Problems solved by technology

[0004] However, when using composting technology to compost sludge with high water content, we have been facing a very urgent problem, that is, sludge with high water content cannot be granulated, and some organic matter with low water content must be mixed in the sludge to reduce pollution. The moisture content of the mud is convenient for sludge granulation, but the cost is high and the treatment is not convenient enough

Embodiment

[0028] In this embodiment, a treatment method of solar sludge drying combined with sludge composting is shown, combining figure 1 As shown, it mainly includes the following steps, that is, entering the mud - turning and throwing - back mixing - drying - adding other organic waste - fermenting and composting - exiting material.

[0029] First of all, sludge feeding, turning and throwing, back-mixing, and drying are the complete drying process in the sludge drying and granulation area. The sludge with a moisture content of about 80% is sent to the solar sludge drying greenhouse by the conveying device , the sludge is continuously turned and moved forward under the action of the turning and throwing machine. A dehumidification fan is arranged in the solar sludge greenhouse, and the water in the sludge is continuously evaporated under the action of the dehumidification fan and the greenhouse effect, and the moisture content is continuously reduced. At the same time, the sludge ca...

Abstract

The invention relates to the technical field of sludge treatment, in particular to a solar sludge drying and sludge composting combined treatment method and equipment, wherein the method comprises thefollowing steps: S1, pre-drying sludge by a solar sludge drying method; S2, carrying out compost fermentation is conducted on the dried sludge; preferably, after the step S1, the method further comprises the steps of S1.1, adding organic matter with the water content higher than that of the pre-dried sludge is added, and continuously drying the sludge through a solar sludge drying method. Compared with the prior art, solar sludge drying and sludge composting are combined, the sludge treatment method which is more economical, convenient and easy to implement is achieved; low-cost solar sludgedrying and sludge composting are combined into one greenhouse, the investment cost is saved, and the operation cost is reduced, and thereby a good treatment channel is provided for urban organic garbage; in addition, different working sections are ingeniously and reasonably reinforced by utilizing different functional sections of the solar drying greenhouse.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a treatment method and equipment for solar sludge drying combined with sludge composting. Background technique [0002] Solar sludge drying refers to the use of solar energy as the main energy source to dry sludge. This process is applied to the field of sludge treatment with the help of traditional greenhouse drying technology combined with contemporary automation control technology. The main purpose is to use solar energy, a clean energy, as the main energy source for sludge drying. Compared with the traditional thermal drying technology, the solar sludge treatment and drying technology has the advantages of low energy consumption, low operation and management costs, stable and safe system operation, low temperature, and small dust generation. The main source of energy can meet the needs of sustainable development. [0003] Sludge composting is the process of mixing ...
