基于禽畜养殖水体污染现状构建沼气蓄热温室生态系统研究

Research on Construction of Biogas Heat Storage Greenhouse Ecosystem Based on Water Pollution of Poultry and Livestock Farming

以松前村为研究对象,调查研究该村畜禽养殖业对环境的污染状况,从而构建沼气蓄热温室生态系统,该系统利用太阳能加热沼气池,一方面为生态大棚提供必要温度,另一方面可对大棚内土壤进行堆肥。该系统模式可减少其COD、氮、磷等污染物质含量,达到排放标准,减轻对地表水体污染。

In this study, Songqian Village is taken as the research object to investigate the environmental pollution caused by livestock and poultry breeding in the village, so as to construct the biogas heat storage greenhouse ecosystem. This system uses solar energy to heat the biogas digester, providing necessary temperature for the ecological greenhouse on one hand, and composting the soil in the greenhouse on the other hand. The system model can reduce the content of COD, nitrogen, phosphorusand other pollutants, meet the emission standards, and reduce the pollution to surface water.
