Abstract
The invention provides a composting method for efficient degradation of tetracycline antibiotics in livestock and poultry breeding excrement and belongs to the technical field of environment-friendly livestock breeding. Composting raw materials adopted in the method include, by weight, 30-50% of maize straw, 30-50% of wheat straw, 5-15% of peanut shell and 5-15% of sweet potato stem. According to the composting method, the raw materials are wide in source and low in cost, the composting period is relatively short, and the removal rate of the tetracycline antibiotics is very high.
Description
Technical field
The present invention relates to herding environment-protecting cultivation technical field, specifically, is the compost method about tetracycline antibiotics in a kind of efficient degradation livestock and poultry cultivation ight soil.
Background technology
Along with the fast development of the intensive livestock and poultry breeding industry of China and the continuous expansion of management mode, livestock breeding wastewater pollution problem is increasingly outstanding.The nitrogen contained in livestock breeding wastewater, phosphorus, microbiotic (as sulfamido, Macrolide and tetracyclines) are low with heavy metal (copper, arsenic, zinc, lead and nickel etc.) isoconcentration is but the high pollutent endangered, and constitutes huge potential threat to human health.The portion report of America NI H is pointed out, in livestock and poultry breeding industry, antibiotic application may be the major reason causing super resistant organism to occur and propagate.In view of antibiotic harm, European Union has completely forbidden and used microbiotic for the purpose of growth promoting effects in agricultural at the beginning of 2006, and U.S.'s restricted mechanism is in this respect also more and more stricter.China is antibiotic production and uses big country, and in livestock and poultry breeding industry, the phenomenon of Irrational usage of antibiotics is very general.In recent years, State General Administration for Quality Supervision, once to a large amount of sample detecting of the dairy products in northern market, finds that antibiotic remains exceeds standard and occupies defective item first.
At present, antibiotic removal mainly contains Ozonation, Fenton reagent method, free oxychlorination method etc., but above-mentioned three kinds of methods are generally applicable in livestock breeding wastewater, the general method adopting compost removed by microbiotic for feces of livestock and poultry, and the microbiotic how in low cost, short period of time, efficient degradation feces of livestock and poultry is our current main direction of studying.
Summary of the invention
The object of the present invention is to provide the compost method of tetracycline antibiotics in a kind of efficient degradation livestock and poultry cultivation ight soil, the clearance of this compost method to tetracyclines is high, and composting material source is wide, and cost is low, and the cycle is short.
For achieving the above object, the present invention by the following technical solutions: the compost method of tetracycline antibiotics in a kind of efficient degradation feces of livestock and poultry, is characterized in that, comprise the steps:
(1) prepare composting material: maize straw, wheat stalk, Pericarppium arachidis hypogaeae and sweet potato seedling mixed according to weight percent and pulverize, regulate the humidity of fertilizer, make water content reach 65-75%;
(2) FeSO is added by composting material
4, and mix, obtain compost fertilizer;
(3) compost fertilizer and feces of livestock and poultry are mixed according to the ratio of 1:1-2, load in fermentation unit, and carry out UV-irradiation;
(4) in composting process, every 24h once ventilates, and compost is about 20-30 days, terminates compost.
Further, in described composting material, the weight percent of each component is: maize straw 30-50%, wheat stalk 30-50%, Pericarppium arachidis hypogaeae 5-15%, sweet potato seedling 5-15%.
Further, described FeSO
4addition be 2-4 ‰.
Further, the compost temperature in described composting process is 40-50 DEG C.
Further, described compost method is 89.0-92.0% to the clearance of tsiklomitsin hydrochloric acid, is 85.0-89.0% to the clearance of tetramycin hydrochloride, is 79.0-84.0% to the clearance of Chlortetracycline HCl.
The invention has the beneficial effects as follows: 1. composting material source is wide, and cost is low; 2. composting cycle is relatively short; 3. very high clearance is have to the antibiosis of tetracyclines.
