The year 2015 is the year of China's environmental protection, and environmental protection has already mentioned the height of China's national strategy. Local governments in all provinces have signed the order of the environmental protection force to the central government. Beijingâ€™s leaders have even stated to the Politburo that â€œpolluting the pollution is not enough. "To see", Henan governor also put it bluntly that "Henan, more than 100 million people living environment can not be solved, and what to use GDP," is very encouraging, but the light is determined not yet have to use technology, use the smallest The most cost-effective way to solve the actual sources of pollution around, in many of our pollution, sludge is one of the key pollution issues that we must mention. Sludge is a by-product of sewage treatment plants. Nearly a third of the organic matter in the wastewater is converted into sludge. There are more than 20 million tons of pollution in China each year, and 80% of them have not been properly handled. The actual construction of sludge treatment and disposal facilities is still very slow. At present, most of the country's sludge has not been stabilized and treated in a harmless manner. Most of the sludge is sent to urban garbage treatment plants for simple landfill, and even simply stacked in the open air, causing great harm to the environment. The upper sludge has two properties. On the positive side, the sludge contains nutrients such as nitrogen and phosphorus. The bad part is the presence of heavy metals, germs, etc. If not handled properly, it will destroy crops and the ecological environment. As long as it is properly handled, it can still be used in a large amount to make fertilizer in the land. The Jinpo Sludge Fermenting Agent that realizes the recycling of waste in this respect has a very good processing function and a large number of actual combat effects. The method of operation
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 50-60Â°C for 48 hours, and reach 70Â°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 55ï½ž At 65Â°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, to achieve the use of sludge waste, reduce hazards, for the country's environmental protection problems, and contribute to the improvement of the living status of the people.
