Household Water Purifier is Needed When Confronted with Industrial Wastewater
Industrial wastewater refers to the waste water and waste liquid produced in the industrial production process, including industrial production materials, intermediate products, by-products and pollutants produced in the production process. There are many kinds of industrial waste water with complex composition. For example, the wastewater from electrolytic salt industry contains mercury, the wastewater from heavy metal smelting industry contains various metals such as lead and cadmium, the wastewater from electroplating industry contains various heavy metals such as cyanide and chromium, the wastewater from petroleum refining industry contains phenol, and the wastewater from pesticide manufacturing industry contains various pesticides. Industrial wastewater is an important pollution source of water area, which has the characteristics of large quantity, wide area, complex composition, high toxicity, not easy to purify and difficult to treat. Because industrial wastewater often contains a variety of toxic substances, environmental pollution has a great harm to human health, usually need to take corresponding purification measures for disposal before discharge.
Some industrial accidents will make industrial wastewater flow into the nature, and some factories intentionally discharge untreated wastewater directly into the water, resulting in serious water pollution. After the industrial wastewater is discharged into the river, it flows down the river, and the organisms in the water take in toxic substances and then enter the human body along the food chain; Affecting the soil and water (such as well water) of several kilometers along the river; the toxic substances will also settle at the bottom of the river and stay for a long time. The water shortage and accidents caused by water pollution not only make the factory stop production, agriculture reduce production and even cut off, but also cause bad social impact and great economic loss, which seriously threaten the sustainable development of society and human health.
The household water purifier can be used to filter the floating objects, heavy metals, bacteria, viruses, residual chlorine, sediment, rust, microorganisms, etc. in the water. It has high-precision filtration technology. The first stage of the five-stage filtration technology of household water purifier is PP filter cartridge, the second stage is granular activated carbon filter cartridge, the third stage is precision compressed activated carbon filter cartridge, the fourth stage is reverse osmosis membrane or ultrafiltration membrane, and the fifth stage is post activated carbon (t33). The water purifier is not only suitable for areas with serious water pollution, but also can filter the residual chlorine in the conventional tap water and improve the sense of using water.
In order to ensure people's water safety, it is necessary for the government to improve the drinking water laws and regulations, strengthen the supervision, and implement the policies about industrial wastewater discharge as soon as possible.
