工业固体废物贮存量 指以综合利用或处置为目的,将固体废物暂时贮存或堆存在专设的贮存设施或专设的集中堆存场所内的数量。专设的固体废物贮存场所或贮存设施必须有防扩散、防流失、防渗漏、防止污染大气、水体的措施。
工业固体废物处置量 指将固体废物焚烧或者最终置于符合环境保护规定要求的场所,并不再回取的工业固体废物量(包括当年处置往年的工业固体废物累计贮存量)。处置方法有填埋(其中危险废物应安全填埋)、焚烧、专业贮存场(库)封场处理、深层灌注、回填矿井等。
工业固体废物排放量 指将所产生的固体废物排到固体废物污染防治设施、场所以外的数量,不包括矿山开采的剥离废石和掘进废石(煤矸石和呈酸性或碱性的废石除外)。
“三废”综合利用产品产值 指利用“三废”(废液、废气、废渣)作为主要原料生产的产品价值(现行价);已经销售或准备销售的应计算产品价值,留作生产自用的不应计算产品价值。
“三废”综合利用产品利润 指利用“三废”(废液、废气、废渣)生产的产品,销售后所得到的利润。
Volume of Industrial Waste Water Discharged refers to the volume of industrial waste
water discharged, through all outlets, to the outside of industrial
enterprises, including waste water produced, direct-cooling water, underground
water from mines that does not meet the standard of discharge, and the domestic
sewage mixed up with industrial waste water when discharged, but excluding
discharged indirect-cooling water.
Volume of Waste Water up to
the Standard for Discharge
refers to the volume of discharged industrial waste water that, with or
without treatment, has come up to the national or local standards for
discharge.
Volume of Treated Industrial
Waste Water refers
to the volume of industrial waste water after being treated and purified
through various water treatment facilities in the reference period, including
the volume discharged or recovered after being treated. The volume of waste
water that fails to meet the national or local standards after treatment is
also included. If there are treatment facilities both at the outlets of
workshops and at the outlets of the factory, and the same volume of waste water
has been treated twice, duplication should be avoided in the calculation of the
volume of treated industrial waste water.
Volume of Waste Industrial
Gas Emission refers
to waste gas emitted from burning of fuels and from production process in the
area of the factory, and is measured by 10000 standard cubic meters during the
reference period under normal condition (273k, 101325Pa).
Volume of
Industrial Sulphur Dioxide Discharged refers to the volume of sulphur dioxide
discharged to the air in the process of fuel burning or in the production
process during the reference period.
Volume of Industrial Soot Discharged refers to the volume of solid soot in
the smoke discharged in the process of fuel burning in the area of the factory.
Industrial Dust
Discharged refers
to the total weight of solid dust discharged by industrial enterprises in the
production process, during the reference period, such as dust of refractory
materials from iron plants, dust from coke-screening system or from sintering
machines of coking plants, dust from lime kilns, cement dust from building
material enterprises, etc., but excluding smoke and dust discharged by power
plants.
Volume of Industrial Solid
Wastes Produced refers to the
total volume of solid, semi-solid or high concentration liquid residue produced
by industrial enterprises in their production process, during the reference
period, including dangerous wastes, residues from melting, slag, powdered coal
ash, gangue, chemical residues, tailings, radioactive residues and other
residues, but excluding stripped or dug stones in mining (except gangue and
acid or alkali stones which are stones washed or soaked by water with a pH
value smaller than 4 or larger than 10.5)
Volume of Industrial Stored
up Solid Wastes refers
to the volume of industrial solid wastes temporarily stored up or piled with
special facilities or piled in the special sites for the purpose of utilization
or treatment in future during the reference period. The special facilities or
special sites for storing up solid wastes should have the measures against
spreading or being washed away to other places, permeating the soil or causing
air pollution or water contamination.
Volume of Industrial Solid
Wastes Treated refers to
solid wastes disposed of in a non-recoverable place that meet the requirement
of environmental protection, during the reference period, such as burying (the
dangerous wastes should be buried safely), burning, piling in designated sites,
pouring water into the deep strata, filling of old mines, etc. (including
treatment of solid wastes piled up in the previous years).
Volume of Industrial Solid
Wastes Discharged refers to the
volume of industrial solid wastes produced and discharged at the places outside
the special facilities or special sites for preventing against pollution,
excluding stripped or dug stones in mining during the reference period.(except

Output Value of Products
Made from Utilization of Waste Gas, Waste Water and Industrial Solid
Wastes refers to the
value of products (calculated at current prices) made by industrial enterprises
using recovered waste water, waste gas or solid wastes as main raw materials
during the reference period. Only the value of the products, which have been
sold or are ready to be sold, should be included. The value of the products,
which will be used in the production of the enterprises, should not be
included.
Profit Obtained from
Utilization of Waste Gas, Waste Water and Industrial Solid Wastes refers to profit
obtained from selling or own-consumption of products made by industrial
enterprises using recovered waste water, waste gas or solid wastes as main raw
materials.
