Introduction Water shortages and water pollution are two major problems all over the world.
Primary pollutant substance of livestock waste and domestic sewage are organic, nitrogen, phosphorus and other substances, grey water recycling can be widely used for urban greening, industrial cooling water, environment water, ground water and irrigation water.
But it also has some disadvantages: (1) the high investment and operating costs; (2) complex technology, requires professional management; (3) collection of sludge disposal problems; (4) domestic evaluation system does not have the appropriate industry standards and technique evaluation system.
East water western tune and south water to north every year in our country, much water is lost on the way to transport water.
They are mainly used to wash the toilet water, cooling water and wash green ground factory.

Professional qualities and skills of engineers need to be reinforced and we ought to conquer the anthropogenic factors.
The water supply section of the auxiliary boiler employs the method of dual control intermittent adjustment to keep the boiler water in the range of the setting water level.
The water source is mainly the water condensed by condenser or water coming from out of the system directly.
All steam forms steam-water mixture after heat exchange, and then it flows through the condenser in water subsystem to become water and flows to hot well to form the source of make-up water in boiler.
In consequence, we accomplish the circulation of from water to steam and then steam to water to fulfill the heating tasks.

The environmental impact indicators considered in the software include carbon footprints, water eutrophication, air acidification and energy.
Unfortunately, the results only shows carbon footprints, water eutrophication, air acidification and energy, which may be not detailed enough for application in further design optimisation.
It provides a professional tool to collect, analyse and monitor the environmental impact of products and services.
Solidworks can only define product via CAD modelling which is time consuming and complex work requiring professional knowledge, so it gets only one star in product definition character.

Each experimental teaching plan with different majors and gradually arrange experimental content, set up experimental course with different levels, and form multi-level experimental teaching system with different distinctiveness according to characteristics of professional discipline and developing trend of experiment teaching.
For example, it remains typical testes such as density test, water content test and adds triaxial comprehension test in the soil experimental teaching.
In the soil experiment, it can achieve sorts of experimental comprehension of water ratio, density, classification and compaction of soil, test students the degree of mastering theoretical knowledge by taking advantage of index formula of physic property to calculate and judgment ability to time condition of site soil.
Optimize the structure of experimental teaching staff team gradually; improve the professional quality of experimental personnel in order to ensure the level of experimental teaching and quality of experimental teaching.

Offshore shallow waters has potential resource about 500 million kw.
Disadvantage analysis Lack of professional.
Offshore wind station’s cost is mostly attributed to water depth and distance from shore[6].

The market share of China’s solar water heater has been far more than 40% in 2010, the annual production of solar photovoltaic cells accounts for about 1/4 of the world, ranking 3rd in the world.
Third, enhance independent research and development of core technology of new energy, and pay attention to the development of technical professionals, playing technology innovation capability which based on circular economy.

It can be seen that such bank collapse, mostly occurred in water-break or dry period, easily formed in the reach where poor resistance of bank soil to erosion and big water level difference between flood and low water is, for example many reaches of the middle Yangtze River.
Such collapses, occurred mostly in flood and median water period, easily formed in the reach where deep water and high speed current is.
To monitor soil mechanics properties and seepage parameters, some inbuilt professional instruments should be provided.
There may be large seepage intensity in the bank due to fast drawdown of river water level and heavy rain.

In view of the audit team members, the enterprise invited experts about cleaner production to teach professional knowledge and skills of cleaner production auditing, so that the members of the audit team could master the necessary knowledge and skills of cleaner production auditing.
Such as pulping section cylinder washing water, dust water of boiler water film etc. (2) the main raw material cost increased year by year.
Water resources had not been fully utilized and the repeated use of water rate was low Management and operation Factors 1.
Reusing slurry concentration white water of garden network; 2.
Deinking use white water; 3.Using white water jump sieve; 4.

EPKS C300 SYSTEM 1．1 Hardware and Structure of EPKS C300 EPKS C300 process controlling system is the latest autonomous system produced by Honeywell, with Windows 2000 Professional as its operation system.
Quite to the opposite, too lower drum level will fasten the speed of water vaporization due to little water and heavy load in the boiler drum.
As a result of severe change of water quantity, normal circulation between drum and water is going to be affected.
If it is not timely controlled, all water in the drum will be vaporized, water circulation will be totally ruined.
In the process of control on boiler, the main level was level of water while the auxiliary ones were steam load and water supply flow.
