Preparation method of environment-friendly biological air purifying agent for air purification

The invention discloses a preparation method of an environment-friendly biological air purifying agent for air purification. The biological air purifying agent is prepared from the following raw materials in parts by weight: 2 to 4 parts of herba menthae extract, 4 to 6 parts of coenzyme, 2 to 10 parts of active biological enzyme, 1 to 20 parts of amino compound, 5 to 30 parts of deodorant, 1 to 20 parts of polysaccharide, 1 to 8 parts of polypeptide, 1000 to 2000 parts of water, 2 to 10 parts of ultraviolet light absorber and 3 to 10 parts of high-temperature stabilizer, the air purifying agent has the beneficial effects that the high-stability enhancing solution is mixed with the original agent of the air purifying agent, so that the stability of the air purifying agent is improved without changing the biological purification function of the original agent of the air purifying agent, the air purifying agent is not influenced by temperature, humidity and ultraviolet rays, and the durability of the air purify
