USING OF WASTE OF A CHEMICAL PLANTS FOR SOLVING ENVIRONMENTAL 
PROTECTION 
Abstract: In the work for fixing salted sand the dried bottom of the Aral Sea and treating 
industrial process wastewater used waste Chemical Plants of a Republic Uzbekistan— distilled 
liquid contained in the composition of 11–12% of calcium chloride. At using this waste as a part 
of the fixing agent in the process of fixing the salted sand established creation surface crust that 
has a sufficiently high magnitude strength of the order 2,4–3,02MPa and content of water-stable 
aggregates in the structure equal to 6.28% vs. 69,91–77,2% of the original sand, in addition using 
of this waste show that at the purification of industrial waste water of the textile industry water is 
purified from dyes to 94–98%.

Relevance 
The environmental situation in the 
Republic of Uzbekistan strongly put a question 
about carried out works intended on fastening 
salted sands of the dried bottom of the Aral Sea 
with cheap, non-toxic and available reagents-
fixers as well as increasing the degree of 
sewage treatment of various production of 
republic 
by 
import-substituting 
local 
adsorbents and reagents [1; 2]. Earlier, we in 
[3; 4], proposed particular types of reagents in 
order to create artificial structures tested by 
cheap industrial wasts and polymers. Fixing 
sand of coast of the Aral Sea region 
Kazakhdarya using complex addition of 
reagents and industrial wasts will contribute to 
the establishment of a small thicknesses of 
sand durable waterproof structure. The most 
difficult problem in terms of technology and 
also includes cleaning colored textile industry 
waste water, due to the huge volume of this 
water and a wide, ever- changing range of used 
dyes. It should be noted that so far no highly 
effective

wastewater of textile industries. It is known 
that the chemical industry, in particular, 
Kokand chemical Plant, has a number of 
wastes used as secondary raw materials in the 
different branches of national economy. Such 
wastes have been used by us as a component 
of the reagent process purification dyed 
wastewater of textile industry [2]. Aim of this 
work — the development of methods of fixing
