Commonly used are chemical oxygen demand, suspended solids, pH value of stool, etc. Five-day BOD is also a common parameter, but it is not suitable for some industrial wastewater. The chemical oxygen demand and five-day biochemical oxygen demand of industrial wastewater are as high as 1000 mg/l and 10000 mg/l respectively ... The pH value of acid-base wastewater is often far from 7. When industrial wastewater contains special pollutants, it is necessary to adopt special pollution parameters, such as phenol. Toxic and harmful metal ions can be determined by biological experiments (generally fish experiments), and their mutagenicity can be determined by Ames test. The choice of pollution parameters depends on the treatment method of wastewater, that is, the answer depends on its impact on the environment.
Environmental protection equipment refers to102 mechanical products, structures and systems manufactured and built by production units or construction and installation units to control environmental pollution and improve environmental quality. Some people think that environmental protection equipment refers to mechanical processing products that control environmental pollution, such as dust collectors, welding fume purifiers, monomer water treatment equipment, noise controllers, etc. This understanding is not comprehensive. Environmental protection equipment should also include power equipment for conveying fluid substances containing pollutants, such as water pumps, fans, conveyors, etc. At the same time, it also includes monitoring and control instruments, such as test instruments, pressure gauges and flow monitoring devices. To ensure the normal operation of spina bifida prevention facilities and prevent pollution. Environmental governance is a top priority, and more attention should be paid to environmental protection. There are many environmental problems. Whether it is the disposer or the waste producer, there will be wild environmental protection requirements to install environmental protection equipment. There is a lot of information about environmental protection equipment enterprises on the dangerous exchange network, so you can go and have a look. Environmental protection equipment should include complete sets of equipment, such as air purifier, sewage treatment equipment, ozone generator, industrial oxygen generator, etc. Equipment that can control industrial and domestic environments.
Environmental protection equipment includes: filtering and dust removal equipment, sewage treatment equipment, air purification equipment, solid waste treatment equipment, noise prevention equipment, environmental monitoring equipment, disinfection and anti-corrosion equipment, energy-saving and consumption-reducing equipment, sanitary cleaning equipment, environmental protection materials and chemicals, and environmental protection instruments and meters.
