Aquaculture raw water and circulating water treatment equipment sales and engineering

MBFB technique used in aquaculture raw water system, raw water pesticide, herbicide, disinfectant and other small organic molecules under conditions of aeration and activated charcoal powder in a fluidized state mass transfer, mixed, adsorbed, enriched In the surface of activated carbon, activated carbon surface to form a local pollutant concentration zone; powdered activated carbon for microbial growth and also provides special surface, porous surface adsorption of a large number of microbial flora under high oxygen conditions, microbial enrichment carbon surface locally concentrated pesticides, herbicides, disinfectant and other small molecule oxidative decomposition of organic matter, and then use split water and membrane separation system powdered activated carbon adsorption of organic matter, such as suspended particles separated by cross-flow filtration system to take free Containing less pesticides, herbicides, disinfectant and other small organic molecules of the raw water. The best way to achieve aquaculture recirculating aquaculture, traditional water sources depend on farming model is very serious, once water pollution, aquaculture is facing a huge risk. Recirculating aquaculture achieve its core technology change this situation is MBFB processes. MBFB membrane biological fluidized bed biological fluidized bed based, powdered activated carbon and other media as the carrier, combined with inorganic ceramic membrane solid-liquid separation technology, is the conventional activated sludge process and biofilm Combination of wastewater treatment technologies. Physical adsorption of biological fluidized bed reactor set the carrier, microbial degradation and membrane separation efficiency as a whole, so that the next carrier organics and mass transfer sufficient aeration, mixing, carrier of organic matter, microbes and dissolved oxygen adsorption, rich collection, hydrolysis, oxidation and decomposition, and finally use a ceramic membrane separation system water and adsorbed organic compounds, such as suspended particles separate carrier, through cross-flow filtration, and further purify sewage to reach the water reuse standards, studies show, MBFB effective removal of micro-polluted water ammonia, COD and other small molecules toxic biodegradable organic matter. Circulating water treatment processes: Mariculture circulating water using flotation -MBFB- AFF- entraining UV disinfection process, which filter the raw water directly AFF greater than 5 microns in diameter suspended solids; MBFB is an efficient bioreactor, biochemical processing efficiency is 20 times the normal biological filtration, water can effectively remove organic matter and ammonia, nitrite and other toxic compounds; ultraviolet disinfection or sterilization mainly photocatalytic disinfection process, high disinfection efficiency, no drug residue. Freshwater and marine aquaculture circulating water treatment process is similar, but there is no flotation section.
