Description
Technical Field
The invention belongs to the technical field of cultivation, particularly relates to a circulating ecological cultivation system and a buoyancy tank, and particularly relates to a buoyancy tank made of cloth and a system matched with the buoyancy tank.
Background
China is the first aquaculture country in the world, both in terms of aquaculture yield and in terms of aquaculture scale. However, aquaculture operators in China mostly aim at pursuing yield and short-term economic benefits, the aquaculture density is too high, the environmental protection consciousness is weak, and aquaculture diseases are aggravated year by year. Meanwhile, most of the breeding houses in China are cultivated in still water, and a large amount of organic matters such as fish and shrimp excrement, residual bait and the like are deposited on the bottom of water due to high-density cultivation. In the season of vigorous culture, the heterotrophic microorganisms are propagated in large quantity due to high temperature, organic matters are decomposed, and a large amount of harmful substances such as ammonia, nitrite and the like are released, so that the growth and development of fishes and shrimps are influenced, and diseases of the fishes and shrimps are caused.
Physical and chemical methods for purifying aquaculture water have various disadvantages, and microbial communities in natural water are not enough to decompose organic loads in an aquaculture pond, so that a new environment-friendly aquaculture water environment purification method needs to be found.
In recent years, bioremediation techniques in the field of environmental engineering have been applied to pollution control in aquaculture waters, including the removal of excess N, P-containing organic baits from water by using fungi and algae. Among them, the study of fungi has been mostly focused on domestication, immobilization and application of beneficial microorganisms, particularly PSB. For example, in Chinese patent CN1461734 method for restoring aquaculture environment by using microcapsule probiotic water-purifying compound bacteria, photosynthetic bacteria, bacillus and other strains are cultured by a combined fermentation process, freeze-dried, treated by microcapsules and then put into water or added into feed, so as to restore the water; CN1340613 immobilization method of bioremediation-effect bacteria for aquaculture environment provides a technology of taking zeolite as an immobilization carrier, mixing the effect bacteria and the zeolite into a solid product, and putting the solid product into an aquaculture pond, thereby remedying the aquaculture environment; CN 1245151A microorganism treatment system for improving water quality of aquaculture pond comprises enrichment culture method of photosynthetic bacteria and aerobic bacteria, domestication culture method of mixed bacteria hanging membrane, selection of filler and arrangement of biological filter tower. In the aspect of phytoremediation, the aquatic plants are mainly used for inhibiting the release of N, P in the sediment, absorbing excessive nutrient substances and influencing the growth of planktonic algae through resource competition. However, microbial purification is more commonly used in the prior aquaculture water body, and the application of the method to aquatic plant purification is not much.
The method is limited by biological characteristics, and the currently common aquaculture water biological purification method has many limitations, namely firstly, microorganisms which are main groups of biological purification cannot degrade all pollutants in the water, and the insolubility and the biodegradability of the pollutants influence the biological purification effect; secondly, when the concentration of the pollutants in the water body is too low to meet the requirement of microbial degradation, the microbial purification can not exert the normal efficiency; thirdly, the plant biomass for water body restoration is too small to meet the water body purification requirement of large-area pollution. For the culture water body with serious pollution or combined pollution, the ideal effect is often difficult to achieve by a single bioremediation technology. Different bioremediation technologies are effectively combined to form a combined bioremediation technology, so that the aims of degrading and removing pollutants can be more effectively achieved.
In a word, the aquaculture water body is rich in N, P, and also contains excessive bait, prawn excrement, algae, aquatic plants and other biological remains, so that the existing single means or products such as microbial flocculants, enzyme preparations, microbial water quality modifiers, biological floating beds and the like cannot meet the requirement of aquaculture water body purification.
