    摘要: Sulfonated styrene polymer and/or its salt, a waste water treatment material and sludge dehydrating agent each containing the sulfonated styrene polymer and/or its salt as an effective component thereof are disclosed. The waste water treatment material is used such that sulfonated styrene polymer and/or its salt, which has viscosity of 10 mPa·S to 20,000 mPa·S at 25°C after 0.01 N to 5 N neutral salt has been added to 1 wt% water solution of the sulfonated styrene polymer and/or its salt, is added to each waste water so that waste water is purified. When a sludge dehydrating agent is required, sulfonated styrene polymer and/or its salt having a weight average molecular weight of 1,100,000 or greater is combined with a cation polymer flocculating agent or an inorganic flocculating agent.
