Energy-saving sludge drying equipment

Abstract

The invention discloses energy-saving sludge drying equipment, and belongs to the field of sludge drying equipment. The energy-saving sludge drying equipment comprises a sludge feeding pipe, a dryingbox, a cover plate, a bottom support and a water outlet pipeline, wherein the sludge feeding pipe is arranged on the side surface of the drying box in a penetrating manner; the cover plate is mountedon the top surface of the drying box in a screwed manner; the water outlet pipeline is mounted on the outer side of the lower portion of the bottom support in a penetrating manner; and the bottom support is integrally connected with slots surrounding the bottom of the drying box. The energy-saving sludge drying equipment is characterized by further comprising a filter cloth bag, an aeration deviceand a solar water circulation heating device. According to the energy-saving sludge drying equipment, the sludge can be dried in situ, the problem of difficulty in treatment of excess sludge generated by rural sewage treatment is solved, in combination with the characteristics of small amount and scattered distribution of excess sludge generated by a rural sewage treatment device, solar hot watercirculation heating, filter cloth bag microfiltration and aerobic digestion are coupled, and the energy-saving sludge drying equipment is suitable for treating the excess sludge generated by the rural sewage treatment device, and has the advantages of low cost, high efficiency, simplicity and high universality.

Description

technical field [0001] The invention relates to the field of sludge drying equipment, in particular to an energy-saving sludge drying equipment. Background technique [0002] With the increasing emphasis on rural environmental problems in our country, rural sewage treatment has become increasingly important and has become the focus of environmental protection work at present and in the future. Rural sewage is characterized by a wide range of pollution, large fluctuations in water quality and quantity, scattered distribution, and difficulty in collection. However, sewage has good biochemical properties and is suitable for biological treatment. Various small rural sewage treatment devices based on activated sludge method and biofilm method have the advantages of small footprint, low investment cost, and simple operation and maintenance, and have become the mainstream process of rural sewage treatment. However, during the operation of rural sewage treatment plants, excess slud...
