The article is devoted to the study of the prospects of using compost with sewage sludge in the raw material for the recultivation of disturbed lands. A special installation was used for bio-composting, which allowed controlling of the process parameters. The results of bio-indication of composts obtained under different conditions of compositions of the raw material mixture are given. Based on the analysis of the results of bio-indication, the optimal composition of the raw material mixture using "fresh" and "old" sewage sludge is established.
The aim of the work is to improve the methods and tools of multi-spectral measurement control to improve the accuracy of monitoring the integral parameters of wastewater pollution, which is necessary to ensure their effective purification using higher aquatic plants. The complex for wastewater treatment is improved, which is supplemented with the multi-spectral monitoring system of integrated pollution parameters.
