中文摘要:
      种养结合是我国南方地区普遍采用的生态养殖模式。选择广东省12 家规模化猪场,将猪场污水 处理系统划分为四种处理模式:模式一,猪—沼—果达标排放模式;模式二,猪—沼—鱼模式;模式三,猪—沼—果— 鱼生态养殖模式;模式四:猪—沼—鱼种养结合—集中供气模式。不同处理的模式的第1 处理阶段为厌氧发酵系 统,第2 处理阶段为鱼塘等生态处理设施。废水处理系统不同处理阶段的污水监测分析结果表明,不同模式的 厌氧发酵系统粪大肠菌群具有较好的去除效果,对悬浮物及有机污染物也有一定减排作用,但对污水氮、磷营 养元素减排作用有限。第2 处理阶段中具有鱼塘等污水生态处理设施的猪场,各污染物具有较强的减排效果。 不同废水处理模式污染物减排能力综合评价结果显示,模式三减排效果最佳,其次是模式四,模式二得分较 低,模式一的减排能力较差。
英文摘要:
      The integrated planting and breeding model is widely accepted in south China. 12 large-scaled pig farms were selected and were divided into four groups according to their sewage treatment systems,the first one was defined as pannage-methane tank-planting pattern;the second one was pannage-methane tank-fishing pattern;the third one was pannage-methane tank-planting-fishing pattern and the fourth one was pannage-methane tank-fishing combined with concentrated methane supply pattern. The first sewage facility was anaerobic fermentation system and the second facility was fishpond and some other ecological engineering. The pollutant concentration in different treatment models showed that anaerobic fermentation system showed good effect on reducing fecal coliforms and in some extent,also on reducing total soluble suspends. However,the naerobic fermentation system displayed a limited purification of nitrogen and phosphorus. Fishpond and some other ecological engineering made a good performance in reducing several pollutants in sewage. A comprehensive evaluation on the capability of waste water treatment system in purifying sewage was carried out,the results showed that the third pattern was the best,followed by the fourth pattern,then the second pattern,the last one was the first pattern.
