preparation example Construction

[0030] The preparation method of the solid fuel derived from the sludge waste bacteria rod comprises the following steps:

[0031] Step S1: raw material pretreatment: Squeeze the sludge with a water content of 60% to 90% to remove water, and use a pulverizer to pulverize the dried waste bacteria sticks to a diameter of less than 30mm;

[0032] Step S2: Mixing treatment of raw materials: first place the sludge and waste bacteria stick powder in the solid fuel manufacturing equipment and mix them evenly, and at the same time continuously add oxidant, sulfur fixing agent, bentonite, mercury fixing agent and The adhesive continues to stir until the material is evenly stirred, and the water content is controlled to be 10%-15%;

[0033] Step S3: cold press forming: the stirred mixture enters the honeycomb forming plate under the solid fuel manufacturing equipment to form a honeycomb solid fuel.

[0034] Please refer to Figure 1 to Figure 11 , the solid fuel manufacturing equipmen...

Abstract

The object of the present invention is to provide a solid fuel derived from sludge waste bacteria sticks, which is characterized in that: it is composed of the following raw materials in mass percentage: sludge 10%-50%, waste bacteria sticks 30%-80%, oxidant 1%- 10%, sulfur-fixing agent 3%-8%, bentonite 0.2%-1%, mercury-fixing agent 3%-8%, adhesive 0.1%-0.5%; the invention realizes the harmlessness of sludge and waste bacteria sticks processing to realize the utilization of resources.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of solid waste resources, in particular to a solid fuel derived from sludge waste bacteria sticks and a preparation method thereof. Background technique [0002] Sludge is an inevitable product of urban domestic sewage treatment. It contains perishable organic substances, and some of them also contain pathogenic bacteria, drug residues and even toxic and harmful heavy metals. With the continuous increase in the amount of urban sewage treatment, the problem of sludge treatment from sewage treatment has become increasingly prominent. [0003] Traditional disposal methods include ocean disposal, landfill, composting, and incineration, but all of them have the risk of secondary pollution; at this stage, the relatively mature technology for sludge treatment is incineration, but due to the high moisture content of sludge, it is not easy to burn. , low heat production, serious pollution, complex...
