specific Embodiment approach

[0007] The specific embodiment of product of the present invention is:

[0008] 1. Pretreatment of main materials and auxiliary materials:

[0009] Main material pretreatment: gather the discarded mushroom sticks after planting edible fungi to the fermentation site, manually remove the outer plastic bag, take out the waste fungus residue, crush it with a crusher, and stack it in the fermentation site.

[0010] Pretreatment of auxiliary materials: The auxiliary materials can be selected from straw powder, feces, twigs, hay powder, wood chips, cottonseed hulls, fruit shell powder, cornmeal, bran, and lime powder according to the situation, and mix them evenly.

[0011] 2. Mixing treatment:

[0012] According to the ratio of the proportion of the main material to 50%-80%, mix the pretreated main material and auxiliary materials, send them into the mixer and mix them evenly. pre-wet.

[0013] 3. Preparation of water purification bacteria solution:

[0014] The water purificati...

Embodiment 1

[0023] Embodiment 1: Take 1000 bags of discarded mushroom sticks after the primary cultivation of Jade mushroom, manually remove the plastic outer film, and crush the waste residue, about 100 kg. Take 40 kg of cornmeal, 30 kg of bran, and 10 kg of excrement. After mixing and stirring evenly, add 200 kg of water for mixing. After sterilization, after activation of the freeze-dried composite water purification bacteria, take 100 kg of direct spray inoculation, ferment in a fermentation chamber at 35°C for 3 days, cool and dry, and then pack the solid microbial water purification bacteria for use.

Embodiment 2

[0024] Embodiment 2: Get each 1000 bags of discarded bacterium sticks of Pleurotus eryngii and Pleurotus eryngii once cultivated, manually remove the plastic outer film, and pulverize the waste residue, about 200 kilograms. Take 60 kg of sawdust powder, 50 kg of cottonseed hulls, and 20 kg of bran. After mixing and stirring evenly, add about 350 kg of water for mixing. After sterilizing, activate the freeze-dried composite water purification bacteria, take 200 kg of bacteria liquid to spray and inoculate directly, ferment in the fermentation chamber at 35°C for 3 days, cool and dry, and repackage the solid microbial water purification bacteria agent for use .

Abstract

In recent years, with the rapid growth of the traditional edible fungus industry all over China, the pollution and the hazard generated to the entironment and the edible fungus industry per se by a large number of obsolete fungus sticks (slags) after the primary planting of edible fungi also become bigger and bigger, and the innocent treatment and the research development in the aspect of reutilization of the obsolete fungus sticks in the industry also become more and more, wherein the research of preparing the water purifying microbial inoculum by taking the obsolete fungus sticks as the main materials is an important research direction. The invention provides a method taking the obsolete fungus sticks after the edible fungi are planted as the main materials to ferment water purifying bacteria to prepare the water purification agent. In the invention, the obsolete fungus sticks and the fungus slags of the edible fungi are used as the main materials, wherein the weight proportion is higher than 50 percent, and then the main materials cooperate with other auxiliary materials, wherein the auxiliary material mixture ratio is simple and varied; then independently developed compound water purifying freeze-drying strains are adopted to be fermented, and thereby, the water purifying bacterium is prepared. The invention reduces the preparation cost, realizes the deep development and utilization of wastes, also reduces the pollution to the entironment and eliminates the pollution of the edible fungus planting industry. The invention can realize use and preparation and has simple operation, low cost, high product activity and good water purification effect.

Description

technical field [0001] The invention relates to the field of comprehensive development and deep utilization of waste, in particular to a method for preparing water-purifying bacteria by using waste fungus slag after cultivation of edible fungi as a main ingredient. technical background [0002] In recent years, with the rapid rise of the traditional fungus industry in various parts of my country, a large number of discarded mushroom sticks (slag) after one planting of edible fungi have become more and more polluting and harmful to the ecological environment and the edible fungus industry itself. There are more and more researches in the industry on the harmless treatment and secondary utilization of waste bacterial sticks. Among them, the research on the preparation of water purifying bacteria agent with waste bacteria sticks as the main material is an important research direction. At present, domestically, there is no mature technology for preparing water purifying bacteria...
