UASB anaerobic reactor
 
 


UASB is the upflow anaerobic sludge bed reactor, the reactor main body can be divided into two areas: the reaction gas, liquid and solid phase separation areas.Sewage through the pump to the bottom of the anaerobic reactor, using the cloth at the bottom of the water system of sewage evenly arranged on the whole cross section, using the outlet pressure of the water and gas at the same time, make the wastewater with high concentrations of anaerobic sludge fully contact and mass transfer, the organic matter degradation in waste water.Waste water slowly increase the reaction area, further degradation of organic matter.Gas, water and sludge in the process of rising at the same time, the biogas into the three-phase separator internal discharge through the pipe first, sludge and waste water through the cracks of the three-phase separator to separate area, sludge in separation area precipitation enrichment and return to the lower part of the three-phase separator, maintain anaerobic reactor biomass, precipitation of water through the pipe outside the tank.
 
 
At present, shandong gold HaoSanYang environmental protection machinery co., LTD. Of the sewage treatment equipment, sewage treatment technology is widely used in chemical, pesticide, medicine, petrochemical, printing and dyeing, coking, leather, cotton seed processing, food and oil refining chemical industry wastewater treatment project.Of wastewater treatment project in the company to undertake as a benchmark, to strict experimental data for the design of the scientific and standardized, to ensure the success of the one-time drive, treatment effect to national standards or customer name reuse standard.All projects have passed testing and acceptance of environmental protection department, won a good reputation in customers, has set up a file in the environmental protection industry has a certain visibility and reputation.
 


Shandong gold HaoSanYang environmental protection machinery co., LTD., in the chemical industry wastewater treatment has obvious technical advantages, the company invested heavily in recent years for such as: refined cotton, cotton seed protein sewage treatment on wastewater, starch wastewater treatment, paper making black liquor wastewater treatment, pharmaceutical wastewater, leather wastewater treatment, PVC sewage recycling sewage treatment, food, fruit juice wastewater, coking wastewater treatment, power plant recycling sewage reuse, sewage treatment, the study and implementation of various chemical industry wastewater treatment.For many chemical enterprises to solve the problem of sewage disposal, and standard discharge or reuse, is part of the environmental protection department of shandong named shandong sewage treatment industry first peak.Especially in the pharmaceutical intermediates wastewater treatment protein wastewater treatment, refined cotton, cotton, cotton seed protein wastewater treatment, sewage treatment of PVC waste water treatment and paper mill black liquor wastewater and starch wastewater reuse to achieve first-class domestic leading level.
 
 
 
 
 


The development of anaerobic technology
 


Wastewater, especially high concentration organic wastewater anaerobic biological treatment technology, due to the relatively aerobic biological treatment has the incomparable advantage, has been the hot topics in the study of high concentration organic wastewater treatment technology.Anaerobic biological treatment technology of wastewater is a kind of biological treatment technology, to improve the efficiency of anaerobic treatment rate and, in addition to the growth of anaerobic microbe to provide a good environment, high sludge concentration in the reactor and a good mass transfer effect is extremely critical.The development of anaerobic technology has experienced three stages roughly:
 


(1) of the first generation represented by anaerobic touch the anaerobic reactor and sludge retention time (SRT) in equal and hydraulic retention time (HRT), sludge concentration in the reactor is low, treatment effect is poor.In order to achieve better treatment effect, wastewater in the reactor are usually to stay for a few days to a few days.
 


(2) the second generation of the represented by UASB anaerobic reactor, rely on the formation of granular sludge and the role of the three-phase separator, make the sludge in the reactor were stranded, implements the SRT > HRT, to a certain extent to improve the sludge concentration in the reactor, the reactor of the mass transfer process, however, is not ideal.To improve the mass transfer effect, is the most effective ways to improve the surface hydraulic load and surface gas load.However high load produced by vigorous agitation and can make the sludge is in a state of complete expansion in the reactor, sludge excess loss, have to rely on the sludge flooded back to increase biomass, make originally to SRT = HRT, SRT > HRT treatment effect.
 


(3) as a typical representative of the third generation of anaerobic reactors, my company research and development by BIC, on the basis of the second generation of anaerobic reactors is optimized design, absorb its advantage, overcome its shortcomings, formed the leading domestic industry, have their distinct characteristics of anaerobic treatment reactor.BIC has low investment, less land, high load, impact resistance, low operating cost, and stable operation, etc.
