Pollution control standard for the hottest hazardo

2022-07-30
  • Detail

Pollution control standards for hazardous waste incineration in order to implement the environmental protection law of the people's Republic of China and the law of the people's Republic of China on the prevention and control of environmental pollution by solid waste, strengthen the pollution control of hazardous waste, protect the environment and protect human health, the State Environmental Protection administration has formulated pollution control standards for hazardous waste incineration. The full text is as follows:

1 scope

starting from the needs of environmental pollution prevention in the process of hazardous waste treatment, this standard specifies the site selection principles of hazardous waste incineration facilities, basic technical performance indicators of incineration, the maximum allowable emission limit of air pollutants discharged by incineration, the disposal principles of incineration residues and corresponding environmental monitoring

this standard is applicable to the design, environmental impact assessment, completion acceptance and pollution control management during operation of hazardous waste incineration facilities other than explosive and radioactive ones

2 reference standard

the provisions contained in the following standards, which are cited in this standard, constitute provisions of this standard and have the same effect as this standard

ghzb1-1999 environmental quality standard for surface water

gb3095-1996 ambient air quality standard

gb/t16157-1996 determination of particulate matter in exhaust gas from fixed pollution sources and sampling methods for gaseous pollutants

gb15562.2-1995 graphical signs for environmental protection solid waste storage (disposal) Site

gb8978-1996 integrated wastewater discharge standard

gb12349-90 industrial enterprise boundary noise standard

hj/t20-1998 technical specification for sampling and sample preparation of industrial solid waste

when the above standards are revised, the latest version shall be used

3 the term

3.1 hazardous waste

refers to the waste with hazardous characteristics listed in the national hazardous waste list or determined according to the national hazardous waste identification standards and methods

3.2 incineration

refers to the process of incinerating and burning hazardous wastes to decompose them and make them harmless

3.3 incinerator

refers to the main device for incineration of hazardous wastes

3.4 incineration capacity

weight of hazardous waste incinerated by incinerator per hour

3.5 incineration residues

refer to the combustion residues, fly ash and solid substances produced by tail gas purification device after incineration of hazardous wastes

3.6 ignition loss rate

refers to the percentage of the mass of incineration residue reduced by ignition in the mass of original incineration residue. The calculation method is as follows:

p = (a-b)/A × 100%

where: P - rate of loss on ignition,%

a - mass of original incineration residue after drying at room temperature, G; B - mass of incineration residue cooled to room temperature after burning at 600 ℃ (soil 25 ℃) for 3h, G

3.7 flue gas residence time

refers to the residence time of flue gas generated by combustion from the last air injection port or burner outlet to the heat exchange surface (such as waste heat boiler heat exchanger) or flue cold air injection port

3.8 incinerator temperature

refers to the temperature at the outlet center of the incinerator combustion chamber

3.9 combustion efficiency (CE)

refers to the percentage of the concentration of carbon dioxide in the flue gas and the sum of the concentration of carbon dioxide and carbon monoxide

is expressed by the following formula:

ce = CO2/(CO2 + CO) × 100%

where: [CO2] and [CO] - are the concentrations of CO2 and CO in the exhaust after combustion respectively

The organizer of the exhibition also stated that the

3.10 incineration removal rate (DRE)

at the entrance of exhibition visitors in area a and area B refers to the percentage of an organic substance reduced after incineration. Expressed by the following formula:

dre = (WI - Wo)/wi × 100%

where: wi - weight of an organic substance in the incinerated substance

wo - the sum of the weight of organic substances corresponding to WI in flue gas exhaust and incineration residues

3.11 dioxins

polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans

3.12 dioxin toxic equivalent (TEQ)

dioxin toxic equivalent factor (TEF) is the ratio of affinity between dioxin toxic congeners and 2,3,7,8-tetrachlorodibenzo-p-dioxin pairs. Dioxin toxic equivalent can be calculated by the following formula:

teq = ∑ (concentration of dioxin toxic congener × TEF)

3.13 standard state

refers to the gas state when the temperature is 273.16k and the pressure is 101.325kpa. The emission limits of various pollutants specified in this standard refer to the concentration after conversion with 11%o2 (dry air) as the conversion benchmark under the standard state

4 technical requirements

4.1 site selection principles of incineration plants

4.1.1 all types of incineration plants are not allowed to be built in class I and class II surface water environmental quality functional areas specified in ghzb1 and class I ambient air quality functional areas specified in GB3095, i.e. nature reserves, scenic spots and other special meeting plants and all staff before and after sales will participate in the special protected areas. Centralized hazardous waste incineration plants are not allowed to be built in densely populated residential, commercial and cultural areas

4.1.2 various incineration plants are not allowed to be built in the upwind area of the dominant wind direction in the residential area

4.2 requirements for incineration

hazardous wastes other than explosive and radioactive wastes can be incinerated

4.3 incinerator exhaust funnel height

4.3.1 see Table 1 for incinerator exhaust funnel height

------------------------------

that is, the fiber orientation is 0 ° incineration capacity (kg/h) the minimum allowable height of waste type exhaust funnel (m)

--------------------------------------------------
