Abstract

Vietnam standards include TCVN 2000 and TCVN 2001 were enforced to overcome disadvandges of old standards enforced in 1995. They also mention to geographical position, discharge loading and application. TCVN 2000 and TCVN 2001 were established and assessed that they are sensible and conformable with practice. However, these standards have some disadvantages. The current standards are applied to all kinds of industrial wastewater. At present, there have no specific standard applied to particular industry so it is so trict to one industry but easy to anothers. This study aims to propose discharge standard which based on discharge loading, concentration and raw wastewater characteristics of some typical industries such as textile, latex, paper, alcohol and leakage. The proposal is based on the assessing method of toxicity of treated wastewater after releasing to effluent receiving. Keywords: Vietnam standard, discharge standard, induatrial wastewater, concentration, emission flow rate, effluent receiving.
