Physiochemical analysis of polluted water samples collected from vicinity of National Highway was carried out. Different parameters like pH, TDS, BOD, COD, DO and different heavy metals were determined by standard analytical methods. The result observed that the waste water pollution load is decreased when the distance increased from NH. Polluted water besides NH indicates high pollutant load. Polluted water with more pollutants not treated properly is act as source for other pollution like soil, air and water through leaching, percolation, weathering and downstream flow. Hence, proper management and amendment of polluted water bodies caused by vehicular emission on the both side and around National Highway is essential for human health and environmental protection.

Water is the basis of natural resources and strategic economic resources.Deteriorated water environment of streams in Shenzhen city could have a great impact on ecological safety, people's health,and economic development.Based on the data of field observation and Remote sensing (RS) image,integrated analysis of the water degradation causes,and the changes of biochemical oxygen demand in five days(BOD5）concentration by mathematical model were carried out,which is on basis of percentage of waste water disposal,fresh water transformation,and harbor excavation, respectively.The results show that degradation causes of water quality were resulted from waste water discharge, harbor construction,and ecological environment damage, which could lead to slowly water exchange. Accordingly,the pollution can be easily to store in the bay,which result in water quality changes.The most important improved countermeasure is the control of waste water, which could be had a great effectiveness to decrease pollution.In addition, fresh water must be supplied after polluted water was cut off,which can be better improvement for water quality.This would be extreme improvement for hydrological dynamics due to 15m harbor excavation,which can significantly reduce BOD5 concentration.The innovation points of this paper is to mathematical model,which is based on the basis of qualitative analysis.

Microalgae Growth

Tofu industries produce waste water containing high organic contents and suspendid solid which is harmful if directly discharged to the environment. This waste can lead to disruption of water quality and lowering the environmental carrying capacity of waters around the tofu industries. Besides, the tofu waste water still contains high nitrogen contents which can be used for microalgae growth. This study was aimed to reduce the pollution load (chemical oxygen demand-COD) of tofue wastewater by using ozone treatments and to utilize nutrients in treated tofu waste water as medium growth of microalgae. The result showed that the reduction of COD by implementation of ozone treatment followed first order kinetic. Under variation of waste concentrations between 10-40%, the degradation rate constant was in the range of 0.00237-0.0149 min-1. The microalgae was able to grow in the tofue waste medium by the growth rate constants of 0.15-0.29 day-1. This study concluded that tofu waste was highly potent for microalgae growth.

This paper reflects, from an industrialist's perspective, on 25 years' operation of the Water Pollution Act in The Netherlands. The Act empowers Water Boards to implement national policy on water quality. These Boards may be regarded as a model for cooperation between the general public and industry, two partners that are both polluters and sufferers from pollution. Oxygen-consuming and heavy metal pollutants are considered as examples of the significant improvements achieved over the past quarter century.
