污泥处理目前仍然是辣手问题。大量污泥投入深海,或埋入地表,往往造成污染,影响生态平衡。工业污泥作为肥料,受到重金属等有害物质的限制。污泥造气发电,效率较低(25%左右),尚难推广。利用活性污泥制成生化纤维板,强度可达到国家三级硬质纤维板标准,但因成品有臭味,还需进一步 Sludge treatment is still a hot hand problem. A large amount of sludge is thrown into the deep sea or buried in the ground, which often causes pollution and affects the ecological balance. Industrial sludge, as a fertilizer, is restricted by harmful substances such as heavy metals. Sludge gasification power generation is less efficient (around 25%), and it is difficult to promote it. The use of activated sludge made of bio-fibre board, the strength can reach the national three-level hardboard standards, but because of the smell of the finished product, but also need to be further
