Abstract Bioretention system is an effective way to solve the problem of urban water environment pollution. In this paper, the difficulty of the existing biological retention system to effectively remove dissolved heavy metals was studied. By comparing the adsorption effect of acid quartz sand filler layers with nano-hydroxyapatite (N-HAP), medical stone, nano-carbon, and biochar, the conclusion is drawn from the static and cylinder dynamic experiments that N-HAP has the best effect of removing Cu2+ and Zn2+, and the effect is long lasting. The scanning electron microscopy results showed that the N-HAP particles were rough and the surface was more rod-shaped, which increased the specific surface area of the N-HAP particles, promoted the complexation and electrostatic interaction of the additives and heavy metal solutions, and facilitated the adsorption of heavy metals. The research results help to improve the technology of filler matrix modification.

In this article, the results of predicted environmental pollution load of air, water and solid waste by the operation of the park / industrial zones in Long An province by 2020 are presented. Two mathematic model, ISC3 and Mike 11, were used to determine the spread of environmental pollution of air and water. The results showed that, to make the air environment quality meet QCVN standard, we need to cut gas emission to 57% by 2015 and 80% by 2020. For water environment, the forecast maps on spread of water pollution can help to identify the source that cause water pollution.

The problem of water pollution in India is not a new one. It has been an age- old practice that people dispose of their waste into rivers and other water bodies. The consumption of polluted water is intimately connected with the occurrence of many deadly diseases. Rapid and unplanned population growth in India is a key factor to the whole equation of water pollution. This paper provides an overview of population growth, the mechanism of water pollutant load, causes of water pollution in India as well as the diseases resulting from the use of polluted water.

White Pepper

White pepper is a high value product being preferred by the markets of developed countries. However, the white pepper production time is too long and the procedure needs large amount of water. Our research offered two solutions to over come these disadvantages gradually. The shelling yield of black pepper that was immersed in water with the ratio of 1:1 ( W: W) at 35 oC in 48 hours, was 92.2%. In the case that black pepper was in water with the ratio of 1:1 (W:W) and pectinase with the dose of 4 UI/ 50gr pepper, inculation at 40 oC in 4 hours and then at room temperatmein 24 hours, the effectiveness of removing the husk of the pepper reaches 93.2 % and the content of piperine in white pepper was 6.58 percents. This procedure shortens the time of immersing the pepper and reduces the amount of used water environment pollution.
