1. 研究目的与意义（文献综述包含参考文献）

畜禽养殖废水处理工艺 摘要:针对我国养殖业废水污染日益严重的现状，介绍了畜禽废水还田利用、自然处理以及工业化处理的优缺点、国内外应用现状以及基本内容和研究、应用进展。

新的混合工艺更能发挥各种模式的优势，使传统工艺不断优化；而种养结合的生态农业道路，实现养殖业的生态闭合循环，也是规模化畜禽养殖场废水处理和综合利用的发展趋势。

关键词：畜禽废水，废水处理，还田利用，自然处理，工业化处理 technology progresses of livestock and poultry wastewater treatment abstract: aiming at the status that the pollution of wastewater from livestock and poultry is going from bad to worse in china, some treatment technologies such as irrigation to farm land, natural treatment and industrial treatment were interviewed. the applicability, basic content, research progress and application progress of each mode are expounded. new combined processes can take the advantages of several modes and therefore optimize the traditional processes. to achieve successive disposal and utilization of livestock and poultry wastewater, it#8217;s a potential trend to choose the strcture model of combining farming and animal husbandry in agricultural ecosystem so as to balance the ecologic circle. key words :livestock wastewater; wastewater treatment; land spreading; natural treatment;industrialized treatment. 1 前言 近年来，随着我国农业结构的调整和农业产业化的推进，规模化、集约化的畜禽养殖业得以迅猛发展，成为我国农村经济中最活跃的增长点和主要的支柱产业[1 2]。

2. 研究的基本内容、问题解决措施及方案

题目：丹阳市畜禽养殖废水处理工程设计 1.工程概况： 该畜禽养殖场位于丹阳市开发区建山村，是丹阳市规模较大、较为标准化的养殖场，年存栏400头母猪，年出栏8000头仔猪，成猪2000头。

养殖场借鉴国内外先进的猪舍设计理念，现有公猪舍、母猪妊娠舍、小单元式产房、保育舍、育肥舍、后备母猪舍、隔离舍、人工授精实验室等。

生产区和生活区的明显分隔。
