Abstract
The invention provides a method for treating livestock and poultry sewage by hydroponic proteinacous, which belongs to the technical field of sewage treatment and comprises the following steps: s1, diluting the livestock and poultry sewage with water, and adjusting the pH value and the conductivity; s2, adding a sterilizing agent and an insecticide into the diluted livestock and poultry sewage; s3, adding a blending liquid with the volume ratio of 1-5% to the livestock and poultry sewage treated in the step S2; according to the mass ratio, the preparation liquid comprises: 5 to 10 percent of biological enzyme, 1 to 3 percent of urease, 5 to 15 percent of mineral substance, 1 to 5 percent of peroxide and the balance of water; s4, transplanting the proteinacous seedlings into the livestock and poultry sewage treated in the step S3 for water culture; s5, harvesting every 20-30 days. The aquatic proteinacous digestion is utilized to treat the livestock and poultry sewage, the treated water is used as the livestock and poultry production water, the proteinacous is recycled to prepare the feed, and the overall treatment cost is low.
Description

Guangxi is a big province of agriculture, is located in the south of China, has a return-to-north line running through the middle, belongs to subtropical climate regions, is along the edges of rivers and coastal regions, and has the advantages of good climate and location for developing planting and breeding cycle industry. With the development of agriculture, the scale of the breeding industry is continuously enlarged, the discharge amount of excrement is greatly increased, and the breeding pollution becomes the largest pollution source of current agricultural production. Nearly 8000 million tons of livestock and poultry feces are produced per year in animal husbandry in all areas, and the quantity of liquid manure exceeds 2 hundred million tons. However, at present, the manure is not effectively treated, a considerable part of the manure even becomes an important pollution source of the ecological environment, and breeding enterprises bear huge cost and environmental protection pressure.
The treatment of feces is a great problem in livestock and poultry breeding industry, the dry feces treatment mode and the process are relatively mature, the urine partial mode and the process are relatively lagged, the discharge capacity is large, the pollutant content is high, and the resource recycling difficulty is large. The livestock and poultry sewage mainly comprises urine, partial excrement and flushing water, and has the characteristics of large discharge amount, high nitrogen content and organic matter concentration, solid-liquid mixing, large treatment difficulty and the like. The commonly used methods for treating wastewater at present include simple physical treatment, aerobic and anaerobic treatment, combined aerobic and anaerobic treatment, and chemical treatment. However, these processes are generally designed less frequently by farms due to the difficulty of withstanding the high operating costs of wastewater treatment. The method for treating the pig farm wastewater by adopting the biological rationalization treatment method has the characteristics of low operation cost, high efficiency, convenient treatment, greenness and no pollution.
The title is Rumex hanus by. Because the leaves are tender and juice like spinach, and various nutrient elements are contained in the tender leaves, and the main part is the edible leaves, the leaf-eating grass is named, and the most important part of the plants due to the protein content is called as the proteinic grass; in south, it is called "eating leaf vegetables". The protein grass powder has comprehensive nutrition and bright color, and is green, nutritional and healthy without any additive. Can replace 30-60% of grains and be applied to various catering foods. In the application of the livestock and poultry feed, the proteinic grass belongs to the grain-saving type protein feed, and the grass is used for replacing grain, so that 30-50% of concentrate can be replaced, and the breeding cost is reduced; meanwhile, the immunity of the livestock and poultry can be enhanced, and the quality of the livestock and poultry products is improved. The protein feed serving as a new resource and a high-quality protein resource of grains plays an immeasurable role in excavating grain-saving type protein feed.
