This paper discusses the environmental quality objective (EQO) approach to water quality management and defines the terms EQO and environmental quality standard (EQS). The proposed list of water uses is presented. The derivation of EQSs for each use is discussed and the EQS values proposed for six list II substances are reported. The relevence of these values, and problems associated with the control of individual substances, are discussed in relation to current practice.

Ultrafiltration Process

Wastewater generated from the tofu industry usually still contains high organic pollutants that can contaminate the surface water. Therefore, it should be treated properly before it can be disposed to the environment. This study aims to evaluate the combination of coagulationflocculation and ultrafiltration methods in treating the wastewater from tofu industry. Based on the preliminary tests, the wastewater from tofu industry have pH, total dissolved solid (TDS), total suspended solid (TSS), turbidity and chemical oxygen demand (COD) of 3.4, 870 - 1080 mg/L, 370 mg/L, 446 FAU and 7954 mg/L, respectively. The coagulant and membrane used in this study were Poly aluminum chloride (PAC) and the ceramic membrane, respectively. Experimental results showed that the best pH for coagulation-flocculation process is at pH of 7.0, and this pH was then used for ultrafiltration process. The flux of the ultrafiltration membrane increased with increasing the trans membrane pressure due to increasing driving force. The observed parameters such as TSS and turbidity of wastewater decreased drastically after experiencing ultrafiltration process and met the National Environmental Quality Standard. However, the COD of water produced in the ultrafiltration process was still high and did not meet the National Environmental Quality Standard.

Water Environmental Quality

The characteristic of coal mine wastewater was introduced. Engineering design and practical run of circulator clarifier +gravity valve-less were summed up for treating wastewater of coal mine. Practice indicated that the process was steady and reliable, the effluent satisfied water quality Ⅲ standard of Surface Water Environmental Quality Standard (GB3838-2002),and there was remarkable economic results during the process of sewage treatment.

Main Influence

The analysis of marine environmental quality is an essential tool for grasping the domain environmental situation. The analysis of marine pollution source could be guide the environmental management and refine the management target. So this research is meaningful for the environmental management. In this paper, the environmental quality and pollution source are analyzed in the Beidaihe nearshore district, Tangshan Bay. The environmental quality standard of the Beidaihe nearshore district is the first level. The land pollution analysis shows that the discharge of Luanhe river has a main influence for the Beidaihe nearshore district.
