What Is Solids Control?

Solid waste refers to solids, semi-solids, and gaseous items, substances, and laws placed in containers that have lost their original use value or were abandoned or abandoned although they did not lose their use value. Articles and substances that are included in waste management as required by administrative regulations. Liquid wastes that cannot be discharged into water bodies and gaseous substances in containers that cannot be discharged into the atmosphere. Because it is more harmful, it is generally classified as a solid waste management system.

Solid waste refers to solid and semi-solid wastes that pollute the environment and are discarded by humans during production, construction, daily life, and other activities. They cannot be used at a certain time and place.

The environmental engineering terminology is defined as follows from the Environmental Protection Standard of the People's Republic of China "Environmental Engineering Terminology" (HJ2016-2012).

English: solid waste

Chinese definition: solid, semi-solid and gaseous articles, substances and laws and administrative regulations in the production, living and other activities that have lost their original use value or have been abandoned or abandoned without losing their use value Provisions for articles and substances included in the management of solid waste. ^[1]

There are various classification methods of solid waste, which can be divided into organic waste and inorganic waste according to their composition; solid waste, semi-solid waste, and liquid (gaseous) waste according to their form; according to their pollution characteristics, they can be divided into hazardous waste and General waste, etc .; can be divided into mining, industrial, urban living, agricultural and radioactive according to their source.

In addition, solid waste can be divided into two categories: toxic and non-toxic. poisonous

Solid waste is environmental

First of all, it is necessary to start from the source of pollution, improve or adopt newer cleaner production processes, and minimize or not discharge waste. ^[2]

Solid waste refers to the solid, semi-solid waste that is produced by people in production, construction, daily life and other activities and cannot be used or is temporarily unusable by the producer.

According to the causes of municipal solid waste, it can be divided into the following four categories:

(1) Industrial solid waste

Industrial solid waste is produced during industrial production and processing. Various waste residues discharged into the environment,

The major environmental hazards of solid waste are reflected in the following aspects:
(1) Occupied land If the domestic garbage of the city cannot be treated and disposed of in a timely manner, it will occupy farmland, destroy agricultural production, as well as landforms, vegetation, and natural landscapes.
(2) If improperly treated solid waste in contaminated soil, harmful components can easily flow into the soil through surface runoff, killing soil microorganisms and destroying the structure of the soil, resulting in deterioration of soil health.

(3) Polluted water solid waste can drift into human surface runoff with natural precipitation or wind, and then flow into water bodies such as rivers and lakes, causing pollution of surface water.

In addition to the above routes, some solid waste may cause special damage such as combustion, explosion, contact poisoning, and corrosion. In addition, side body waste may indirectly harm human health through plants and animals, such as

According to the provisions of the Law on Prevention and Control of Environmental Pollution by Solid Waste, the scope of application of the Law on Prevention and Control of Environmental Pollution by Solid Waste includes the following four aspects: ^[2]

Charges for hazardous waste disposal

(Reporter Su Jingyue) The Taiyuan Municipal Price Bureau's Price Appraisal Committee reviewed and approved the Taiyuan City Opinions on Hazardous Waste Disposal Charges, which set the highest price for hazardous waste treatment: incineration, 7 yuan / kg; materialization Handling, 6 yuan / kg etc.
In order to completely solve the problem of environmental pollution caused by hazardous wastes, the State Council issued in 2003 the National Plan for the Construction of Disposal Facilities for Hazardous Wastes and Medical Wastes, which specified the Taiyuan hazardous waste disposal projects. The project is one of the 31 hazardous waste disposal sites nationwide identified in the Plan and the only comprehensive hazardous waste disposal site in the province. The main body of the project has been completed.
According to the practice of the running project and the characteristics of the disposal process of the project, in accordance with the principles of simplicity, effectiveness and easy operation, Taiyuan has formulated the highest standards for hazardous waste treatment processes as required: incineration treatment, 7 yuan / kg; 6 yuan / kg; solidification / stabilization treatment, 4 yuan / kg; safe landfill treatment, 3.5 yuan / kg; waste chemical reagents, 100 yuan / kg; highly toxic chemicals, 1,000 yuan / kg. For the disposal of special hazardous waste, the specific disposal price shall be agreed between the hazardous waste disposal unit and the unit entrusted to dispose of the hazardous waste. Charges of 0.5 kg for highly toxic chemicals are charged at 0.5 kg; according to relevant state regulations, small and micro enterprises implement preferential policies. ^[5]
