Introduction Membrane distillation (MD) is an important technology to realize the utilization of wastewater resources, water saving and emission reduction [1-3].
Data Processing. (1) The equivalent flux J, kg·m-2·h-1, was calculated as following: (1) where is the increase of the total water production in the measurement time, kg, and S is effective membrane area in main evaporation zone, m2, and t is the measurement time, h

This paper proposes the use of produced water sewage treatment for desalination of sea sand , sand can be fully washed river sand while achieving reduction in fresh water usage and purpose .
Compressive strength data shows that when the chloride ion did not deal with sand to a certain extent , the strength of concrete and the concrete has a significant difference of ordinary river sand .

Fig. 2 The Presiselect device for abrasive sieving Hardware and software for data processing Hardware For the scanning of vibrations a miniature piezoelectric accelerometer manufactured by Brüel & Kjær type: 4507-B-004 was used.
- with the increasing numerical value of sieved abrasive mass flow in the studied range the vibrations acceleration amplitude periodically increases and compared to the abrasive mass flow of 200 and 600 g/min it increased by 20.42 % - with the increasing numerical value of non-sieved abrasive mass flow in the studied range the vibrations acceleration amplitude at first decreases to a minimum value of 0.326 mg at mass flow of 400 g/min and then it slightly increases - compared to the mass flow 200 g/min and 400 g/min of non-sieved abrasive is the vibrations acceleration amplitude reduced by 27.07 % - with the increasing mass flow numerical value of sieved abrasive in comparison to non-sieved in the studied range is the vibrations acceleration amplitude significantly reduced from value of 1.425 mg to value of 0.326 mg at mass flow of 400 g/min and at mass flow of 600 g/min from value of 1.425 mg to value of 0.347 mg - in comparison of sieved and non-sieved abrasive is the biggest reduction

This is clearly seen in Fig. 3, where data of the specific energy input of Ar+ ions in Al, Cu, and W targets are presented at the same irradiation mode.
A considerable growth of Wm results from the reduction of the beam diameter, i.e. with increasing beam current density.

vertical direction. 2 Hanging material hit people. 1 It violated safety regulation for operation that throwing materials. 3 Vehicle hurt people. 2 The electrician doesn’t do the power transmission according to the prescribed procedure. 3 The safe voltage is not used in moist place. 2 The equipment is not be powered off when it is out of use. 2 The electric welding is operated by non-professional welder. 4 The welding line and loop zero line is not in place completely. 2 The equipment was not out of service according to regulations when it was found that there is something wrong with it. 2 The hand-held electric tools are used before resistance test. 1 Electro-gas welding is operated illegally, there is hole which is not sealed up under the working place vertically. 3 Lengthen power line or change plug illegally with hand-held electric tools. 2 3 The personnel safety risk factor analysis of electromechanical installation project in construction phase 3.1 Questionnaire design and data
Therefore the scale has higher reliability. 3.2 The factor analysis Factor analysis is the promotion and development of the principal component analysis, and it also belongs to the multivariate analysis process of dimension reduction.

However, when the admixture is over 20%, the reduction is not that obvious.
But there are still disputes about the influence of one-day silica fume on the autogenous shrinkage of concrete, which remains to be further observed through tests and theoretical analysis, aiming to draw an appropriate and accurate conclusion. 2 Relationship between early-age autogenous shrinkage and the amount of mineral admixtures Regression analysis has been conducted for the current domestic test data[2, 4, 8, 10, 12], and it has been discovered that there is a remarkable linear dependence between the early-age autogenous shrinkage and the fly ash, ground slag and silica fume admixtures, which can be described with the following formula

A study of data dedicated to the application of natural zeolites and published after 2003 was carried out in our project [7].
Fig. 3.Block diagram of technical process of waste waters purification from ammonium ions Block diagram of two stage process, consisting of combination – absorption of the basic mass of ammonium ion (concentration reductionfrom 2000 mg/l to 20 mg/l) by treatment with powder NZ in the stirred reactor and dynamic advanced treatment (concentration reduction from 20 mg/l to 2 mg/l or less) is shown in fig. 3.

Over the years, various types of Fe3O4 nanostructures, including spheres [11], wires [12], fractals [13], hollow structures [14], and nanosheets [15] have been prepared by different synthesis methods, such as reduction of hematite [16], co-precipitation route [17], microwave plasma synthesis [18], microemulsion methods [19], ultrasound irradiation [20], hydrothermal process [21], and so on.
The data is consistent with the values in the literature [29], which further proves the composition of the magnetic Fe3O4.

The geologic data reference the report of geotechnical investigation on west fourth ring Fuxing road.

Table 4 displays the crystallographic data used for phase determination from the ICDD-database.
In the future the focus has to be on the reduction of carbide formation during thermal processing due to the adjustment of the sintering atmosphere.
