Abstract
The effective purification of large-capacity wastewater from heavy non-ferrous metals and organic pollutants using inexpensive sorption technology remains a crucial task. Analyzing the current objectives of sustainable development, biochar obtained from chicken manure has prospects as a source for sorption purification of industrial wastewater. To determine the characteristics of organic material and the composition of the initial and equilibrium phases, the following analysis methods were used: volumetric, complexometric, pH-metric, X-ray fluorescence, chromatographic, spectrophotometric, luminescence-photometric and X-ray diffraction. The thermal nitrogen desorption method was used for determining the specific surface area and pore sizes with the Quantachrome Nova 1000e automatic analyzer. The sorption properties of the reprocessing product of the fresh poultry manure were investigated in relation to organic and inorganic compounds: phenols, benzene, ketones, cations of lead, mercury, manganese and iron. Based on the results obtained, technical conditions were developed for the use of the reprocessed organic waste-based product as a sorption material for household, industrial and technological wastewater purification from organic and inorganic components.
Highlights
A prerequisite for the creation of sustainable industrial technologies is their compliance with the formulated principles of green chemistry, the creation of safe components, the minimization of waste generation, and the use of renewable resources [1,2].The use of by-products or secondary resources of the main technological lines, for the effective purification of large-capacity wastewater from heavy non-ferrous metals and organic pollutants using inexpensive sorption technology, remains a crucial task [3,4]
Analyzing the current objectives of sustainable development [8,9,10], it was found that biochar obtained from chicken manure has prospects as a source for water purification in many parts of the world
In [11], the effectiveness of biochar based on peanut shells and untreated peanut shells for the removal of arsenites and arsenates from aqueous solutions was investigated

Analyzing the current objectives of sustainable development [8,9,10], it was found that biochar obtained from chicken manure has prospects as a source for water purification in many parts of the world. In [11], the effectiveness of biochar based on peanut shells and untreated peanut shells for the removal of arsenites and arsenates from aqueous solutions was investigated. The experimental results showed that biochar has a higher efficiency than peanut shells: arsenites were removed at 95% effectiveness at pH = 7.2 and arsenates were removed at
