  3. Being a liquid containing high organic pollutants, brewery wastewater may not only lead to environmental pollution, but also decreas e the utilization ratio of raw material used in beer production. therefore, many sc holars and breweries have paid much attention to developing new techniques for t reating and making use of brewery wastewater. this paper makes a comparison among various new techniques on the basis of analyzing the sources and characteristic s of brewery wastewater. it is concluded that a single technique can not effectiv ely remove the contamination from brewery wastewater, and only the combination of various techniques can achieve great benefits both in economy and in environment. thus, several proposals are put forward for future research
