In some areas, to use air cooling instead of water cooling, can ease contradiction of water shortage.
In the aspect of operation cost, water cooling is more economical, but water consumption is heavy, so this way suits to be used in an area of quantity of water supply.
Air cooling and motor cooling consume little water, but their energy consumption is 2-4 times of water cooling.
This way needs professionals to maintain, supplement refrigerants, wash heat exchanger.
In the aspect of environment adaptability, water cooling needs stable water source.

Environmental pollution can be divided into air pollution, water pollution, soil pollution, radioactive pollution and noise pollution.
But as for the current environmental monitoring of the status quo, there are also some deficiencies: l Monitoring professionals are still lacking.
Although with advanced and complete monitoring equipment, there are many institutions having a shortage of monitoring professionals.
Monitoring facilities can not be used by professionals to improve the monitoring of quality.
From current actual situation, many small and medium regional stations are in great need of compound professionals.

Since water pollution accident of the Songhua River, the total of the fire wastewater caused by water pollution accidents.
Pulverous activated carbon use are used to remove most of the nitrobenzene in water and carbon sand filter is used to remove the rest of the nitrobenzene to ensure the water quality of water supply from the intake to the water pipe of water treatment works.
Set up emergency disposal team for water pollution accidents[5].After the water pollution accident caused by benzene series fire, the emergency response team for water pollution accident should be rapidly established on the scene.
State Council Joint inter-ministerial meeting environment River Basin Committees Committees Committees Expert advisory body River Basin Committees Ministry of the environment Ministry of water resource Ministry of public security Ministry of fire control Ministry of communications Figure 1 Emergency organizational system for accidental water pollution events Emergency panel.The responsibility of emergency panel is to take advantage of their personal professional knowledge and experience in order to analyse and forecast the harm and development tendency of pollution accident, put forward emergency disposal schemes and provide technical consultancy and guidance for emergency treatment.
Emergency monitoring team is composed of professionals from monitoring stations and health and anti-epidemic stations, they are responsible for the emergency monitoring of pollution accidents, arranging the fracture surface of monitoring rationally on the basis of 《environmental monitoring code 》and related national standard of water quality monitoring, detecting the type of pollutant and the degree and range of pollution with small, portable, simple and rapid detecting instrument quickly and offering scientific decision-making basis to the emergency command team and emergency panel of experts.

Navigation class specialized student an overview of the concept of honor With the development of the shipping industry in the world, an increasingly competitive shipping market, and therefore have an increasingly higher demands on the quality.In particular, maritime professionals, vocational specificity require that they not only have a solid professional quality, but also have high ideological quality.
Maritime College training maritime people as unruly ' professional institutions charged with the Mission of China's shipping industry with high quality professional.
Need to state here is, this article studies "navigation class specialized student" refers to a professional college students on water, excluding the management of navigation, ship building and repairing, or maritime graduates in broader sense also belongs to maritime students majoring in education in the context of land.
This article to Shandong Jiaotong College Maritime College as a research object, the navigation class specialized (especially water professional) student research and analysis of the concept of honor system.
After nearly a century of development, basically formed the framework of maritime education system with Chinese characteristics, training a large number of professionals for the shipping industry.

But these are different from measurement of water temperature or pH which are automatically way.
They are experimentally measured by means of skilled professionals.
After that, activate the spill valve to discharge wash water.
In actual field data is controlled by trained professionals, so the final velocity graph is displayed like controlled shape.

This point is a need for a new competition for professionals in the industry.
The non-inclusion of these skills within the professional profiles stops the innovation and business growth while the professionals are highly skilled in the technology; they will not have sustainability training which will cause the solutions to be implemented diffusely.
This level aims to train specialized professionals to its projection in the innovation and entrepreneurship: design, implementation, and management of sustainable processes, environmental impact assessment, economic and social viability of processes, safety, health, etc
Through the different levels, there will be a group of professionals that will form a synergistic whole trained to develop academic (education and training, research and development) and industrial activities creating a feedback on the progress and technological development.
- Sustainable manufacturing and nanotechnology - Sustainable Manufacturing on water, air and physical systems.

But the used water often mixes with other kinds of material at the disposal site and form a fire wastewater.
For example, in a chemical fire fighting extinguishing, if people do not pay attention to the control of the amount of water or neglect fire wastewater recycling and disposal, it will lead to Water or soil pollution caused by fire Wastewater.
(2) Fire Forces lack of environmental protection related technology and professional equipments.
But they are not professional in response to environmental emergencies.
In United States and some countries in Europe, local governments or environmental protection department will provide the fire forces with professional and technical equipment used to respond to different types of hazardous materials incidents, and regularly provide professional training of environmental protection

By introducing the process of village development planning design with the assistance of a professional team, the practical significance of this development model villages for traditional local volcanic protection and utilization is thought about.
The tradition that must protect forests and water nearby is continuing by local villagers still today.
Attracting some help from professionals and community groups, specific proposals has been provided.
To increase interest, some special landscape or space can be made, such as the courtyards, gardens, and water pools.
As participants, the professional planners and designesrs should work in the villagers' point of view, for the sake of their actual needs, formulate programs of largest feasibility.

The air handling units is consisted with an air cooler unit and direct evaporative cooling, the supply of cooling water of air coolers switched by the end of cold water.
Budget estimate and analysis of programs Evaporative cooling water chiller input power (fan and pump) is 45kW, conventional chiller cold water supply and return water temperature is 7 ˚C / 12 ˚C, water chiller performance coefficient is 4.5; high-temperature chiller supply and return water temperature is 14 ˚C / 19 ˚C, high-temperature chiller performance coefficient is 8.5; fan and pump efficiency are taken 0.7.
In actual operation must be considered post-conditions, such as operation and maintenance, if not duty-related professionals, the program should not be used in this project.
Although Option three is more economy, but its running complex and maintenance needs of professionals and improve the automatic control system.
Because it is the most affordable, easy to implement, simple and reliable water system.
