Sulfur dyes are inexpensive and mainly used for coloring cellulosic textile materials or mixtures of cellulosic fibers. Sodium sulfite is relatively inexpensive and considered as traditional reducing agents and used for sulfur dyes and dyeing, But touch it, is toxic and dangerous.Using it may be Leave harmful residues on fabrics completed and and produces wastewater which it’s treatment is difficult and damage to the environment.
Textile industries are met with high cost of water and wastewater treatment, as well as stringent environmental regulations.
In this study, a variety of methods, including methods of physical, chemical and biological treatment of industrial wastewater containing paint application of sulfur was investigated
This study concludes with recommendations for additional measures to improve treatment processes that can be done from both a technical and economic point of view.

Nowadays one of the most important global issues is environmental problems that can cause harm to human and other organisms. Because of these problems we need to find strategies for solving them. One of the most important problems in the world is the pollution produced by different industries like oil industry that has a significant role in the nations economic and progress. There are many solutions and methods for surveying and mitigating the industries effects.
Multiple Criteria Decision-Making (MCDM) is one of these methods that order alternatives based on their importance. Ranking problems consist in rank ordering of all alternatives from the worst to the best, looking at their evaluations on the considered criteria. In present study two more important outranking methods (PROMETHEE and ELECTRE) were assessed and their advantages and disadvantages were surveyed. Also a study was done in Arak petrochemical industry by PROMETHEE method as a case study and construction phase alternatives were ranked by mentioned method.
Case study investigation and review on other studies showed that the PROMEHTEE method because of some features like being easy to use, understandable, Ability to cope with uncertainty, importance the decision makers, ability of visual representation, validity and flexibility is more applicable than ELECTRE.
So the suggested method can be applied for making environmental decisions and also oil and petrochemical industries that simultaneously deal with qualitative and quantitative data and uncertainty. The researchers hope that it would have desirable results.

The issue of environmental pollution has become a significant issue in today’s world. Environmental pollution, mainly caused by toxicantsm, includes air, water, and soil pollution. The results of this contamination are not only destroying biodiversity, but also endanger human health. Nanotechnology offers many advantages to improve existing environmental technologies and creates new technology that is better than current technology. In this sense, nanotechnology has three main capabilities that can be applied in the fields of environment, including the cleanup (remediation) and purification, the detection of contaminants (sensing and detection), and the pollution prevention.
Advances in nano-scale science and engineering showed that many of the current problems involving air quality can be solved. This article gives an overview of application of nano materials in air purification. We highlight recent advances on the development of novel nano-scale materials and processes for reducing emissions.
Key words: Nanotechnology, Air Pollution, Environment.

Environmental Impact Assessment (EIA) is a process of identifying, predicting and mitigating the negative impacts of development projects on physico-Chemical, biological, socio-economic and cultural environments. The main purpose of EIA process is to inform decision makers of the likely impacts of a proposal before a decision is made. EIA provides an opportunity to identify key issues and stakeholders early in the life of a proposal so that potentially adverse impacts can be addressed before final approval decisions are made. There are different methods for implementing an EIA project. The best method is one, which can quantify the impacts and assess the impacts rapidly. This paper attempts to investigate and compare capabilities of the EIA prevalent methods including questionnaire, matrix, system analysis, maps overlay, networks and ELECTRE-TRI multi-criteria decision method. This paper indicates that ELECTRE_TRI is an appropriate method for EIA projects. However, the final judgment of the selection of EIA method depends on the EIA experts opinions.

Earth-Sheltered Building, an Idea Compatible with Environment
Fatemeh Akrami Abarghuie(Corresponding Author)
Chemical pollution caused by the production of building materials, carbon dioxide emissions and particulate matter released into the air, including the major environmental pollution affecting the construction industry. Also a lot of fuel and natural resources consumes to provide heating and cooling of buildings, financing future of generations and the environment at risk. Moreover, the removal part of virgin land in certain areas and replace it with a special mass, disrupts the ecosystem of the region. Therefore, it is essential to design strategies in new buildings, with the aim of environmental harmony. So to achieve this aim, the design of the building with the idea of compatibility with the environment has long been considered among different communities. Earth-Sheltered Building such examples that follows energy idea for reducing building energy consumption. This study discusses how to organize the building and its environmental impacts associated with the environment is concerned. Depending on the capabilities this type of architecture to reduce the consumption of fuel and energy, as well as environmental compatibility, it can propose for contemporary architectural and urban purposes.

This research aims to increase citizen participation in the implementation and operation of wastewater projects, through the implementation of training practices in order to reduce the technical, economic, social and environmental issues were investigated. This research was a descriptive - analytical techniques using a questionnaire and completing the form field by the citizens .The population of area study is 384 samples and also waste water company.
Data Software SPSS18 in both descriptive and inferential statistics was analyzed. To evaluate data normality test, Kolmogorov - Smirnov one-sample t-test for hypothesis testing, when both test and Spearman correlation test, using the proposed two hypotheses were confirmed.
The assumptions include Public participation in the implementation and operation of the sewage effective. Implementation of teaching practices in the implementation and operation of the sewage effective.
The results show that there is a relationship between the level of awareness and education. Also whatever is the best job in the community's awareness of the wastewater collection, the greater?
Factors such as the lack of interest and public participation initiatives can waste management problems, economic and social costs, informing noted.
According to the results, the implementation of training practices to increase citizen participation in infrastructure projects as a major metropolitan wastewater will be effective.
