The solution of sewage treatment technology.

With regard to the wastewater engineering design of leather industrial park, it is suggested that the diversion biological aerated filter (CCB) can complete the process of aeration → sedimentation → secondary aeration → secondary sedimentation in the same treatment tank, thus solving the technological process that other wastewater 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, it was confirmed by 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 that the diversion biological aerated filter was a national key new product with the number of 20 10GR4670 1.

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.

There are many manufacturers who design CCB, and I have also visited many CCB sewage treatment projects. However, Guizhou Great Wall Environmental Protection and Chongqing Chutian Environmental Protection are more professional. They can design, finance construction and pay standards for free. They can compare the scheme with preliminary design, structural design calculation, structural design calculation, general layout and design of sewage plant. The layout and design of sewage flow in the height system need at least plan A0, elevation and structural design.
