Analysis methods of TPA in environmental samples, action and rule of TPA in wastewater treatment model system, and utilization of wastewater containing TPA from oxided xylene were studied. Method of reverse phase HPLC, determining TPA in environmental samples, was simple, sensitive and reliable. Mobile phase was 15% methanol/85% water, pH3.5-4.5, containing accetic acid. Sample was fixed with chloroform and could be preserved enough time (over 4 months) to be determined. TPA could be degraded easily in the urban sewedge treatment system. Aeromonas and Xanthmonas which could degraded TPA were isolated from treatment system. Degradation rate was closely related with temperature, dissolved oxygen, remain time and aquatic plant. Relation with temperature can be described by the mathematical equation. Acutic toxicity of TPA for fish and aquatic plant were very low. Accumulation of TPA in deposit and aquatic plant were too low to reach dangerous level. Settling precipitation with limewash treated wastewater containing TPA was good method. TPA wastewater could treated with traditional facultative lagoons and aerated lagoons, effection were better. The methods mentioned above were inadequate. Comperhensive utilization technique containing economic, social and environmental benifits were put forward in our paper. Undoubtedly, this method was the best one of methods of control and treatment wastewater containing TPA.
