Description
Technical field
The present invention relates to the recycle of aquiculture sewerage and the second use facility of solid particulate matter.
Background technology
Generally speaking, the protein transduction of the 20-25% of the bait of throwing something and feeding in the intensive aquaculture activity changes the flesh of fish into, and remaining form with ammonia nitrogen, residual bait and ight soil is present in the breeding environment.Having the residual bait and the ight soil of breeding water body is the main source of ammonia nitrogen in the water body, nitrous acid nitrogen etc., and the degraded of solid particulate matter can consume a large amount of oxygen.So, require when designing to shift out system to particle efficiently in the short as far as possible time in system for circulating water culture system.
For the ammonia nitrogen in the water body and residual bait and ight soil, a kind of processing method is to change water.It is estimated that the prawn of culturing 1kg will consume 20m
3The cleaning water source, the cleaning water source of culturing the consumption of 1kg fish is approximately 2-10m
3Second method is breeding water to be handled again utilize, i.e. circulating water cultivation, and general circulating water cultivation water body recycling rate of waterused is 95%, the water resource of every 1kg cultured output consumption is approximately 20-30l.The cost of water treatment of circulating water cultivation is the key factor of decision culture benefit.Circulating water cultivation water treatment facilities commonly used at present comprises biofilter, foam separator, solid-liquid separating machine etc.Can produce a large amount of solid waste in the circulating water culture system, research shows, produces the circulating water cultivation field of 1000kg per year, the annual solid particle discarded object that produces 375kg.
The solid particulate matter that the freshwater aquiculture system produces can be used for compost and irrigation.Then resource is relatively more difficult because contain salt for the solid particulate matter that produces in the mariculture system.So how to realize that the resource of solid particulate matter in the aquaculture system and minimizing are the core technologies that realizes circulating water culture system zero disposal of pollutants, the processing method of having reported commonly used is to carry out anaerobic digestion.Facts have proved this processing method reaction time oversize (1-2 month), and the reactor floor space is bigger.
The inorganic nitrogen assimilation process of bioflocculation techniques make use microorganism changes into bacterial components with ammonia nitrogen, nitrous acid nitrogen and nitrate, is comparatively one of mature technique of using in the Wastewater Treated by Activated Sludge Process municipal wastewater.Bioflocculation can be realized the quick conversion of ammonia in the water body.If the carbon of solubilised state, nitrogen are than the balance of keeping certain level (C/N＞15) in the water body, the biomass that the ammonia nitrogen in the water body can directly change into heterotrophic bacteria through the mode of bioflocculation is removed.Because the growth metabolism speed of heterotrophic bacteria about 10 times to the autotrophic bacteria of nitrifying bacteria class, transform so the heterotrophism ammonia of realizing through bioflocculation transforms the ammonia of obviously realizing faster than nitrification.Bioflocculation can be realized the second use of residual bait and ight soil in the breeding water body.Bacterium and epiphytic algae form the particle swarm aggressiveness attached to deriving from the ight soil that produces in residual bait of fish and the ight soil decomposable process.Bacterium and algae are because the relation of size and existence differs and directly absorbed by fish surely.If particle swarm aggressiveness form, just can be by filter-feeding, ominivore-fish and shrimp picked-up.Result of the test shows that growth rate is good behind the bacterium floccule bodys of ingesting such as silver carp, Tilapia mossambica, shrimp, and assimilability is also high.The bioflocculation technology is to reduce the cost of water treatment for the meaning of aquaculture, and realizes the second use of refuse, reduces feed cost.
The applying biological flocculation technique is an in-situ treatment in the aquaculture commonly used, promptly directly in shrimp-cultivation pool and Tilapia mossambica breed pond, adds carbon source, inflation, creates the environmental condition that is suitable for forming floccule body, realizes the recycling of purification of water quality and residual bait and ight soil.The advantage of this mode is that cost is low.But there is drawback: 1, cause anoxic microbial degradation organic matter meeting consume oxygen easily, in breeding water body, directly add carbon source and can cause the unexpected consumption of oxygen in the water body and influence the growth of culturing object; The too high bioflocculation that directly in breeding water body, forms of 2 turbidities is known from experience the suspended particulate matter concentration increase that makes in the breeding water body and is influenced the growth of culturing object.
