Wastewater pollution with detergents is one of the environmental problems associated with the rational use of water resources. The existing methods of physicochemical wastewater treatment, despite their efficiency, are open to secondary environmental pollution. Biological coagulation/flocculation methods are widely used with the use of plant waste. The aim of this research is the use of ferric iron obtained by the bacterial-chemical method and bentonite to reduce the chemical oxygen demand in wastewater containing detergents. It was identified that the use of Fe2(SO4)3 obtained by the bacterial-chemical method with thionic bacteria Acidithiobacillus ferrooxidans BIT 1 and bentonite as a clay material is promising. At the same time, it was found that the highest reduction degree in the chemical oxygen demand – 88.1 ± 7.9% in wastewater was noted in the variation where the bacterial-chemical ferric iron in the amount of 1.75 g/L was used in combination with bentonite in the amount of 600 mg/L.

The current state of phosphorus-containing waste and methods of its disposal remain relevant. The storage of phosphorus-containing waste sludge is carried out in sludge collectors, which occupy large areas. With the disposal of slags and sludge, as well as the elimination of sludge collectors, the harmful effect of waste on the soil will cease, and the possibility of using these areas for economic land use will appear. Many studies show the movement of phosphorus in soil and water, thus proving the difficulty of disposing of this waste. Of course, phosphorus slags and sludge are used in small quantities in the production of building materials, but this does not solve all the problems. In the south of Kazakhstan, there are warehouses for waste from the production of phosphorus-containing fertilizers, which also require disposal. One of the ways of modern utilization of these wastes is the possibility of their use in fertilizers for agriculture. But since the phosphorus-containing waste contains a high content of phosphorus, compared to nitrogen and potassium, then with the addition of chlorella biomass, this ratio can be changed. The purpose of our study was the possibility of using a complex of phosphorus waste and algae, that is, the cultivation of chlorella at various concentrations of phosphorus-containing waste for further use of the suspension in watering the test plant. In the form of a test plant, tomato seeds were chosen, the cultivation of which in agriculture is economically profitable. When cultivated in closed ground, tomatoes lose their taste, which can be restored with the use of organic fertilizers. This article shows the results of the influence of various concentrations of phosphorus waste and green microalgae on the growth and development of Solanum lycopersicum.

On the basis of the updated educational program were discussed issues of application of design technologies, in biology lessons in the section «Cell Biology» on the method of spiral training. Communication between parents, teachers and students is provided for in project technology. The point is that interest in the topic will increase by asking questions to parents. I was asked to voice my question, share my ideas through group work. The analysis of the works of these scientists is carried out and some stages of application are noted. In order to increase the interest of students studying the subject of biology, the specifics of the use of technology in project training are determined. In the field of biology are defined stages of work aimed at further development and consolidation of data on the topic «Cell Biology». The role of the teacher was shown. Highlighted the relationship of parents with children and friendship, communication in the classroom.

One of the main challenges in pet roleum-containing wastewater treatment in municipal wastewater treatment plants is their interference with the microbiological processes of nitrogen and phosphorus removal. The purpose of the study is to assess the effect of commercial petroleum products on the conversion of nitrogen and phosphorus compounds during the biological treatment of municipal wastewater in activated sludge systems. The presence of commercial petroleum products in wastewater was found to inhibit the process of conversion of NH4-N and the absorption of PO4-P in cells. The main inhibiting effect results from additives introduced into commercial petroleum products. Variations in the removal efficiencies of NH4-N and PO4-P are due to the variable distribution of commercial petroleum products in the mixed liquor of activated sludge. An increase in the degree of dispersion of commercial petroleum products, which results in an increase in the contact surface, increases the inhibitory effect on the activated sludge process. The toxic effect of gasoline is more pronounced in comparison with diesel fuel and hydraulic oil. During the first 30 minutes of incubation of samples with oil products, an increase in the concentration of PO4-P in the solution was observed due to the death of microorganisms from toxic effects, mainly from gasoline.

The system of education in rural schools of the Republic of Kazakhstan after the collapse of the Soviet Union has experienced serious difficulties with the material support of educational process, due to the reorientation of the spiritual values of any problems with the education of students. The article describes the author's experience in creating models of organization of educational work in one of the rural schools of the South Kazakhstan region in 1988-2005 years, which later became a model for replication in many schools of the republic. The educational activities have been used as elements of Kazakh ethno-pedagogics and psychology with the involvement of the local population, as well as moments of vocational guidance on the basis of existing enterprises.
