The main pollution parameters of industrial wastewater
Commonly used are chemical oxygen demand, suspended solids, air lifting stool pH. Five-day biochemical oxygen demand is also commonly used parameters, but not applicable to certain industrial wastewater. Industrial wastewater chemical oxygen demand and bucket brigade five-day biochemical oxygen demand, there are up to a thousand, ten thousand milligrams / liter. Acid and alkali wastewater pH value is often far from 7. Industrial wastewater containing special pollutants, need to use special pollution parameters, such as phenol. Toxic, harmful metal ions, can be used to determine the toxicity of biological experiments (generally fish experiments), Salmonella typhimurium - particle mutagenicity test (Ames Test) to determine the mutagenicity. The choice of pollution parameters depends on how the wastewater is disposed of, that is, the answer depends on its impact on the environment.
Environmental protection equipment refers to the 1653 mechanical products, structures and systems used to control environmental pollution and improve the quality of the environment, which are manufactured and constructed by the production unit or the construction and installation 4102 unit. It is also believed that environmental protection equipment refers to the treatment of environmental pollution mechanical processing products, such as dust collectors, welding fume purifiers, monomer water treatment equipment, noise controllers and so on. This understanding is not comprehensive. Environmental protection equipment should also include the transmission of pollutant-containing fluid power equipment, such as water pumps, fans, conveyors, etc.; also includes the normal operation of pollution control facilities to ensure that the spinal fracture monitoring and control instrumentation, such as detection instruments, pressure gauges, flow monitoring devices, etc.. Environmental management is already a matter of urgency, we should pay more attention to environmental protection. Environmental issues, both the disposer and the waste producer will have a wildly divisive environmental requirements for the installation of environmental protection equipment, dangerous sinks above a lot of environmental protection equipment business information, you can go to take a look. Environmental protection equipment should include complete sets of equipment: such as air purification machine, sewage treatment equipment, ozone generator, industrial oxygen generator. Can be in the industry or home can be on the environmental management equipment.
Environmental protection equipment includes: filtration and dust removal equipment, sewage treatment equipment, air purification equipment, solid waste treatment equipment, noise prevention and control equipment, environmental monitoring equipment, disinfection and anticorrosive equipment, energy saving and consumption reduction equipment, sanitation and cleaning equipment, environmental protection materials and chemicals, environmental protection instruments and meters.
