This article raises questions about development housing in planning structure in the town of Orenburg. The author talks about the development housing since founding of the town of Orenburg and identifies the main historical stages and living buildings. The main attention is on the development housing at the modern time. For the most part it is new type of housing for example multi-storey residential complex, townhouse, individual dwelling. On the basis of the analysis, that was made the author gives some recommendations for the further development of the housing policy of Orenburg.

The article reports on the research results of wastewater’s biological treatment at Novokuibyshevsk oil refining plant using the technology of nitrification - denitrification. The paper reveals the possibility of meeting modern requirements for treated water quality by nitrogen compounds while treating industrial wastewater without mixing it with municipal wastewater. Necessary dependencies and technological parameters for choosing the mode of experimental and production use of treatment structures by one-stage scheme with nitrification-denitrification are given.

A promising use of waterworks sludge as soil, which would solve both the reclamation and recycling of sludge treatment plant. Based on the experimental studies on the structure, chemical composition and fertilizing properties of sludge shows a possible implementation of the feasibility of the process.

Supercritical water flow passing through the broadcrested weir has been experimentally examined. Engineering-based results on hydraulic-jump wave length and conjugated depths measurement considering the weir geometrical characteristics changers.

There are considered notions of ecological and industrial safety. There are given examples of the damage of structures of industrial buildings. There are considered reasons of occurrence of possible accidents of buildings at the industrial enterprises and the drawbacks of the system of industrial safety of buildings and structures.

Water treatment and returning the treated water into the production is very important for refining and petrochemical industries. The technical condition of wastewater and water treatment with characteristic lesions of structural elements significantly affect the ecology of the environment and the plant area with flooding possible contamination of groundwater. These issues are discussed based on a survey of individual objects petrochemicals.

The article reports on theoretical research results of sand free lightweight concrete wall stones’ thermal protective properties. Calculated values of resistance referred to stone wall masonry’s thermal exchange on cement-sand and “warm” mortars are got using the method worked out by the article writersCalculation of three-dimension thermal fields in the external wall fragment was performed by using the method of finite elements provided in “ANSIS” software package.

Presents the results of the analysis of efficiency of application of the harmonized automatic control modes of operation of the burner and the drive boot the rotary kiln for firing of expanded clay. On the example of the furnace size of× 40 m, in which fired raw clay smushlaevsk’s Deposit, the possibility to reduce energy consumption for production of 1 m 3 of expanded clay 11-to 15 %.
