industrial chain, the establishment of waste material management (energy) chain the information chain and the interests of the chain, the classification of waste source reduction and emission control, material utilization, energy utilization and implementation of solid waste landfill disposal, properly handle and specialized, intensive processing.

The environmental technology group using cutting-edge technology, straw and livestock manure in rural areas, kitchen waste and other agricultural waste anaerobic fermentation to produce biogas, while landfill landfill gas produced by power cogeneration, and CNG can be used for vehicle gas purification. The use of clean energy has effectively protected the ecological environment.

Environmental protection science and technology group of national environmental protection science and technology group, make the sanitation system change from the traditional traditional government operation mode to modern science and technology management. The use of "integration, cluster and intelligent sanitation" will enable the original unreasonable people, work, machines, materials, fees, scientific unity, coordination, wisdom management, and reasonable matching. Through integration and allocation, the overall operation and management level of sanitation work has reached the international first-class level.

The environmental science and technology group to "particle recombinant technology, bioremediation, remediation and leaching technology" as the core, the pollution situation and characteristics of different site, to provide and implement environmental safety, risk control, economical repair technical route, full protection of human health and environmental safety.

The main process of sludge treatment in State Environmental Protection Science and technology group is:

1. concentration: preliminary dehydration and reduction of sludge volume. After the sludge is concentrated, it can be convenient for subsequent treatment. The common methods of concentration include gravity sedimentation, floating enrichment and so on.

2. Digestion: further reduce the amount of sludge, facilitate treatment, reduce environmental harm and improve the value (recovery of methane generated by further use). Commonly used digestion method is through microbial metabolism, sludge decomposition, removal of special odor, killing harmful substances, such as parasites, eggs and so on.

3. Dehydration and drying: easy transportation. After the first two steps, the water content is thrown away. It needs to be dried by natural evaporation or mechanical dehydration.

4. Incineration: completely removes moisture and organic impurities. Step, water is still around 13%, toxic substances commonly used incineration treatment of water and some are not suitable for manure or hard substance use.

5. Final treatment: toxic substances such as heavy metals are often treated with deep burial methods.
