Problems solved by technology
Mechanical drying usually requires the addition of chemicals to the sludge, which will increase the amount of sludge and have an adverse effect on subsequent treatment. What's more unfavorable is that mechanical drying usually cannot remove water when using chemicals.

Abstract
The invention provides a biological drying reactor of sludge. The biological drying reactor comprises a reactor main body, a ventilating and exhausting system and an online control and recording system, wherein the reactor main body is formed by a barrel body; the exhausting and exhausting system is provided with an air inlet hole, an air exhausting hole, a rotor flow meter, an air compressor and a time relay; the online control and recording system is a recorder; the outer layer of the barrel body is provided with an insulating layer; a penetrating-liquid discharging port is arranged in the bottom part of the reactor; opposite to the direction of the penetrating-liquid discharging port, an air inlet hole is arranged and is connected with the rotor flow meter which is connected with the air compressor; the air compressor is controlled by the time relay; a perforating plate is arranged in the barrel body and consists of a plurality of aeration holes; the barrel body is internally provided with a temperature sensor which is connected with the recorder. The biological drying reactor provided by the invention has the advantages that the real-time monitoring can be realized, the water-content is greatly reduced, the drying speed is fast and the effect is good.
Description
technical field [0001] The invention belongs to the technical field of environmental protection, and mainly relates to a sludge biological drying reactor. Background technique [0002] With the acceleration of industrialization and urbanization, the volume of sewage treatment in my country is increasing, and the corresponding sludge production is increasing rapidly. The annual sewage treatment volume of the "Twelfth Five-Year Plan" will reach 50 billion cubic meters, and the corresponding annual sludge (80% moisture content) production will be about 40 million tons; by 2020, my country's sludge production is expected to exceed 60 million tons per year . So far, most of the sludge has not been properly treated, and the problem of secondary pollution is prominent. [0003] The sludge after urban domestic sewage treatment generally has a water content of about 80%, is rich in nutrients such as organic matter, and contains a certain amount of heavy metals, viruses, pathogens, p...
