【摘要】：为解决养猪场粪污对环境污染问题,以江苏农博园为试点,进行"猪-沼-果蔬"循环农业模式和人工湿地处理研究。结果表明:粪污经沼气工程处理后,沼气用作能源;沼肥处理的葡萄穗重、粒重、产量均显著高于对照组(P005);草莓施用沼肥每667 m2增产27239 kg,其中一级果重显著增加(P005);平菇培养基添加沼渣、沼液第一潮菇平均每袋产量显著增加14582 g(P005),每袋总产量平均增加44092g,差异极显著(P001);人工湿地五级生态净化处理污水后,溶解氧显著增加061 mg/L(P005),总氮去除率8745%、总磷去除率4588%、化学需氧量(COD)减少7561%、氨氮去除率8770%,差异均极显著(P001),水质得到明显改善。"猪-沼-果蔬"循环农业模式可以实现猪场粪污的资源化利用和达标排放。
[Abstract]:In order to solve the problem of environmental pollution caused by feces from pig farms, a study on the "hog-marsh-fruit and vegetable" recycling agriculture model and the treatment of constructed wetlands was carried out in Jiangsu Agricultural Park. The results showed that the manure was treated by biogas engineering, and biogas was used as energy. The yield of strawberry was significantly higher than that of the control group (P005), the yield of strawberry increased by 27239 kg, per 667m2, and the primary fruit weight (P005) was increased significantly, and the biogas residue was added to the culture medium of Pleurotus ostreatus. The average yield per bag of the first tide mushroom in biogas liquid increased significantly by 14582 g (P005), and the total yield per bag increased by 44092 g, the difference was very significant (P001). Dissolved oxygen increased significantly (P005), total nitrogen removal rate 874545 and total phosphorus removal rate 45888.Chemical oxygen demand (COD) was reduced by 7561%, ammonia nitrogen removal rate was 8770% (P001), and water quality was obviously improved. " The pig-marsh-fruit and vegetable-recycling agriculture model can realize the utilization of pig manure and discharge to the standard.
