Wastewater is mainly divided into industrial wastewater and
domestic wastewater.
Industrial waste water is the waste water produced in industrial
and mining production activities. Industrial wastewater can be
divided into production wastewater and production wastewater.
Production sewage means that it is formed in the process of
production and contaminated by raw materials, semi-finished
products or finished products, and also includes thermal pollution
(refers to the water generated in the process of production and the
temperature of the water exceeds 60℃); Production wastewater refers
to the water formed in the production process, but not directly
involved in the production process, not contaminated by raw
materials, semi-finished products or finished products, or only a
little temperature rise. Production sewage needs to be purified;
Production wastewater does not need to be purified or simply
treated, such as cooling. The mixed sewage of domestic sewage and
production sewage is called municipal sewage.
Waste water testing service items: color, odor and taste, PH, SS,
CODcr, BOD5, ammonia nitrogen, phosphate, animal and vegetable oil,
petroleum, etc
Waste water quality inspection method standard GB 8978-1996.
2. Certification services
The test report issued by Global Zhongyi has legal effect and can be used in scenarios such as the entry of supermarkets, product appeals, anti-malicious rights protection, and auctions (appeals and auctions must meet Party A's testing requirements).
