With the booming of Intensive, large-scale livestock and poultry breeding industry, it satisfied consumer and caused serious pollution on the surrounding environment at the same time.Until now, the processing and monitoring of pollutants in Livestock and poultry breeding industry focused on nitrogen, phosphorus and other organic pollutants. The report of elements of heavy metal pollution on the detection and evaluation monitoring is little. Therefore, it is necessary to establish the detection methods of waste heavy metals, and the comprehensive evaluation and analysis of various indicators, selected major pollutants to form system for evaluation of monitoring technology and the corresponding pollutants detection methods.In this study, two batches of waste and waste water samples were collected from 15 farms. Determined total nitrogen, ammonia nitrogen, total phosphorus, total copper, total iron, total arsenic, total manganese, total zinc, total magnesium, total mercury, total cadmium, total chromium and CODCr. Established detection methods of waste and heavy metals from wastewater. According to test results, in farm wastes, the content of ammonia nitrogen, total phosphorus, total copper, total arsenic and total iron were the highest in swine and total nitrogen is the highest in fowl fecal. The content of total nitrogen, ammonia nitrogen, total phosphorus and total copper is also the highest in Swine wastewater. Swine farms should be strengthened pollution controls.
