The lichen Parmelia physodes (L.) Ach. as indicator for determination of the degree of atmospheric air pollution in  the  area contaminated by flourine and sulphur dioxide emission

On the area involved in the influence of conteminations emitted by the aluminium works and electric power plant, the degree of atmospheric air pollution was evaluated on the basis of the behaviour of healthy thallus of the lichen <i>Parmelia physodes</i>, analysis of fluorine and sulphur content in this thallus and in the bark substrate and the F and SO<sub>2</sub> concentrations in the air.

Effect of the dosage of flocculants on sludge dewatering is analyzed through the determination of sludge specific resistance to filtration. Sludge dewatering behaviors conditioned on Polymeric aluminum, PAM, fly ash and composite flocculants have been compared. The results show all the conditioning agent have help to sludge dewatering. Fly ash from electric power plant as conditioning agent can greatly reduce the specific resistance of sludge and the dewatering performance can be improved.The optimal dosage of fine powdered coal is 20g/100mL and coarse powdered coal is 30g/100mL.Powdered coal is mixed with sludge to form filter cake which is blended with coal in certain proportion to make into fuel.

In order to ensure the safety of the population around objects and industries that are sources of impact on the environment and human health, a special territory is established with a special regime of use - the sanitary protection zone (SPZ). According to the regulatory framework of Russia, the approximate size of the SPZ should be justified by the project of a sanitary protection zone with calculations of expected air pollution and levels of physical impact on atmospheric air, and confirmed by the results of field studies and measurements. This paper analyzes the requirements and possibilities for establishing the boundaries of the SPZ for a state regional electric power plant (SREPP). The paper presents an example of the established SPZ boundaries of the energy company, where all calculated indicators correspond to sanitary and construction norms and rules, and the company does not need to create a new SPZ project. The new requirements for defining the SPZ boundaries from 2018 are presented, and terms of object outline, areal object and circuit are analyzed.
