RU2159115C1 - Method of preparing curative mud from clayey halurgical sludges - Google Patents

Abstract

FIELD: mining industry. SUBSTANCE: sludge taken from sludge depository is placed into sealed vessel wherein constant level of water preventing drying of clay is maintained. To contents of vessel, desulfatization bacteria are then added in amount sufficient to reduce sulfates present in mud into hydrogen sulfide. EFFECT: disposed potash production waste.

Description

 The invention relates to the field of integrated mining and chemical mining and processing of sylvinite in a galurgic manner and can be used to obtain therapeutic mud.

 Over the decades of operation of the Verkhnekamsk potassium salt deposit in the sludge storage facilities, significant reserves of clay-salt sludge, which are waste products of potash production, have been accumulated. Sludge contains useful components, however, no method has yet been developed for the disposal of these sludges [1].

 Clay-salt sludge in composition refers to sulfide silt mud, which is one of the main types of therapeutic mud [2, p. 205].

 In terms of sulphide content, the mud from the sludge storage facility is classified as weakly sulphide, in terms of mineralization of the mud solution it is very highly mineralized, in the composition of the mud solution it is sodium chloride and, at the place of formation, marine. [2, p. 205].

The origin of silt mud is associated with the vital activity of microorganisms, as a result of which biologically active substances (enzymes, hormones) accumulate, colloids and gases (H ₂ S) are formed [3].

 Biochemical processes of sulfate reduction involved in the formation of silt sulfide mud occur under strictly anaerobic conditions in the presence of easily digestible organic substances, soluble sulfates and the corresponding microflora.

The results of a chemical analysis of the pulp supplied to the sludge store from the galurgic factory indicate the presence of significant amounts of sulfates in the mud solution (insoluble residue 26.48%, KCl 12.88%, NaCl 16.19%, MgCl ₂ 0.37%, CaSO ₄ 4.87%, CaCl ₂ 0.05%, Br 0.076%, H ₂ O 39.19%).

 It was established (Yu. A. Tretyakov. Study of the material composition of insoluble salt residues in industrial strata of the southern part of the Verkhnekamsk deposit. UV VNIIG, 1973, 63 pp.) That the main components of the insoluble residue are hydromica (50-70%), carbonates (10-30 %), sulfates (10-20%) and organic (carbonaceous) substance (10%). The content of the sludge fraction (particle size less than 0.01 mm) is 74.7-97.4%.

 A known method of obtaining therapeutic mud from silts of salt lakes [2, p. 212 - 213).

 The disadvantage of this method is that to obtain therapeutic mud is not provided for the use of industrial waste.

The invention has no analogues /
The objective of the invention is the use of potash waste to obtain therapeutic mud.

 The problem is solved by the fact that they produce sludge from sludge storages, then place them in an airtight container in which a constant water level is maintained, preventing clay from drying out. After that, desulphating bacteria are added to the artificial mud.

 In existing sources of information such a method of obtaining therapeutic mud is not found.

 The method is as follows.

 A sample is taken from the storage of clay-salt sludge of the galurgic factory using a dipstick or drill bit. Then carry out a study of the physico-chemical properties of the mud. Separately, a mud solution, a skeleton or a crystalline skeleton, a colloidal complex are studied. A sanitary-bacteriological study of mud is carried out. Based on the content of sulfates in it, the necessary amount of desulfatizing bacteria necessary for the reduction of sulfates to hydrogen sulfide is calculated, which in turn, as a result of interaction with iron salts, turns into colloidal sulfur dioxide, which is involved in the formation of dirt.

 Then, by known methods, mud is extracted from the sludge store and delivered to a mud bath. Next, the dirt is placed in a sealed container in which a constant water level is maintained, which prevents the drying of sludge. After that, the calculated amount of desulfatizing bacteria is added to the tank to reduce sulfates to hydrogen sulfide. After the biochemical desulfatization process is over, mud is used to treat various diseases. The resulting mud in its composition refers to sulphide silt mud, which is one of the main types of therapeutic mud. With their help, they treat some diseases of the joints, muscles, bones, nervous system, the effects of thrombophlebitis, inflammation of the serous cover of the abdominal cavity, skin diseases, female diseases, chronic prostatitis, etc.
