Diversion biological aerated filter (CCB) makes sewage complete the process of aeration → sedimentation → secondary aeration → secondary sedimentation in the same treatment tank, which solves the technological process that other sewage treatment needs four tanks. Especially in the case of continuous water inflow, intermittent aeration of water inflow → aeration → sedimentation → effluent is realized, and sludge backflow is realized at the same time, and the whole operation is not idling. Its advantages are more prominent than other sewage treatment methods, and the treatment effect is particularly remarkable. CCB sewage treatment equipment is an updated product of sewage treatment equipment such as AB method, SBR method, A2O method, contact oxidation method, secondary aeration and intermittent aeration. In June 2009, it was listed as an "innovative project" by the Ministry of Science and Technology with the project code of 09C26215205564; . In June 5438+February, 2009, the Ministry of Environmental Protection listed this product in the Catalogue of Environmental Protection Technologies Encouraged by the State (UNCED 2009/2009) 2009 146); 20 10 in may, the Ministry of science and technology, the Ministry of environmental protection, the Ministry of commerce and the general administration of quality supervision, inspection and quarantine identified the diversion biological aerated filter as a national key new product with the number of 20 10GR4670 10.
CODcr has been applied in Beijing, Shandong, Hebei, Guizhou, Shanxi, Sichuan, Inner Mongolia, Heilongjiang, Guangdong, Guangxi, Shaanxi, Gansu, Ningxia, Xinjiang, Jiangsu, Jilin, Henan, Hubei and Tianjin in China. The case was established and a lot of wastewater treatment was carried out, such as family, hospital, chemical industry, slaughter, food, flax, alcohol and pharmacy. Generally, BOD5 is below 10 mg/L, and the lowest is 3.50mg/L.: SS is generally below 20 mg/l, and the lowest is 6.55 mg/l.
CCB sewage treatment equipment fully draws lessons from SBR method, AO method, A2O method, oxidation ditch method, activated sludge method, biofilter, biological turntable, biological contact oxidation, anaerobic digestion, hydrolytic acidification, UASB and other anaerobic biological treatment methods and the design technology of secondary or tertiary sewage treatment process, and develops innovative technologies for advanced sewage treatment. In 2005, China National Intellectual Property Administration was approved as a national patent product with patent number ZL200420033672.4.
Photocatalyst sewage purification equipment Photocatalyst sewage purification equipment uses silent discharge technology to generate a large amount of active oxygen and free oxygen O according to photochemical and silent discharge principles. ，O？ React with water to form? Oh, at the same time, it also produces other excited substances and free radicals, which accelerates the chain reaction, and the reaction rate is five times higher than that of ozone. It can effectively remove BOD5, CODcr, SS and other physical and chemical indicators in sewage, and can also kill various bacteria and viruses in sewage. The effect after treatment is better than the national standard, and the reclaimed water can be reused.
According to the principle of high-frequency sonochemistry and silent discharge, "wave catalyst sewage purification equipment" promotes the full dispersion and dissolution of active oxygen, greatly reduces the dosage of active oxygen, and improves its oxidation ability at the same time, thus strengthening the decomposition of active oxygen through physical and chemical action and generating a large number of free radicals; The pollutants in wastewater can also be directly decomposed under the cavitation of high temperature and high pressure, so the enhancement of oxidation capacity of wave catalyst purification equipment is not only a simple addition of high frequency sonochemical method and silent discharge method, but a qualitative leap. It can effectively remove BOD5, CODcr, SS and other physical and chemical indicators in sewage, and can also kill various bacteria and viruses in sewage. The effect after treatment is better than the national standard, and the reclaimed water can be reused. Wave catalyst sewage purification equipment.
"Double-catalyst wastewater purification equipment" fully draws lessons from the design methods of photochemical method, high-frequency sonochemistry method and silent discharge method, so that active oxygen loses an electron, produces extremely high oxidation potential, and has a fast chain reaction with organic pollutants, so that harmful substances in wastewater can be oxidized into CO2, H2O or mineral salts indiscriminately, and can effectively decolorize, denitrify and remove phosphorus, and its oxidation ability is ten times that of ozone. The new sewage treatment project adopts this equipment. The floor space, one-time investment and operation cost are greatly saved. The old sewage treatment project can complete the sewage treatment upgrade without reforming the civil engineering, and it is the most ideal sewage purification equipment at present.
