Problems solved by technology
[0002] There are three traditional sludge treatment methods: incineration and landfill and resource utilization. Incineration technology is mostly used in China, but the investment is huge and it is easy to cause air pollution; landfill is mostly used in China, but it needs to occupy a lot of land and will cause environmental damage. Secondary pollution; some large and medium-sized cities in China have very few land regeneration resources, and it is difficult to adopt this method for a long time

The invention discloses a sludge fermentation fertilizer making system and a sludge fermentation fertilizer making method thereof. The system comprises a sludge conveying system, a sludge concentration and digestion system and a fermentation composting chamber, the sludge conveying system comprises a material receiving bin; the material receiving bin is connected to a material inlet of the greenhouse through a material outlet of the spiral feeder; the greenhouse is a conical top type sunlight plate greenhouse, the greenhouse is connected with the anaerobic digester through a mud pump, the anaerobic digester is located below the greenhouse, and a mud outlet of the anaerobic digester is connected with the fermentation composting chamber through a mud pump. The method for evaporating and concentrating the sludge in the greenhouse is adopted, the solar heat collection water tank is used for supplying heat, solar energy is used as main energy, and energy consumption is reduced; the internal circulation device is arranged to realize full contact of anaerobic bacteria and harmful organic matters through internal circulation of digestive juice, heat is transferred through the digestive juice, and a high-temperature environment of anaerobic digestion is ensured. Therefore, the organic fertilizer is prepared by matching the sludge with the combined materials and fermenting, so that the sludge is recycled.
Description
technical field [0001] The invention relates to the field of sludge treatment, in particular to a sludge fermentation fertilizer system and a sludge fermentation fertilizer method. Background technique [0002] There are three traditional sludge treatment methods: incineration and landfill and resource utilization. Incineration technology is mostly used in China, but the investment is huge and it is easy to cause air pollution; landfill is mostly used in China, but it needs to occupy a lot of land and will cause environmental damage. Secondary pollution; some large and medium-sized cities in China have very few land regeneration resources, and it is difficult to adopt this method for a long time. Manufacture fertilizer by legal effect can produce significant economic and environmental benefits. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a sludge fermentation fertilizer...
