Description
Technical field
The present invention relates to a kind of the waste seawater that produces in the Macrobrachium rosenbergii breeding process be carried out the regenerated method; specifically, belong to energy-saving and emission-reduction and protection ecotechnology field, waters with a kind of artificial water purification technology of waste seawater that discharges in the Macrobrachium rosenbergii breeding process through being used further to after the purifying treatment grow seedlings and produce.
Background technology
Macrobrachium rosenbergii Macrobrachium rosonbergii (de Man) has formed one of kind that mass-producing and industrialization produce in the shrimps kind introduced of China.In recent years, along with cultured area enlarges, the turnout of shrimp seedling also improves thereupon, grows seedlings to produce disabled person worker's seawater quantity of being discharged and also increasing year by year, and the pollution of lake, river course or pond water quality is also being increased the weight of.The common method of handling Macrobrachium rosenbergii breeding waste seawater at present has: 1. adopt biological filter; 2. cultivate algae and zooplankton; 3. adopt ozone+dioxide peroxide (bromochlorohydantoin, C5H6Br2N2O2) sterilization; 4. multi stage precipitation; 5. sand filtration; 6. foam separator; 7. disinfection by ultraviolet light.1. above-mentioned method for purifying water is suitable for using in the water of antibiotic-free, but microbial film is difficult to survive when using in Macrobrachium rosenbergii breeding waste seawater, so effect is relatively poor.2. with the sterilization of slow-release medicines such as dioxide peroxide and C5H6Br2N2O2, oxidation effectiveness is not good, and the drug residue time is long, is unfavorable for recycling.3. above-mentioned water-purifying process need adopt the multi stage precipitation purifying treatment, the repeatedly energy consumption height of water lift, and shortage continuity, and the construction costs height, practical extending application value is low.4. purifying water with biological filter requires the organic content can not be too high, otherwise stops up easily, and common the circulation primary of waste water after therefore handling just must enter water drain, can't continue use, and the pollution problem of environment is still existed.5. adopt the investment of biological filter and foam separator big, floor space is many, and the cost of regeneration seawater is higher than the artificial seawater of new preparation, and the purifying method of therefore existing Macrobrachium rosenbergii breeding waste seawater exists obvious defects and deficiency.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of method of handling Macrobrachium rosenbergii breeding waste seawater is provided, make breeding waste seawater be able to recycle,, reduce production costs, promote the development of Macrobrachium rosenbergii industry with the protection water area ecological environment.
