Problems solved by technology

It is mainly used to completely decompose sulfides, mercaptans and amines in fermentation excreta, but its application range is narrow, and it is only suitable for pollutants in excrement. The stability is not strong enough, and vacuum packaging is required and light-proof , the storage time is not long enough

Abstract

The invention discloses a biological enzyme deodorant. The biological enzyme deodorant is prepared from an enzyme and a buffering protection system, wherein the enzyme is selected from one or more of proteinase, amylase and lipase; the activity of the proteinase, the amylase and the lipase is more than 1000U / mL (when the enzyme is a liquid preparation) or 1000U / g (when the enzyme is a solid preparation) respectively; the buffering protection system comprises a protection agent and a buffering solution; the protection agent is molasses; the buffering solution is a lactic acid-sodium lactate buffering solution or a citric acid-sodium citrate buffering solution and the pH (Potential of Hydrogen) value is 3.0 to 6.6. Correspondingly, the invention further discloses a preparation method of the biological enzyme deodorant. The biological enzyme deodorant has the advantages of simple formula, low cost, high odor removing efficiency, wide application, high stability, and long storage time, and the requirements on environment conditions in a utilization process are not strict.

Description

technical field [0001] The invention relates to the field of biological preparations, in particular to a biological enzyme deodorant and a preparation method thereof. Background technique [0002] According to the definition of odor pollutants in GB 14554, all gaseous substances that stimulate the olfactory organs to cause people's unpleasantness and damage the living environment are called odor pollutants. The "Basic Environmental Law" defines seven phenomena as "public nuisances", including air pollution, stench, noise, water pollution, vibration, soil pollution and ground subsidence, collectively referred to as the "seven typical public nuisances". Stench is listed as one of the seven typical public hazards. Malodorous gases mainly come from sewage treatment plants, landfills, livestock and poultry farms, etc., or are generated during sludge treatment. Although there are many kinds of odor pollutants, they can be divided into three categories, namely, sulfur (S)-based c...
