AudLong Water Treatment's method of treating impurities in water is to include impurities in the water, including coarse substances, suspended matter, colloids and dissolved matter. Coarse materials such as floating aquatic weeds in the river, garbage, large aquatic organisms, grit in waste water, and large pieces of dirt. In water supply projects, coarse impurities are removed by facilities for taking water structures and are not included in the scope of water treatment. In the circulating water system and water regeneration treatment, the raw water is wastewater and the finished water is water. The processing process has both the characteristics of water supply and wastewater treatment.
Water treatment also includes the treatment and final disposal of wastewater and sludge generated during the treatment process (see Sludge Treatment and Disposal). AudLong Water Treatment addresses sometimes the treatment and discharge of exhaust gases. In wastewater treatment, removing coarse impurities generally belongs to the pretreatment part of water. Suspensions and colloids include sediment, algae, bacteria, viruses, and insoluble substances that are native to water and produced during water treatment. Dissolved substances include inorganic salts, organic compounds and gases. There are many treatment methods for removing impurities in water, and the scope of application of the main methods can be roughly divided according to the particle size of the impurities. Because the impurities contained in raw water and the allowable impurities in finished water are very different in type and concentration, the water treatment process is also very different.
The AudLong treatment is a secondary treatment for sewage biochemical treatment. The main purpose is to remove non-sinkable suspended matter and soluble biodegradable organic matter. Its process composition is diverse and can be divided into activated sludge method, AB method, A / O Method, A2 / O method, SBR method, oxidation ditch method, stable pond method, land treatment method and other processing methods. Recently, most urban sewage treatment plants have adopted activated sludge method. The principle of biological treatment is to complete the decomposition of organic matter and the synthesis of living organisms through biological action, especially the action of microorganisms, and convert organic pollutants into harmless gas products (CO2), liquid products (water) and organic-rich substances. Solid product (microbial population or biological sludge); excess biological sludge is separated by solid-liquid in the sedimentation tank and removed from the purified sewage.
