The previous paper contains the data concerning the decreasing of formaldehyde concentrations in waters of furniture making enterprises. The formaldehyde concentration varies from 0,1 up to 10 r/dm\ The chemical and adsorptive ways are used. The clay mineral with the layered structure of montmorillonite is chosen as an adsorbent. The purification efficiency in chemical way is 95%, in adsorptive way - 98%. The adsorbent utilization of heavy emulsive fractions, of oligomer fractions and of cleared parts of foul water was considered in this paper. A neutralized from the formaldehyde adsorbent was put into a small-toxic plaster solutions and this procedure resulted in the increasing of composition strength in 1,5 times and in the decreasing of volume weight up to 10 %, i.e. in the thermal characteristics improvements. Pitch emulsion of foul water was used for manufacturing of heat-insulated solutions as a heat-insulated layer in roof and floor making. The abovepitched water, which is without formaldehyde, was tested in vegetation - in processing sunflower in summer period. As a result the seed multitude increased, raw oil in sunflower seeds increased as well. The technological scheme of glue application made on the basis of carbamidoformaldehyde pitch emulsion with the closed loop system of water supply is developed in this paper. The general ecological and economic capacity and total economic benefit of clearing and utilization waters are calculated. Nature protecting technologies have patents and introduced on furniture and building enterprises.
