Industrial wastewater sewage testing including production wastewater and production sewage. According to the products of industrial enterprises and processing objects can be divided into paper wastewater, etching wastewater, textile wastewater, tannery wastewater, pesticide wastewater, metallurgical wastewater, printing and dyeing wastewater, oil refining wastewater, medical wastewater and so on.
Water samples collected before the preparation of sampling
(1) the preparation of the sampler: choose the appropriate sampler, rinse clean (three wash).
(2) container preparation container selection principles: water samples do not dissolve in the container, the container material does not adsorb some components of the water samples, water samples and containers do not have a direct chemical reaction, to avoid the "similarity" principle.
Test items
Life wastewater test items: PH, color, turbidity, odor and taste, visible matter, total hardness, total iron, total manganese, sulfate, chloride, fluoride, cyanide, nitrate, total bacteria, total Escherichia coli, free chlorine, total cadmium, hexavalent chromium, mercury, and total lead.
Industrial wastewater testing items: PH, CODcr, BOD5, petroleum, LAS, ammonia, color, total arsenic, total chromium, hexavalent chromium, copper, nickel, cadmium, zinc, lead, mercury, total phosphorus, chloride, fluoride and so on.
Transportation and preservation of water samples
1, storage of water samples may be adsorbed in containers, tainted water samples, therefore, to choose the performance of stable, low impurity content of the material for the container, commonly used borosilicate glass, quartz, polyethylene, polytetrafluoroethylene, the most commonly used borosilicate glass, polyethylene bottles.
2, water samples should not be lost in the transportation process and loss, to be packaged, labeled, sealed.
3, the transportation process requires as soon as possible, commonly used monitoring vehicles, cars, boats, and even airplanes.

General In order to ensure that the water quality of sewage wastewater treatment to meet the standards, the use of water reuse ultraviolet sterilizer, sewage treatment and disinfection equipment and other facilities to treat the water, which can effectively protect the water quality of sewage wastewater water safety.
