Choose the factory recycled water aquaculture system can be considered from the following four aspects:
(a) from the treatment of the water quality situation to choose:
different processes to deal with out of the water quality situation varies greatly, for example: the use of sand tanks as the main body of the water treatment equipment, the effluent turbidity & lt; 20um, and the use of the Tianhao integrated equipment, effluent turbidity ≤ 3NTU.
(b) from the operating costs to choose:
most of the system will incur labor costs, and I heard that the future of this kind of factory aquaculture is promising. p>
(B) from the operating costs to choose:
Most of the system will incur labor costs, equipment operating costs, maintenance costs, consider the key point is the amount of money. Traditional system inside will use a large number of equipment, such as rotary drum microfilter, sand tank, protein separator, circulating water pumps, ultraviolet sterilizers and other electrical equipment, power costs, labor management costs, equipment maintenance and repair costs in the later stage is very high; the use of Tianhao circulating water system, the cost is only generated in the circulating water pumps and ultraviolet sterilizers, the other equipment does not use electricity, which greatly reduces the cost of expenditure, and equipment Automated operation, no need to operate and manage, but also reduces the cost of labor expenses.
(C) from the previous investment situation to choose:
If in the case of more sufficient funds, we recommend or to choose the system that can be used for a long time, so as to maximize the avoidance of secondary costs, calculated from the point of view of long-term operation, is able to effectively reduce the overall cost. In short, is to buy cheap equipment in the early stage, the longer the operation time, the higher the additional costs incurred, the lower the final profit will be. The longer the run time, the lower the additional costs incurred and the higher the profit will be when the equipment of Tianhao is purchased in the early stage.
(D) from the situation of breeding varieties to choose:
Now the breeding varieties are roughly divided into two categories: one is freshwater, one is seawater. Iron equipment is certainly not suitable for corrosive seawater use. Therefore, the main equipment that can meet the needs of both freshwater and seawater is the most crucial in the selection.
(E) choose from the situation of increased production and income:
Water is good, natural fish and shrimp diseases will be effectively reduced. Previously circulating water system to deal with the general quality of water, so in the breeding will keep adding agents, etc., once encountered a major disease, just by adding drugs can not be effectively resisted, the most critical is still the quality of water. Therefore, good equipment in the choice of the most important.
1, circular agriculture
Circular agriculture, refers to the farming system to promote a variety of agricultural resources reciprocal multi-layer and efficient flow of activities, as a way to achieve energy saving and emission reduction and income generation, and promote the sustainable development of modern agriculture and rural areas.
In layman's terms, circular agriculture is the use of the principle of material recycling and multi-level utilization of material technology, to achieve the production of less waste and improve the efficiency of resource utilization of agricultural production methods. As an environmentally friendly farming method, circular agriculture has better social, economic and ecological benefits. Only by continuously inputting technology, information and capital to make it a vibrant systematic project can we better promote the recycling of rural resources and the sustainable development of modern agriculture!
2, the significance of the development
Development of circular agriculture is the implementation of the realization of sustainable agricultural development strategy is an important way. Circular agriculture is the use of sustainable development thinking and circular economy theory and ecological engineering methods, in the protection of agricultural life [1]? Ecological environment and make full use of high technology on the basis of adjusting and optimizing the internal structure of the agricultural ecosystem and industrial structure, improve the multi-level recycling of material and energy in the agricultural system, strictly control the input of external hazardous substances and the generation of agricultural wastes, to minimize environmental pollution, so that the agricultural production and economic activities are truly integrated into the agro-ecosystem cycle to achieve the benign cycle of ecology and sustainable development of agriculture. The sustainable development of agriculture.
3. Characteristics
(1) Reduction
Minimize the amount of material entering the production and consumption process, save the use of resources, and reduce the emission of pollutants;
(2) Reuse
Improve the efficiency of the use of products and services, and reduce the pollution of disposable products;[1]
(3) Recycle
After the completion of the use function of the object, it can be reused. Objects are able to be turned back into renewable resources after completing their use function.
Applying modern advanced comprehensive crop processing and utilization technology and equipment, relying on the advantages of developed planting industry and abundant crop straw resources, providing the market with high-quality and low-priced crop products with high degree of commercialization, promoting high-quality and efficient development of aquaculture, improving the utilization rate of crop straw and economic benefits, and enabling the formation of an organic industrial cycle between the straw feed processing, aquaculture, bio-organic fertilizers, and planting industry. Organic industrial cycle, the establishment of efficient use of agricultural resources, intensive modern agricultural economic cycle system, comprehensively improve the efficiency of agricultural resource utilization and economic benefits of agricultural production, to achieve agricultural efficiency, farmers income, rural prosperity, to promote and accelerate the creation of ecological engineering construction and ecological village construction.
