TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The auxiliary material comprises the waste materials of the waste fungus dreg obtained by planting the edible fungi and fungus rod. The fermenting strain is the compound microorganism lyophilized strain, which contains independently developed water purifying strain; the nutrient substance needed for activating lyophilized strain comprises peptone, yeast powder, yeast extract, beef extract, brown sugar, glucose, starch, lactose, copper, iron, zinc, manganese, calcium, molybdenum, sodium, potassium salt, citric acid, lactic acid, acetic acid, sodium hydroxide, potassium hydroxide and/or phosphoric acid buffering salt and it also comprises selective antibacterial agent. Preferred Method: The main material and auxiliary material are mixed in the ratio of 50-80% and are pre-wetted by spraying 1.5 times of clean water in an agitator when agitating. Activating lyophilized bacteria, comprising: mixing the lyophilized microorganism strain and nutrient substance in the weight ratio of 1-10 and 1-100000; adding 20 times of water to agitate uniformly; controlling the temperature of the environment at 15-40 degrees C and sealing a drying part using a cover; naturally activating for 2-3 days to prepare active strain liquid; and preparing the liquid and using it. The concentration of the active bacteria is 30-40 hundred million/ml. The added water is portable water and does not contain disinfectant, bactericide, antibiotic and synthetic antibacterial medicine. The temperature of water cannot exceed 45 degrees C and is better to 25-37 degrees C. The container must be cleaned and has a cover capable of sealing. The container can be used repeatedly after it is disinfected. The activated bacteria liquid can be stored in cool and dry place. Disinfecting fermentation of the water purifying bacteria, comprising: taking activated bacteria, which is 30-40% of the mixed material to spraying after disinfecting in a disinfecting chamber by steam; and then fermenting in the fermenting chamber. The temperature in the fermenting chamber is commonly controlled at 35 degrees C; fermenting for 2-4 days; after the fermentation is finished, cooling the material to room temperature; parching the fermenting material according to the requirements to solid powder finished product; or using sterile water to dilute to liquid finished product and packaging integrally to obtain the finished product microorganism water purifying bacteria agent.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The auxiliary material comprises crop straw powder, excrement, tree branch powder, withered grass powder, wood scrape, cotton seed shell, fruit shell powder, corn flour, bran and lime powder.
