Abstract

The invention discloses a method for processing aquaculture wastewater containing antibiotics by utilizing a plant floating bed, belonging to the field of wastewater pollution treatment. The method comprises the following steps: 1) plant pre-culture: cleaning Italian rye grass, utilizing pre-configured aquaculture wastewater to acclimate and culture for 7-10 days in a laboratory, thus enabling the Italian rye grass to adapt to wastewater; and 2) wastewater treatment: adding prepared aquaculture wastewater containing antibiotics into a cuboid container slot, transplanting the Italian rye grassafter acclimation and culturing to a floating bed carrier, placing the floating bed on the surface of aquaculture wastewater, and staying for 20-35 days. The invention not only can take away a great amount of nitrogen and phosphorus nutrients from aquaculture wastewater, thus inhibiting algae growth, improving water quality, and simultaneously realizing the purpose of directly discharging or recycling aquaculture wastewater. The harvested rye grass also can be used as livestock and poultry feed or used for centralized recycling treatment, and recovery of usable nutrient elements in plant body.

Description

利用植物浮床处理含抗生素养殖废水的方法 Floating bed process using plant breeding antibiotic-containing wastewater treatment

技术领域: FIELD:

[0001] 本发明属于养殖场废水的污染防治领域,更具体地说是一种利用植物浮床处理含抗生素养殖废水的方法。 [0001] The present invention is in the field of pollution control farm waste, more particularly a floating bed process using plant breeding antibiotic-containing wastewater.

背景技术: Background technique:

[0002] 随着我国农村地区经济的快速发展,畜禽养殖业已成为农民收入的主要来源,但由于规模化养殖程度较低,大多缺乏有效的废物处理设施,因而畜禽生产所产生的污染物往往直接排入天然水体,从而导致地表水甚至地下水的污染。 [0002] With the rapid economic development of China's rural areas, livestock farming has become the main source of income of the farmers, but due to the low level of large-scale farming, most of the lack of effective waste disposal facilities, and therefore pollutants generated by livestock production often directly discharged into natural water bodies, leading to contamination of surface water and even groundwater. 磺胺类抗生素是20世纪30年代发展的一类广谱抗菌药物,在畜禽养殖领域有着广泛应用,近年来为促进动物生长发育和防治病虫害而在畜禽饲料中添加兽用抗生素在许多国家已成为一种普遍现象。 Sulfa antibiotics in the 1930s the development of a class of broad-spectrum antibiotics, has been widely applied in the field of livestock breeding, in recent years to promote animal growth and pest and added veterinary antibiotics in animal feed has been in many countries become a universal phenomenon. 但是抗生素在动物体内吸收效率很低,大部分药物未经转化以原形或代谢物的形式随粪尿排泄物排出体外,进入水环境也会引起潜在的环境风险,并最终可能对人类的健康造成不利的影响。 But antibiotics in animals absorption efficiency is very low, most of the drug in the form of non-transformed prototype or metabolites excreted with the feces and urine excretion into the aquatic environment can also cause potential environmental risks, and ultimately may have on human health in negative effect. 已有研究表明抗生素抗药性基因已在灌溉用水、养殖场附近的污水池和地下水等多种环境样品中被检出。 Studies have shown that antibiotic resistance genes have been detected in a variety of environmental samples irrigation water, sewage pond nearby farms and groundwater in.

[0003] 养殖废水的传统处理工艺主要包括氧化塘、人工湿地、堆肥以及还田模式等。 Conventional treatment [0003] including aquaculture wastewater oxidation pond, wetland, and compost to field mode. 虽然这些方法投资省、耗能小、设备简单,但都有着占地面积大、气候影响严重且容易造成地下水的二次污染等缺点。 Although these methods are low investment, low energy consumption, simple equipment, but have a large area, severe climate impacts and likely to cause secondary pollution of groundwater and other shortcomings. 近年来利用水陆生植物构建生物浮床因其不占用耕地,容易管理以及处理成本较低,作为一项水处理技术已经在富营养化水体及工农业废水等诸多领域的污染治理方面得到广泛的应用。 In recent years, the use of land and water plants to build floating rafts because it did not occupy arable land, easy to manage and deal with low cost, as a water treatment technology has been widely used in many fields of industrial and agricultural waste water eutrophic water and other pollution control .

[0004] 意大利黑麦草(Lolium multifiorum Lam.),属禾本科植物,又名多花黑麦草、一年生黑麦草。 [0004] Italian ryegrass (Lolium multifiorum Lam.), Belongs to grasses, also known as Italian ryegrass, annual ryegrass. 在春、秋季生长繁茂,须根发达,在我国长江流域以南地区广泛分布。 In spring and autumn, lush growth, fibrous roots developed, widely distributed in China south of the Yangtze River region. 多花黑麦草分蘖多,再生能力强,是目前在生物修复中广泛应用的陆生植物。 Italian ryegrass tillers, regeneration ability, terrestrial plants is currently widely used in bioremediation. 彭齐,郭沛涌等学者研究了利用黑麦草水培系统净化畜禽养殖富营养化水体中N、P,研究结果表明陆生植物黑麦草对N、P有着显著的去除效果,对NH4-N和TP去除率分别可达96^^73¾^研究表明,多花黑麦草可以促进生活污水、水产养殖废水、工业废水等多种来源污水的净化,以多花黑麦草为主构建的生态净化工程对污水的净化具有较好的环境效应、生态效应和经济效益。 Peng Qi, Guo Pei Chung and other scholars to study the use of ryegrass hydroponic system eutrophic water purification livestock N, P, results show that terrestrial plants ryegrass for N, P removal has a significant effect on the NH4- N and TP removal rates of up to 96 ^^ 73¾ ^ studies have shown that Italian ryegrass variety of sources can facilitate the purification of sewage wastewater, aquaculture wastewater, industrial wastewater, to purify Italian ryegrass-based ecological construction the project has a good environmental effects, ecological effects and economic benefits to purify sewage. 然而,这些研究大多用来削减水体中氮磷和COD等常规污染因子,但TOC的处理率70%,正是由于这些特性,所以人们没有注意到将将浮床植物技术应用于去除养殖废水中所含有抗生素的研究。 However, most of these studies used to reduce nitrogen and phosphorus in water and conventional pollutants such as COD, TOC but the treatment rate of 70%, it is precisely because of these characteristics, so people will not notice the floating bed plant breeding techniques to remove the wastewater Research containing antibiotics.

[0005] 如何治理含抗生素的养殖废水,是人们迫切希望解决的问题。 [0005] how to govern aquaculture wastewater containing antibiotics, people are eager to solve the problem. 发明内容: SUMMARY:

[0006] 1.本发明要解决的技术问题 [0006] 1. The present invention Problem to be Solved

[0007] 本发明的目的在于克服现有技术的不足,本发明提供一种利用植物浮床处理含抗生素养殖废水的方法,可以使得成本低切处理效果好,操作简便且运行稳定。 [0007] The object of the present invention is to overcome the disadvantages of the prior art, the present invention provides a method of using plant floating bed containing antibiotics aquaculture wastewater treatment, so that low cost can be cut good treatment effect, simple and stable.
