The production of building materials is a significant reserve for increasing productivity and solving many environmental and economic problems in the construction industry. The use of any production waste in construction, especially liquid dehydrated galvanic waste, should ensure the environmental safety of their preparation and use, which are considered in the scope of the presented research. The work involves consideration of research results, which consist in the development of a block diagram of biological testing and the obtained tabular values, due to biological testing of certain types of building materials. Based on the obtained practical results, the optimal values for construction products have been developed, which determine the condition of construction materials through the use of biotesting. As a result of approbation of several test schemes, the practical values of input and heat-treated sludge (g / dm3), masonry mortar (%) and reinforced concrete with sludge additive (%) were obtained. Dunaliella-degree of immobilization for 5 days. (%); Elodéa canadénsis - the degree of inhibition of growth in length (% to control) at exposure (ext.) And Daphnia - survival at 48 days of exposure (%). The practical scheme and optimum values of production of building materials are offered, the initial application of use of products of biological testing (ceramic tiles with the addition of slime and other products with slime waste) is substantiated.
建筑材料的生产是提高生产力和解决建筑行业许多环境和经济问题的重要储备。在建筑中使用任何生产废弃物，特别是液体脱水电废物，都应确保其制备和使用的环境安全，这是本研究范围内考虑的问题。这项工作涉及考虑研究结果，其中包括制定生物测试的框图和由于对某些类型的建筑材料进行生物测试而获得的表格值。根据所获得的实际结果，提出了建筑产品的最优值，通过生物试验确定建筑材料的状态。通过对几种试验方案的认可，得出了投入量和热处理污泥(g / dm3)、砌体砂浆(%)和添加污泥添加剂的钢筋混凝土(%)的实用值。Dunaliella-degree固定5天。(%);加拿大elodaca -在暴露(ext.)时对长度生长的抑制程度(% to control)和水蚤-暴露48天的存活率(%)。提出了建筑材料生产的实用方案和最佳价值，并对生物试验产品(加泥瓷砖和其他含泥废料的产品)的初步应用进行了验证。

Membrane bioreactor (MBR) technology, the practical application of which is growing steadily, is a combination of classical technology of biological treatment with activated sludge with a membrane system of micro- or ultrafiltration. MBR are an alternative to the widely used method of separating activated sludge from wastewater in secondary settling tanks used in traditional biological treatment systems. MBR exclude large-scale negative consequences, as in system with traditional aeration tanks and secondary settling tanks in the "swelling of activated sludge". But "swelling of activated sludge" can affect the nitrification process and minimize the efficiency of ammonium nitrogen removal. The purpose of the work is to study the swelling of activated sludge swelling on the existing membrane bioreactor. The research was carried out by hydrochemical analysis of wastewater in MBR and determination of technological properties of activated sludge in the bioreactor. The negative effect of activated sludge swelling in MBR on nitrification activity in the system was established, which caused a decrease in the efficiency of ammonium nitrogen removal. Filamentous bacteria were identified according to the classification of D. Eickelbum, which caused swelling of activated sludge in the studied MBR, Type 021N.
