Modern wastewater treatment technology, categorized by treatment levels, includes primary, secondary, and tertiary treatment. Nanjing Bilan generally determines the treatment level based on the water quality and the intended use of the treated water. Primary treatment mainly removes suspended solid pollutants from wastewater, with physical treatment methods typically only capable of achieving primary treatment standards. After primary treatment, BOD is generally reduced by about 30%, which does not meet discharge standards. Primary treatment is a pre-treatment step for secondary treatment. Secondary treatment primarily removes colloidal and dissolved organic pollutants (BOD, COD substances) from wastewater, achieving a removal rate of over 90%, making organic pollutants meet discharge standards and achieving a 95% removal rate of suspended solids for good effluent quality. Tertiary treatment further processes difficultly biodegradable organic matter, nitrogen, and phosphorus, as well as soluble inorganic substances that can lead to eutrophication in water bodies. Key methods include biological nitrogen and phosphorus removal, coagulation and sedimentation, sand filtration, activated carbon adsorption, Bilan WS Cleaner, ion exchange, and electro dialysis, etc.

Water resources are under threat. It is estimated that by the beginning of the next century, a quarter of the world will face chronic water shortages. Remember, we cannot create water; we can only strive to protect it. The millions of compounds from chemical pollution industries exist in air, soil, water, plants, animals, and human bodies. Even the ice caps, as large natural ecosystems on Earth, are polluted. Those organic compounds, those heavy metals, those toxic products, all concentrate throughout the entire food chain, ultimately threatening the health of plants and animals, causing, and leading to soil fertility decline.

Air pollution is prevalent in most large cities, with the air containing numerous pollutants from heating, transportation, and factory production. These pollutants threaten the health of tens of millions of citizens, leading to many deaths. Toxic gases primarily include carbon monoxide, nitrogen dioxide, and inhalable particles. Despite the signing of the Montreal Protocol, polar ozone layer holes still form above the Earth's poles each spring. The ozone layer in the Arctic has lost 20% to 30%, and in the Antarctic, over 51%. Suzhou Biliang Intelligent Environmental Technology Co., Ltd.
