METHOD FOR PREPARING REAGENT FOR DETOXIFYING CLEANSING CONSTRUCTION DEPOSITS AND METHOD FOR DETOXIFYING CLEANSING CONSTRUCTION DEPOSITS Russian patent published in 2006 - IPC C08H1/06 C07C227/28 C02F11/00 

FIELD: ecology, chemical technology.

SUBSTANCE: invention proposes a method for preparing a reagent used in detoxification of deposits in cleansing constructions. Method involves an aqueous-thermal treatment of waste comprising animal proteins in the presence of alkali. Waste, water and alkali are taken in the ratio = 1:(1.8-2.0):(0.38-0.46), respectively, and treatment is carried out at temperature 160-180°C for 25-30 min to obtain the end product consisting of an alkali solution and mixture of sodium or potassium hydrate salts of amino acids. For treatment of cleansing sewage water deposits the measurement of the necessary amount of reagent is carried out with taking account the concentration of each heavy metal as a component of the deposit. Method provides preparing the effective agent for detoxifying the cleansing construction deposits and reducing the consumption of reagent in carrying out the detoxification of deposits of cleansing constructions.

EFFECT: improved preparing method, enhanced effectiveness of detoxification.
