System for soil fertilization-increasing-type remediation and remedying method thereof

Abstract

The invention discloses a system for soil fertilization-increasing-type remediation. The system comprises coaxial upper cylindrical box and lower cylindrical box which are integrated upwards and downwards. The lower side of the interior of the lower cylindrical box is provided with a soil taking cavity. The interior of the upper cylindrical box is coaxially provided with a sludge heat-preserving cone cavity. An upper end of the soil taking cavity is communicated with a lower end of the sludge heat-preserving cone cavity through a coaxial cylindrical channel. The coaxial cylindrical channel isinternally coaxially provided with a conveying cylinder. An outer wall of the conveying cylinder is fixedly connected with an inner wall of the cylindrical channel through a support rod. The system iscapable of enabling sludge at the bottom of a lake after sterilization to be mixed with desertification poor fertilization soil, thereby achieving the effect of remedying the soil. A structure of a steam generating cavity is additionally installed. Ethyl alcohol steam is continuously generated in the steam generating cavity, the ethyl alcohol steam can effectively replace traditional fuel gas supply, and renewable energy sources can be utilized well.

Description

technical field [0001] The invention belongs to the field of soil restoration. Background technique [0002] Too much silt at the bottom of rivers and lakes can easily cause problems such as river bed elevation and water odor. The silt at the bottom of the lake contains a large amount of organic fertilizer components, but the silt contains a large number of microorganisms and bacteria, and it is easy to cause infection, burn seedlings, and corrode crops when used directly for planting. The water content of the sludge is very high, and the existing technology is to completely disinfect and remove the water in the sludge through high-temperature dehydration, and then use it; this dehydration process consumes energy; [0003] The present invention adopts the method of non-dehydration, directly heats up the sludge rapidly, maintains the sterilization temperature for a certain period of time, and then mixes the sterilized sludge with high water content and sandy soil with low wat...
