摘要：
The discharge of the mechanically treated waste water of a waste paper mill to the regional sewer system caused several environmental problems. Investigations have been carried out to find the optimal solution for these problems. Convenient solutions turned out to be the pretreatment of this waste water by either the high-rate activated sludge process or a high-rate anaerobic process combined with an activated sludge posttreatment. Mainly because of lower total costs, an anaerobic-aerobic pretreatment plant with an UASB reactor has been erected. The plant has in been in operation for three months and the operational results are satisfying.
