Bolt: Machine part, cylindrical threaded fastener with nut. A type of fastener consisting of a head and a screw (cylindrical body with external thread) to be fitted with a nut for fastening two parts with through holes.

This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection belongs to the detachable connection.

According to the report, during last year’s environmental review, environmental protection teams handled nearly 40,000 cases, ordered more than 12,000 enterprises to rectify, filed cases and punished nearly 3,000 enterprises, and fined more than 20 million yuan. Mr. Li mentioned at the meeting that seven environmental protection tasks must be strictly inspected in 2019.

1,Special personnel must go to the site to conduct close inspection of ecological and environmental protection.

Problems found should be sorted out and put on record. Interview with relevant person in charge as appropriate.

2,Inspection of underground sewage. For our bolt production industry, it does produce a certain amount of sewage, which needs to be treated by a professional sewage pool for deposit and precipitation. This link is unavoidable for bolt enterprises, and we must pay attention to it.

3, sewage treatment. That is, we talked about above, professional storage and sewage sedimentation process input.

3,Voice pollution. This is the bolt enterprise, basically no problem. The production of the bolts itself does not create a lot of noise pollution, and the production units are located in industrial areas, which does not disturb schools or residents.

4,Waste gas pollution. This link seems to have no impact on bolt production units, which is mainly about the chemical industry more.

5,But the galvanized factory supporting the bolts is very relevant, if the galvanized factory is closed, it will indirectly affect the bolt enterprises.

6,Preplan for environmental risks and related emergencies. This project is every enterprise needs to pay attention to, it not only involves the problem of environmental pollution, but also involves the problem of safe operation.

7, solid waste treatment. For bolt enterprises, the correlation is not large. The production of bolts is basically the feeding and forming of wire rods, which will not produce excess waste.

When the environmental protection mechanism takes shape, the bolt manufacturers in the same area, some of them meet the standards, some of them do not meet the standards, but in the review, they will all shut down, which is not fair for the bolt enterprises that meet the standards.

So the main topic of this year is to oppose this kind of one-size-fits-all phenomenon. Our bolt manufacturers should also respect the market, respect the law, environmental protection is everyone’s responsibility.
