What is a continuous feed garbage disposal: The products of people’s activities in everyday life, in transport, in the fields of industry and economy, which are not used directly in the places of their formation, or are used as raw materials in other industries or during processing, are called waste. They can be material residues, raw waste, residual semi-finished products that are formed in the process of production and lose their useful physical qualities (in whole or in part). During the processing of raw materials, during the extraction, enrichment of minerals, products are also formed that are considered production waste, because this production is not involved in the production of these products. Unsuitable for further use for its intended purpose, decommissioned machines, various tools, household products are called consumption waste. What is a continuous feed garbage disposal?

The possible use of the waste defines them as recyclable and not recyclable. In relation to utilized waste, there are all kinds of technologies for their processing, accompanied by their involvement in the turnover of the economy or industry. For non-recyclable waste, such technologies do not exist today. The classifier of industrial waste, the calculation according to the hygienic values of the substance or the experimental path determine the belonging of the waste to certain groups.

Wastes of all groups and classes are divided into:

  • solid waste
  • pasty
  • liquid
  • dusty (gaseous)

Waste from the solid group includes unsuitable containers (metal, wood, cardboard, plastic), cleaning materials, used filter elements and filter materials, polymer pipe cuttings, and cable product residues. The pasty group waste includes sludge, resin, filter cake and cake from filters and sumps after cleaning the tanks from heat exchangers. Liquid waste may be wastewater, which due to its high toxicity is not subject to biological treatment. Dusty (gaseous) wastes are emissions from degreasing sites in the metallurgical industry, when painting equipment.

Waste belonging

To the chemical stability group divides them into explosive, self-igniting, decomposing (with the release of toxic gases), stable. Further, the waste is divided into water-soluble waste and waste that does not dissolve in water. What is a continuous feed garbage disposal? By its origin, the waste is divided into organic, inorganic waste, as well as mixed. Industrial wastes are often chemical wastes, which are heterogeneous, complex mixtures of multicomponent that have all kinds of physicochemical properties and can pose a chemical, toxic, corrosive, biological effect, as well as a fire hazard and explosion hazard. Waste can be classified according to various characteristics: by their chemical characteristics, by their technological formation, on their possible processing in the future and their further use. In Russia chemical wastes are divided into four hazard classes, which are associated with the costs of their processing and disposal:

Extremely hazardous waste

This includes waste containing mercury and its compounds, as well as mercuric chloride, chromic acid and potassium cyanide, antimony. Toxicity to mercury compounds gives the harmful effects of the Hg2 + ion. Mercury enters the human and animal organism not in the form of ions, but when combined in the blood with protein molecules, forming metalloproteins after such compounds. In case of poisoning with the above-mentioned substances, a violation of the functions of the central nervous system occurs, damage to the kidneys up to their complete failure, which subsequently leads to the death of the victim;

Highly hazardous waste

This includes wastes containing copper chloride, oxalic copper, antimony trioxide and lead compounds. Their toxicity is manifested, like any poisoning process, accompanied by anemia, a stomach ulcer, changes in the liver and kidneys, hemorrhage in the internal organs, death;

Moderately hazardous waste

This includes waste containing lead oxides, nickel chlorides, carbon 4-chloride. With prolonged exposure to the body, the number of red blood cells decreases;

low-hazardous waste with the content of magnesium sulfates, phosphates, zinc compounds. This includes waste generated by the flotation method of mineral processing where amines are used. Once in the body, phosphate dust leads to the development of pneumosclerosis, a reduction in the bronchi and blood vessels. Contact of human skin with phosphates can cause dermatitis, characterized by rash, burning and itching;

the waste is neither hazardous nor toxic.

Problems associated with the protection of the environment today occupy one of the first places among the urgently important tasks of mankind. Emissions from industrial enterprises to the atmosphere today reach such proportions that the tolerances for sanitary standards in relation to the level of pollution are several times exceeded. Tons of waste enters the biosphere in solid, pasty, liquid, gaseous form, thereby causing invaluable damage to nature, undermining its resources. In this regard, it became necessary to develop and implement new modern and safe methods for solving the problem of ridding the biosphere of its pollution by industrial and consumer waste. In order to choose a more rational way to solve this problem, waste is preliminarily recorded and evaluated.

Conclusion

After the collection of waste, they are evaluated. Depending on this, the waste is recycled, disposed of or disposed of. Waste materials that are useful in the future are recycled.

For example, used oils are cleaned from corrosion products, wear, cleaned from suspended particles, thermal decomposition products, after which additives are added. As a result, oils are obtained for repeated use. Waste rubber products, like car tires, are crushed, then sent to a new manufacture of the same products. Mercury lamps are subjected to demercurization to produce mercury. Spent nuclear fuel from nuclear plants is reprocessed at radiochemical plants. With such processing, plutonium and uranium are obtained, using them in the future in nuclear reactors.
