The final destination of PCBs in the environmental system is soil and sediment due to its highly distribution coefficient between sediment and water.
Widely used in the determination of PCBs in soil, water and air.
At present, the United States make more studies about polychlorinated biphenyls in soil and water environment in biodegradation process.

The study of the techniques used in Bahia and the NTE E.080: 2000 Norm from Peru In this study there was hold a data survey through a local study that was done in edifications with adobe brick and that were executed by professional – or nonprofessional – construction workers in four cities from the State of Bahia – Brazil.
After crushing the mixture of soil and water, rest it for 24 hours.
After crushing the mixture of soil and water there was not a rest of the mortar.
After crushing the mixture of soil and water there was not a rest of the mortar.
This latex was also used as a water repellent material in masonries of Camaçari House (construction worker “C”), and it had turned the walls more repellent to water and the walls had even become more durable.

Before I studied Zen for thirty years, I saw mountains as mountains and waters as waters.
For it is just that I see mountains once again as mountains and waters once again as waters.
One of the major aims of this paper is to analysis how much “ meaning” excluded to professional knowledge can be conveyed by buildings or cities.
Its water is so clear and clean that it has reached drinking water standard.
One is the Milky Way that transit from concrete water in the traditional form to abstract water in modern times.

This study focuses on the energy and exergy analysis of a IMS-VCRS in a water-cooled centrifugal chiller using four distinct refrigerants.
Thus, R513a and R515a are azeotropic mixtures with low GWP and good thermodynamic properties, used as a substitute for R134a in a water-cooled centrifugal chiller [2,3].
A highly superheated vapor then enters the condenser, utilizing a water-cooled system to release heat into the water following the second-law of thermodynamics.
Therefore, it can be concluded that the IMS-VCRS is an energy-efficient cooling system that can be applied to a water-cooled centrifugal chiller to achieve better performance.

In this paper, by citing an example of the southern settlements in Jinan, combined with the factors of its geographical location, natural surroundings and geological conditions, we’ll talk about the motives for “Stub-End Type” Spatial Development and relevant solutions and means from a professional point of view to have healthy and harmonious development of Stub-End Type Residential Area.
Among the city, discharging flood in 110 square kilometers in the southern mountainous area mainly flowed into Hero Mountain Road, Shun Geng Road and Second Ring Road and other city roads, with high velocity and ferocity, the water flowed in same sections with the maximum flow rate of the 3 ~ 4 m • s-1[1], which caused flood similar to torrent in the street.
The design for straight of north-south road and man-made drainage channel blocking made the road less ability to discharge flood, which caused flooding water in urban area seriously.
In the process of constructing the current roads, building houses and smoothing the ground and other projects, we should increase the coverage of green area, improve the permeability of the ground to reduce the coefficient of runoff, all of which would successfully allow no water flowing on the ground after rainstorms.
In addition, in the southern “Stub-End Type” Settlements , we should plan to construct the drainage systems district by district and set the spillway; constructing the dams or reservoirs chains around the deeper ditch for discharging near the residential region, implementing control layer by layer and storing water section by section, examining the rainwater drainage system and sewage pipes to make sure that rain and sewage diversions are in good condition.

Secondly, the unreasonable structure of water supply, low efficiency of unconventional water’s (recycled water) and seawater intrusion, made the frequency and extent of the drought intensified in recent years.
In addition, because of the South Fort zone, Jidong Oilfield and marine aquaculture industry pollution, the coastal water environment is very bad. 4)Sea water invasion risks.
The long-term over-exploitation of underground water destroys the balance between fresh water and sea water, causing sea water or high salinity water invasion.
At the meanwhile, with the influence of the tide, sea water dates back to the low-lying inland areas along with the water at the Luan River system.
Main countermeasures: to establish monitoring and forecasting system; to establish flood and drought warning system and evaluation system; to raise the standard of urban flood control and drainage, and to ensure the quality of flood projects. 4)Sea water intrusion countermeasures Main countermeasures: to find more fresh water resources, to control groundwater exploitation strictly, to make the comprehensive utilization of water resources; to enhance groundwater recharge, and build water curtain, to take active measures to control the sea water intrusion; to conduct water quality monitoring and forecasting, and to do water reserves surveys.

Water paint limousine technology.
Furthermore, water saving problem of pretreatment technology shall be concerned.
Generally water consumption occupies the largest, around 90% of total water consumption in painting workshop.
In order to save water resource, reduce sewage discharge throughput and achieve the same washing cleanness, water consumption shall be as small as possible.

Water removal during drying may be controlled by external and/or internal resistance to mass transfer [2,3].
The external resistance controls the water transfer from the solid surface to the gas medium.
For that purpose, the Generalized Reduced Gradient (GRG) optimization method available in the Microsoft Excel spreadsheet from Microsoft Office XP Professional was used.
As a whole, ultrasound increased significantly (p<0.05) water diffusion inside the solid, as well as the water transfer from the solid surface to gas phase.

The groundwater in Jinjiang includes interstitial water in loose rock, pore-fissure water in weathering zone, and bedrock fissure water [6].
Shallow groundwater refers to the phreatic water and the feeble confined water that are 20-50 meters underground [7].
