(1) Select from the treated water quality:
The water quality after different processes is very different, for example, the sand pool is used as the main equipment for water treatment, and the effluent turbidity is high.
(2) Choose from operating expenses:
Most systems will produce labor costs, equipment operation costs and maintenance costs, and the key point to be considered is cost. The traditional system will use a lot of equipment, such as rotary drum microfilter, sand cylinder, protein separator, circulating water pump, ultraviolet sterilizer and other electrical equipment, which has high power cost, labor management cost and equipment maintenance cost. Using Tianhao circulating water system, the cost is only generated on the circulating water pump and ultraviolet sterilizer, and other equipment does not use electricity, which greatly reduces the cost. The equipment runs automatically without operation management, and also reduces the labor cost.
(3) Choose from previous investments:
If the funds are sufficient, we suggest to choose a system that can be used for a long time, so as to avoid the secondary cost to the greatest extent and effectively reduce the overall cost from the perspective of long-term operation. In short, it is to buy cheap equipment in advance. The longer the operation time, the higher the additional cost and the lower the final profit. I bought Tianhao's equipment in the early stage. The longer the operation time, the lower the additional cost and the higher the profit.
(4) Selecting from breeding varieties:
At present, the cultured varieties are roughly divided into two categories: one is fresh water and the other is seawater. Iron equipment is definitely not suitable for corrosive seawater. Therefore, it is the most critical to choose the main equipment that can meet the demand of both fresh water and seawater, so pay attention to it when choosing equipment.
(5) Choose from the situation of increasing production and income:
With good water, natural fish and shrimp diseases will be effectively reduced. In the past, the water quality treated by circulating water system was generally the same, so chemicals were constantly added in aquaculture. Once a major disease disaster occurs, it cannot be effectively resisted by adding drugs alone. The most important thing is water quality. Therefore, good equipment is the most important in the selection.
1, circular agriculture
Circular agriculture refers to the activity of promoting various agricultural resources to flow repeatedly and efficiently in the farming system, so as to achieve the purpose of energy saving, emission reduction and income increase, and promote the sustainable development of modern agriculture and rural areas.
Generally speaking, circular agriculture is an agricultural production mode that uses the principle of material recycling and multi-level utilization technology to achieve less waste and improve resource utilization efficiency. As an environment-friendly farming method, circular agriculture has good social, economic and ecological benefits. Only by continuously investing in technology, information and capital to make it a dynamic systematic project can we better promote the recycling of rural resources and the sustainable development of modern agriculture!
2. Development significance
Developing circular agriculture is an important way to implement the strategy of agricultural sustainable development. Circular agriculture is to protect agricultural students by applying the idea of sustainable development, circular economy theory and ecological engineering [1]? On the basis of the environment, make full use of high technology, adjust and optimize the internal structure and industrial structure of agricultural ecosystem, improve the multi-level circulation of material and energy in agricultural system, strictly control the input of foreign harmful substances and the generation of agricultural waste, minimize environmental pollution, make agricultural production and economic activities truly integrate into the agricultural ecosystem circulation, and realize the virtuous cycle of ecology and the sustainable development of agriculture.
3. Characteristics
(1) reduction
Minimize the quality of materials entering the production and consumption process, save resources and reduce pollutant emissions;
(2) Reuse
Improve the utilization efficiency of products and services and reduce the pollution of primary products; [ 1]
(3) recycling
After completing the use function, the article can become a renewable resource again.
The application of modern advanced comprehensive processing and utilization technology and equipment of crops, relying on the advantages of developed planting industry and abundant crop straw resources, will provide high-quality and low-cost crop products with high commercialization for the market, promote the high-quality and efficient development of aquaculture, improve the utilization rate and economic benefits of crop straw, and form an organic industrial cycle of straw feed processing, aquaculture, bio-organic fertilizer and planting. Establish an intensive modern agricultural economic circulation system for efficient utilization of agricultural resources, comprehensively improve the utilization efficiency of agricultural resources and the economic benefits of agricultural production, realize agricultural efficiency, increase farmers' income and rural prosperity, and promote and accelerate the ecological creation project and the construction of ecological villages.
