For a long period of time, there has been a tendency of “heavy water and light mud†in the design and operation of wastewater in China. Sludge is not disposed of harmlessly and is disposed of arbitrarily. It is easily landfilled and easily pollutes air, soil, and water sources. This poses a serious threat to human health and environmental safety. Sludge is known as an “environmental killer,†and as of the end of 2010, sewage treatment in cities and towns nationwide. The volume is 34.3 billion cubic meters, which is equivalent to the total capacity of a Three Gorges Reservoir. And this “reservoir†emits nearly 22 million tons of “dehydrated sludge†every year, of which 80% of sludge is not treated. How to deal with the sludge has become a major problem in urban life. How to properly treat the sludge? We can try to ferment the sludge into organic fertilizer with Jinpo Sludge Fermenting Agent, which can not only reduce the urban pollution and recycle the waste, but can also be used to fertilize the farmland and improve the quality of agricultural products. Let's briefly talk about the method of fermenting sludge into organic fertilizer:
1. Preparation of materials: sludge, straw powder or mushroom residue, litter, etc., Jinbao sludge fermentation agent.
2. Material formula: The main material is sludge, add 20% to 30% of mushroom residue. No mushroom slag can be replaced with straw powder, litter, rice husks, etc.
3 steps:
1 Dilution strains: 1kg goldfish starter can ferment sludge mixture 4 to 5 tons. First, strains and 5 ~ 10kg corn flour or bran, rice bran, etc. without water evenly diluted with dry, waiting for use.
2 Mixing: First mix the sludge and mushroom slag uniformly. After mixing the sludge and mushroom residue mixture, mix the mixed bacteria and adjust the appropriate moisture. If it is dry, sprinkle it with water. Pay attention to the water content of raw materials must be controlled at 55% to 65%, judging the method of water: grab a handful of material, see the watermark but not drip, landing can be dispersed (water slow fermentation, poor water ventilation, but also Causes "corrupt bacteria" work to produce odors).
3 Construction of heaps: Fermentation reactors are generally 1.5 meters high and 2 meters wide with a total volume of not less than 3 cubic meters. After the construction is completed, the air-permeable cover shall be covered on the pile and shall be shaded and protected from rain.

4Maintenance: After the start of the fermentation process, the temperature can rise to 50-60°C for 48 hours, and reach 70°C or more on the third day. In this high temperature, it should be turned over 2 or 3 times to stabilize the temperature at 55～ At 65°C, basically completed in about 10 days. During the fermentation process, appropriate water supplements should be taken depending on the circumstances. After fermentation, all the materials are black or dark brown, soft to the touch, fragile, fermented, and ready to use.
The sludge is made into bio-organic fertilizer by utilizing the biodegradable sludge, which has the advantages of fast fermentation, good fermentation, complete fermentation, and no burning of seedlings. Both high-temperature fermentation, low-temperature fermentation, greatly shorten the production time, reduce costs and other characteristics, the application is extremely wide.
