Mixed culture system and method combined with domestic sewage treatment

Abstract

The invention relates to the technical field of culture of animals and plants, in particular to a mixed culture system combined with domestic sewage treatment. The system comprises a sewage treatmentunit, a traditional Chinese medicine planting unit and a lobster breeding unit, wherein the sewage treatment unit comprises a water collecting pool, a filtering pool, an aerobic ecological pool and ananaerobic ecological pool which are communicated in sequence; the traditional Chinese medicine planting unit comprises a Chinese herbal medicine planting bed which is arranged at the top of the anaerobic ecological pool, and the Chinese herbal medicine planting bed and the anaerobic ecological pool are spaced by a hollow-out partition; the lobster breeding unit comprises a lobster culture pool which is connected with a drain port of the anaerobic ecological pool through a water pipe. By means of the mixed culture, the domestic sewage is effectively treated and sufficiently utilized and can promote Chinese herbal medicine planting and lobster breeding, the efficiency of sewage treatment can be improved by Chinese herbal medicine planting and lobster breeding, and good economic benefit is obtained.

Description

technical field [0001] The invention relates to the technical field of animal and plant breeding, in particular to a mixed breeding system and method combined with domestic sewage treatment. Background technique [0002] Farmers' domestic sewage mainly refers to four kinds of sewage, including sanitary water for human feces and urine, washing wastewater, kitchen swill and breeding wastewater. There is no heavy metal pollution in domestic sewage, but it contains a large amount of organic matter, such as cellulose, starch, sugar and fat protein. It also contains chloride, carbonate, bicarbonate, and inorganic substances such as sodium, potassium, calcium, and magnesium, and contains high nitrogen and phosphorus. Under the action of anaerobic bacteria, it is easy to produce odorous substances. Existing farmers produce Domestic sewage is usually directly discharged into ditches and rivers without treatment, which pollutes the river water, makes the river eutrophic, destroys the ...

[0002] Farmers' domestic sewage mainly refers to four kinds of sewage, including sanitary water for human feces and urine, washing wastewater, kitchen swill and breeding wastewater. There is no heavy metal pollution in domestic sewage, but it contains a large amount of organic matter, such as cellulose, starch, sugar and fat protein. It also contains chloride, carbonate, bicarbonate, and inorganic substances such as sodium, potassium, calcium, and magnesium, and contains high nitrogen and phosphorus. Under the action of anaerobic bacteria, it is easy to produce odorous substances. Existing farmers produce The domestic sewage is usually directly discharged into ditches and rivers without treatment, which pollutes the river water, makes the river eutrophic, destroys the ecological balance of the water body, produces a lot of stench, and affects people's living environment

With the continuous improvement of people's living standards and the gradual improvement of environmental protection awareness, some rural areas will treat the domestic sewage of farmers and then discharge it. In addition, most of the existing sewage treatment systems only start from solving the sewage problem, without digging and utilizing the value of domestic sewage itself on the basis of solving the sewage problem, so they cannot give full play to the life. The resource type and value of sewage, because farmers cannot obtain corresponding benefits in the process of sewage treatment, so the long-term large-scale promotion and use of traditional sewage treatment systems for farmers cannot be effectively implemented

[0003] Because the planting of Chinese herbal medicine has good economic value and can bring good economic benefits to farmers, existing farmers use a large amount of farmyard manure and chemical fertilizers in the process of planting Chinese herbal medicine in order to promote the growth of Chinese herbal medicine and increase their income, which increases the cost of planting , reducing the quality of Chinese herbal medicines but the effect is not obvious, and lobster farming has been sought after by farmers this year. Lobsters are omnivorous animals with strong adaptability, high fecundity, fast growth, high temperature resistance, low oxygen resistance, and meat quality. It is tender, delicious, and nutritious, but there are high cost of breeding in the breeding process, the market value of ordinary finished products is not high, and there is a phenomenon of high mortality in the breeding process
