Abstract
The invention relates to indoor closed type circulating aquaculture seawater treatment, in particular to a method for treating circulating aquaculture seawater with hydroponic spartina alterniflora loisel. The method is characterized by comprising the steps that wild spartina alterniflora loisel is dug, and after mud on a root system of the wild spartina alterniflora loisel is cleaned up, the wild spartina alterniflora loisel is planted on a biologic ball with corallite in a biofilter with the planting distance of 10 cm; when the aquaculture seawater enters the bottom of the biofilter through a water inlet pipe and flows through the biologic ball upwards, organic matter is decomposed into inorganic matter through the microbial action; then when the aquaculture seawater flows through the root system of the spartina alterniflora loisel, inorganic nitrogen and phosphorus nutrient elements in the water are removed out of an aquaculture system through absorption of the root system of the spartina alterniflora loisel, and the aim of purifying water is achieved.
Description
Technical field
The present invention relates to indoor closed cyclic culture brine disposal, especially ammonium nitrogen, nitroso-group nitrogen, nitrate, phosphatic method in biological removal cyclic culture seawater.
Background technology
In indoor closed circulating water culture system, along with the prolongation of culturing time, a large amount of bait is put in cultivating system, through the digestion of ingesting of aquaculture organism, a large amount of movement enters aquaculture water, the objectionable impurities such as ammonium nitrogen, nitroso-group nitrogen, nitrate, phosphoric acid salt of accumulation, had both destroyed water quality, endangered aquaculture organism safety again.The common method removing above-mentioned substance in water mainly contains ion exchange method, membrane separation process, biological respinse method etc.; In indoor freshwater aquiculture, utilize hydrobiontic algae to grow the method absorbing and remove nitrogen phosphorus at present more; But due to weed heatproof, summer easily rot etc. singularity, weed circulating seawer cultivation in application rarely have research.
Spartina alterniflora loisel (SpartinaalternifloraLoisel) is a kind of excellent purification of water quality kind; But because its population propagation rate is too fast, bring certain impact can to local endemic species, cause serious threat to Coastal Ecosystem, be classified as invasive species by country at present.Therefore the research of spartina alterniflora loisel is limited to species diversity aspect more at present, little at comprehensive utilization progress.How spartina alterniflora loisel is fully utilized in indoor closed seawater circulation water cultivating system, give full play to its salt tolerant, high temperature resistant, well developed root system and absorbed nitrogen phosphorus ability strong, grow the characteristics such as fast, the major issue that indoor closed cyclic culture brine disposal faces, urgently to be resolved hurrily.
Summary of the invention
The present invention seeks to solve in prior art and carry out a biological disposal upon that breeding seawater method is less, the problem of less effective, a kind of bioremediation being applicable to indoor circulation breeding seawater is provided.By utilizing the method needing the nutritive substances such as absorbed nitrogen phosphorus in spartina alterniflora loisel's process of growth, the form that the nutritive elements such as the unnecessary nitrogen phosphorus put into Feed forms in cultivating system absorb with spartina alterniflora loisel's plant strain growth is removed from cultivating system.
Technical scheme of the present invention takes wild spartina alterniflora loisel, cleaned up by the earth on its root system with seawater; The biological ball of corallite is housed to 5cm place, underwater lay at the biological filter first half of indoor closed water cycle, cleaned spartina alterniflora loisel is inserted in biological ball and is kept upright, be spaced apart 10cm between every strain spartina alterniflora loisel, spartina alterniflora loisel's blade of plantation need surface completely; When breeding seawater enters bottom water treating pond by water inlet pipe, be inorganics through microbial process by organic substance decomposing when upwards flowing through biological ball, after by the root system of spartina alterniflora loisel, the Nutrient Absorptions such as the inorganic nitrogen phosphorus in water are fallen when flowing through spartina alterniflora loisel, reach the object purified water, the seawater processed flows back to culturing pool through water outlet, completes biological treatment.
Present invention process is simple and clear, easy handling, water treatment effect are excellent, is the plantation of spartina alterniflora loisel's water planting and brine disposal aspect first Application.Our experiments show that and the spartina alterniflora loisel plant of root system weight in wet base 5g is planted in 2mg/L ammonium nitrogen, 2mg/L nitroso-group nitrogen and the phosphatic nutrient solution of 2mg/L respectively, through 12 hr adsorption, it is respectively 46%, 63% and 21%, successful to the average absorption rate of three kinds of nutritive elements.In addition spartina alterniflora loisel's wide material sources, be easy to draw materials, it is a kind of water treatment plants of excellent practicality, its stronger salt tolerance, high temperature resistant, nitrogen phosphorus absorb and energy for growth fast, make the method for water planting spartina alterniflora loisel cycle for the treatment of breeding seawater have great application value in the process of indoor aquatic products breeding seawater.

Embodiment
The specific embodiment of the present invention takes wild spartina alterniflora loisel 4, cleaned up by the earth on its root system 6 with nature seawater; The biological ball 3 of corallite is housed to the water surface 7 times 5cm place laies at biological filter 5 first half of indoor closed water cycle, cleaned spartina alterniflora loisel 4 is inserted in biological ball 3 and is kept upright, be spaced apart 10cm between every strain spartina alterniflora loisel 4, spartina alterniflora loisel 4 blade of plantation need surface completely; When breeding seawater enters bottom biological filter 5 by water inlet pipe 1, upwards by biological ball 3, be inorganics through microbial process by the organic substance decomposing in seawater, after flow through spartina alterniflora loisel's root system 6, absorbed by the root system 6 of spartina alterniflora loisel's prosperity, removed from cultivating system by inorganic nitrogen phosphorus nutrition element in seawater, the seawater processed flows back to culturing pool through water outlet 2, completes biological treatment.2 ~ 3 harvestings are carried out every year depending on spartina alterniflora loisel 4 growth and the dense situation of blade; Spent fringe to cut during spartina alterniflora loisel's 4 season of flowers, stop its seed and flow in external environment with sewer; Withered and yellow spartina alterniflora loisel 4 Leaf Pruning falls by winter, prevent its rot, only stay root wait for the coming year in water germinate use again.
