【摘要】：在工业污染和生活污染受到日益重视,处理技术日趋完善,国家政策和资金不断投入的大环境下,工业源和生活源的污染治理已经取得了较大的成效。而四川省作为农业大省,畜禽养殖污染作为农业污染源的重要组成部分,因其被处理模式灵活多样、所在地区普遍经济水平和管理水平较低等多种因素制约,已经逐渐成为部分地区经济发展和环境保护的主要矛盾。本文以四川省环境保护厅常态科研课题“四川省环境污染防治技术水平与绩效评估-水污染防治卷”为依托,2011年四川省环境保护厅环境统计数据为主要依据。论文通过大量文献资料的调研和实地调查,从四川省畜禽养殖业的规模与分布、主要污染物总量及地域差异、畜禽养殖污染治理效果及资金投入情况等多方面评估了四川省畜禽养殖污染防治现状,筛选四川省范围内112家具有代表性的规模化畜禽养殖企业为评估背景,选取化学需氧量去除率、氨氮去除率、总磷去除率三个污染治理效果指标,配套农业面积、有机肥转化率、沼气转化率、干清粪和发酵床养殖模式四个减量化、无害化、资源化指标,提出了针对规模化畜禽养殖企业污染防治水平的评估模型,结合处理规模,对规模化畜禽养殖企业污染治理模式进行绩效评估。在对现状进行全面评估之后,论文基于2011年四川省环境保护厅环境统计数据,分别从污染预防技术；减量化、无害化、资源化技术；末端治理技术三个方面进行研究,构建了四川省畜禽养殖污染防治体系,并总结出适合四川省现状的畜禽养殖污染防治技术,进而根据养殖规模提出最佳可行组合技术。结合四川规模化畜禽养殖污染治理实际工程,通过典型案例研究,进一步验证了畜禽养殖污染防治最佳可行组合技术的实用性。本研究可为四川省畜禽养殖污染防治提供理论依据和决策参考。
[Abstract]:Under the environment of industrial pollution and domestic pollution being paid more and more attention to, the treatment technology is becoming more and more perfect, and the national policies and funds have been continuously invested, the pollution control of industrial and living sources has made great achievements.As a big agricultural province in Sichuan Province, livestock and poultry pollution is an important part of agricultural pollution source, which is restricted by many factors, such as flexible and diverse treatment modes, low general economic level and low management level in the region.It has gradually become the main contradiction between economic development and environmental protection in some areas.This paper is based on the normal scientific research project of Sichuan Provincial Environmental Protection Department, "Technical level and performance Evaluation of Environmental pollution Control in Sichuan Province-Water pollution Prevention Volume", and the environmental statistics data of Sichuan Environmental Protection Agency in 2011 as the main basis.Based on the investigation and field investigation of a large number of documents and materials, the paper analyzes the scale and distribution of livestock and poultry breeding industry in Sichuan Province, the total amount of main pollutants and the regional differences.The present situation of pollution control of livestock and poultry culture in Sichuan Province was evaluated from many aspects, such as the effect of pollution control of livestock and poultry culture and the investment of funds, and the 112 representative large-scale livestock and poultry breeding enterprises in Sichuan province were selected as the evaluation background.Chemical oxygen demand removal rate, ammonia nitrogen removal rate, total phosphorus removal rate, three pollution control effect indexes, supporting agricultural area, organic fertilizer conversion rate, biogas conversion rate, dry defecation and fermenting bed culture mode, were selected.The evaluation model of pollution prevention and control level of large-scale livestock and poultry breeding enterprises was put forward. Combined with the scale of treatment, the performance evaluation of pollution control mode of large-scale livestock and poultry breeding enterprises was carried out.After a comprehensive assessment of the status quo, based on the environmental statistics data of Sichuan Provincial Environmental Protection Agency in 2011, the paper studies pollution prevention technology, reduction, innocuity, resource utilization technology and terminal treatment technology, respectively.The pollution prevention and control system of livestock and poultry culture in Sichuan province was constructed, and the technology of pollution prevention and control of livestock and poultry culture suitable for the present situation in Sichuan province was summarized, and the best feasible combination technology was put forward according to the scale of breeding.Combined with the practical project of large-scale livestock and poultry pollution control in Sichuan, the practicability of the best feasible combination technology of livestock and poultry pollution prevention and control was further verified through typical case study.This study can provide theoretical basis and decision-making reference for the prevention and control of livestock and poultry pollution in Sichuan province.
