Abstract
The invention discloses a residual feed and excreta treatment device for recirculating aquaculture, and relates to the field of bioengineering. In a large-scale high-technology factory-like circulating water aquaculture area, the size of a water body can reach tens of thousands to hundreds of thousands of cubic meters, through a solid-liquid separation process of a water treatment scheme, lots of residual feeds and biological excreta are separated, if the residual feeds and the biological excreta are not treated and are discharged into coastal waters, seawater eutrophication and even red tides can occur, and a pollution consequence is serious. According to the residual feed and excreta treatment device for the recirculating aquaculture, pollution-free comprehensive utilization can be achieved by using a biotechnology, the technological process comprises the steps of acidizing, heating, hydrolyzing, adding chlorella concentrated solutions, conducting anaerobic degradation, filtering a small quantity of residuals, drying to be used as organic fertilizer, replenishing a carbon and nitrogen source by liquid supernatants, heating and disinfecting, conducting aerobic fermentation on a bio-reactor, and obtaining high quality feedstuff mycoprotein and additives. The environmental protection effects of zero emission comprehensive utilization and turning 'waste' into wealth are achieved.
Description
The device that the residual bait of a kind of circulating water cultivation, excreta are handled relates to bioengineering field, in extensive high-tech industrial circulating water cultivating district, can reach the scale of several ten thousand to tens ten thousand stere water bodys, solid-liquid separation process through water treatment process, there are a large amount of residual baits and biological excreta to be separated, as not handled, be discharged into the coastal waters and will generate seawater eutrophication even red tide, pollution effect is serious.
The present invention uses biotechnology that it is carried out nuisanceless comprehensive utilization, its technological process is: concentrate adds hydrochloric acid and is transferred to pH value 4 acidifyings, through pressure cooker at pressure 0.25MP, 120 ℃ of temperature, hydrolysis in 40 minutes, be cooled to 32 ℃, the lonely nitrifying bacteria of inoculation, lactic acid bacteria, EM add chlorella concentrate (promotion growth of microorganism), be sick of and stir fermentation, fully decompose, filter by 400 orders, a small amount of residue oven dry is as fertilizer.
Supernatant replenishes carbon nitrogen source, sterilization is cooled to 32 ℃, inoculation fodder yeast, ocean rhodotorula, the EM flora reaches biological logarithmic phase at the bio-reactor aerobic fermentation, centrifugal extraction, obtain good feed mycoprotein and feed addictive, this device can be realized industrial circulating water cultivating system, to reach zero-emission comprehensive utilization, the environment protecting of turning waste into wealth.
Claims (1)
1. what is claimed is by adding the chlorella concentrate of the device handled of the residual bait of circulating water cultivation, excreta promotes growth of microorganism, adopts anaerobic fermentation and aerobic secondary fermentation technology pattern, trans-utilization rate height.
