Researches on environmental biology are classified internationally into three categories of special topics: applied techniques, medium term and long term fundamentals. In most countries interests focus on the first two but fundamentals received much supports in UK and Japan. In the field of wastewater treatment and soil restoration, the removal and recovery of heavy metals, N, P, S and non-degradable organic compounds are dominated. In this paper the successful experiences of Netherland to recover the...

Review on the electrochemical methods applied to wastewater treatment were presented. Emphasis was laid on recent development in electrochemical processes, such as new materials, new techniques and novel derivative methods, in oxidative degradation or reductive dehalogenation of toxic or hardly biodegradable organic substances, in recovery of heavy metals and in electrodialytic processes. All of these make electrochemical processes more effective and efficient in wastewater treatment.
