Its core part is to directly add the suspended filler whose specific gravity is close to water as the active carrier of microorganisms into the aeration tank, and make it in a fluidized state through the aeration in the aeration tank and the lifting effect of water flow. It is a combination of suspended activated sludge process and attached biofilm process.
1, Sichuan Lianyi Environmental Protection Technology Co., Ltd.-is a scientific and technological enterprise specializing in the design, manufacture and technical installation of R&D, wastewater and sewage treatment equipment led by a professor-level senior engineer. Since its establishment, Ripple has been strictly located in the field of wastewater and sewage treatment, and resolutely refused to diversify. When other companies do two or even three things at the same time, ripple only does this thing.
2. The sewage treatment plant of Puning Textile Printing and Dyeing Environmental Protection Comprehensive Treatment Center is the project with the strictest effluent standard, the smallest treatment area per ton, the most perfect wastewater classification and water quality collection method, the most difficult design and construction and the most complicated geological conditions among similar sewage treatment plants in China. The total investment of this factory is 394 million yuan. Through the classified sewage collection system of "one factory, one type, one pipe and one supervision", the factory adopts pretreatment, biochemical treatment, advanced oxidation and advanced treatment processes to treat the production and domestic wastewater of 66 textile printing and dyeing enterprises in the park, and the sewage treatment scale is 60,000 tons/day.
3. The power supply of Hubei Licheng sewage treatment vehicle has dual functions, that is, if there is no external power supply, it can be operated by the host computer that comes with the vehicle; If there is an external three-phase power supply, you can use the configured wires to connect the motor to run.
As long as there is power supply, it is best to use an external power supply and run with a motor, because electricity is definitely cheaper than diesel engines, and the wear and tear of motors is far less than that of diesel engines, which can save most of the funds for customer groups, which is also a major advantage of sewage treatment vehicles.
Tianjin Jiayi Sheng Da Automobile Co., Ltd. is a production enterprise integrating R&D, sewage sludge treatment vehicle manufacturing and sales. The company is located in Jixian Industrial Park, Tianjin, with a registered capital of 22 million yuan, total assets of 200 million yuan and an area of 60,000 square meters, including a building area of 25,000 square meters, 35 senior and intermediate technicians, and employees with college education or above account for 50% of the total number of enterprises.
5. Qilidian Sewage Treatment Process (I) Sewage Treatment and Its Process Brief Introduction Modern sewage treatment technology can be divided into primary, secondary and tertiary treatment according to the treatment degree. Primary treatment mainly removes suspended solid pollutants from sewage.
The extended data "Integrated Sewage Treatment Equipment" adopts a biological contact oxidation tank in the AO biological treatment process, and its packing volume load is relatively low, and microorganisms are in the self-oxidation stage, so the sludge output is less.
In addition, the moisture content of sludge produced by biological contact oxidation tank is much lower than that produced by activated sludge tank. Therefore, the sludge produced by the "integrated sewage treatment equipment" is very small, and generally only needs to be discharged once every 90 days.
The invention is suitable for the treatment and reuse of domestic sewage in residential quarters, villages, towns, office buildings, shopping malls, hotels, restaurants, sanatoriums, institutions, schools, military units, hospitals, highways, railways, factories, mines and tourist attractions, and also suitable for the treatment and reuse of organic wastewater from slaughter, aquatic product processing, food and other similar small and medium-sized industries. The quality of sewage treated by this equipment reaches the first-class B standard of the national comprehensive discharge standard for sewage treatment.
