Sludge treating machine applied to ecological river and treating method of sludge treating machine

Abstract

The invention mainly discloses a sludge treating machine applied to an ecological river and a treating method of the sludge treating machine. The treating machine comprises a pulverizing bin, a treating bin, a water drainage bin, a drying bin and a storage bin, wherein a feeding hopper is arranged above the pulverizing bin; a pulverizing mechanism is arranged in the pulverizing bin; the treating bin comprises a chemical treating bin and a microbial treating bin; a filter pressing device is arranged in the water drainage bin; the water drainage bin is connected with the drying bin through a material guiding plate; a conveying mechanism and a heating mechanism are arranged in the drying bin; and a discharging opening of the conveying mechanism is connected with the storage bin. The treating method comprises the following steps: sludge digging, pulverizing treatment, chemical treatment, microbial treatment, water drainage treatment, drying treatment and storage. The method is simple and effective, convenient to operate, environmentally friendly, and high in treatment efficiency, the quality of the sludge is improved effectively, toxic and harmful substances in the sludge are reduced, meanwhile, water in the sludge is reduced, storage and conveyance of the sludge are facilitated, and purposes of changing harmful substances into beneficial substances, recycling materials and protecting the environment achieved.

Description

technical field [0001] The invention relates to a sludge processing machine applied to an ecological river course and a processing method thereof. Background technique [0002] A large amount of silt is always being generated on the earth, especially in places where human beings live, where silt exists everywhere, which not only pollutes the environment, but also affects people's daily life. The sludge contains organic matter such as domestic garbage, sewage pits, manure, farmyard manure, bark, leaves, weeds and sawdust. The silt accumulation phenomenon of rivers, rivers, lakes and lakes makes the water bottom level far exceed the land level, which is easy to block the waterway and bring certain adverse effects. According to the survey of relevant departments, the annual collection of silt from domestic lakes and rivers can reach at least 70 million tons, and the total annual collection of silt from urban sewers can exceed 100 million tons. Therefore, how to deal with the ...

Problems solved by technology

[0003] The usual practice is to send the cleared silt directly to the countryside for use as fertilizer. For a long time in our country, farmland crops have been applied chemical fertilizers, and the land is poor. In addition to applying chemical fertilizers and natural organic fertilizers to farmland, it is also difficult to purchase organic fertilizers for farmland. Crop application, even the application of all natural organic fertilizers is negligible to improve the soil environment, and it is difficult to achieve agricultural circular economy

The use of silt can effectively improve soil properties, increase soil fertility, and increase crop yields. However, due to the fact that the silt has not been purified and detoxified, it not only affects the environment, causes secondary pollution, and also loses its use value. In addition, for untreated The storage and transportation of dried sludge is also a big problem. The sludge water contains a large amount of pollutants, which not only takes up a lot of space, but also easily undergoes anaerobic biological reactions spontaneously during stacking, producing odors and leading to sludge dehydration.
