HJ 865-2017Technical specification for olfactory laboratory construction (English PDF)

Foreword

In order to carry out "Law of the People's Republic of China on Environmental Protection" and "Law of the People's Republic of China on Prevention and Control of Atmospheric Pollution", prevent and control foul-smelling pollution and improve Environmental quality, standardize the construction of foul odor laboratory, the development of this standard.

This standard specifies the stench olfactory laboratory location, layout and internal design and other technical requirements.

This standard is released for the first time.

This standard by the Environmental Protection Department of Atmospheric Environment Management Division, Science and Technology Standards Division organization.

This standard is mainly drafted by. Tianjin Institute of Environmental Protection, Binhai New Area, Tianjin, Hangu Environmental Protection Monitoring Station.

This standard MEP approved on November 10, 2017.

This standard since November 10, 2017 onwards.

This standard is interpreted by the MEP.

Odor and smell laboratory construction technical specifications

1 Scope of application

This standard specifies the stench olfactory laboratory location, layout and internal design and other technical requirements.

This standard applies to the construction of foul smell laboratory.

2 Normative references

This standard references the following documents in the terms. For undated references, the effective version applies this standard.

GB/T 14675 air quality malodor three points comparison Odor bag method Architectural Design Code of Science Laboratory

3 Terms and definitions

The following terms and definitions apply to this standard.

4 New laboratory site

4.1 foul smell Laboratory should be far away from odor sources and noise sources, as adjacent to other laboratories, should be effectively isolated, and set Set independent access.

4.2 foul smell When the site is located in the laboratory, it is necessary to measure the odor concentration of the air outside the foul smell building laboratory, the maximum concentration should be less than 10.

5 Laboratory layout

5.1 Stench Olfactory Laboratory shall have a sampling preparation room, sample preparation room, three functional areas sniffing chamber, equipped with olfactory instrument Laboratory to be set olfactory pump room. Conditional laboratory can be additional lounge. The layout of the functional areas should be concentrated and compact Clear, easy to contact, do not interfere with each other. The foul odor laboratory layout can refer to Figure 1.

5.2 Stench Olfactory Laboratory's functional area and main functions. Sampling preparation room for the storage of sampling equipment, sampler prior to use Preparation, after the determination of the sample processing, sampling equipment cleaning; sample preparation room for the determination of equipment storage, sample short-term deposit Release, odorless air preparation, sample preparation, etc .; sniffing chamber for sniffing samples sniffing identification; lounge for sniffers to provide air Clean rest environment, alleviating the sense of smell fatigue.

5.3 Sample preparation rooms can be shared with other laboratories, but need to meet the laboratory's internal design (6) requirements. Sample with Room should be adjacent to the sniffing chamber, and set the transfer window. Transmission window length of not less than 0.60 m, a height of not less than 0.40 m, refer to Figure 2 design.

6 Laboratory interior design

7 Safety and protection

7.1 Vials and other fragile experimental equipment storage should be set "fragile" safety signs.

7.2 Sampler storage area should distinguish between clean area and work area, and set the safety mark.

7.3 Waste sample handling must be done in a fume hood.

7.4 Other requirements refer to JGJ 91 implementation.
