Problems solved by technology

However, direct incineration of sludge is still a high-energy-consuming disposal method, which is not in line with energy-saving benefits, nor is it a sustainable energy model.
Therefore, sludge dehydration and incineration is a method commonly used in foreign countries, and it is also a sludge treatment process encouraged to be promoted in my country. It is a necessary step in the sludge disposal strategy. However, there is a big disadvantage of the existing sludge dehydration technology, which is the investment in treatment facilities. Large and expensive to process

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 The manufacture method of shown sludge biomass fuel, it may further comprise the steps:

[0024] Step 1. Pretreatment of water-containing sludge: According to the nature and treatment method of sludge, water-containing sludge is divided into inorganic water-containing sludge and organic matter water-containing sludge as the basis for subsequent treatment; generally, biochemical methods are used to treat water-containing sludge Most of the domestic sludge is organic sludge, which can be used as fuel; while a considerable part of the industrial sludge treated with acid and alkali is inorganic sludge. This kind of industrial sludge is simply squeezed and the pH is adjusted to 6-7. It can also be classified as organic hydrous sludge, waiting for subsequent treatment;

[0025] Step 2. Remove impurities in the organic water...

Abstract

The invention relates to a manufacturing method of sludge biomass fuel. According to the method, organic materials containing water sludge and biomass raw materials are mixed and then subjected to fermentation and dehydration to manufacture the new sludge biomass fuel. The method for treating the sludge is economical, practical and high in treatment capacity, and by means of the method, the sludge biomass fuel can be manufactured. By means of the method, environment-friendly treatment of urban sludge is achieved, resource recycling is achieved, non-renewable resources are reasonably replenished, a novel energy material which is the sludge biomass fuel is developed, the sludge biomass fuel can replace natural coal, the calorific value of the sludge biomass fuel is 1500-5000 kilocalorie, the sludge biomass fuel is easy to burn, and the emission of the sludge biomass fuel is lower than emission standards of European Union. Ashes obtained by burning of the sludge biomass fuel are rich in elements of calcium, magnesium, phosphorus, potassium and sodium so that the ashes are superior warm readily available organic fertilizers, and the problem that the urban sludge can not be directly returned to fields is solved.

Description

technical field [0001] The invention relates to a method for manufacturing sludge biomass fuel. Background technique [0002] With the development of my country's industrial and urbanization process and the improvement of sewage treatment rate, the amount of sludge produced will also increase. However, urban sludge has great harm to the living environment of human beings. Judging from the current situation of sludge treatment in my country, the domestic sludge treatment technology is still relatively backward, and the sludge treatment rate is still relatively low. It is necessary to strengthen the development of sludge treatment industry to meet the needs of the environment. protection needs. [0003] Common disposal techniques for sludge include: agricultural use, composting, landfill, and incineration. Among them, the harmless incineration method of sludge has been valued by more and more developed countries. It is the most thorough treatment method for sludge. Compared w...
