Problems solved by technology

[0004] After the dehydration treatment of the existing rural ditch sludge, the compounds in the chemical conditioner will remain in the dewatered sludge. These dehydrated sludge will easily cause unpredictable environmental impacts in the subsequent environmental utilization process. ecological risk
At the same time, the sludge is prone to odor after long-term storage, and the odor cannot be effectively treated during treatment, which is likely to damage the health of the staff
[0005] The sludge dewatering effect of the prior art is poor, and it is very harmful to the environment

Embodiment 1

[0067] The dehydration method of the dehydration equipment 5 provided by the embodiment of the present invention is as follows:

[0068] 1) Adjust the pH of the sludge.

[0069] 2) Lysozyme treatment: adding lysozyme to the sludge after pH adjustment for reaction.

[0070] 3) Dehydrating the sludge reacted with the lysozyme by a dehydrator to obtain a sludge filter cake.

[0071] The step of adjusting the pH of the sludge provided by the present invention specifically includes adding acid or alkali to the sludge until the pH of the sludge is adjusted to 7.0, and then standing for 1 hour.

[0072] The addition amount of lysozyme provided by the invention is 2g / 100g dry sludge.

[0073] The step of lysozyme treatment provided by the present invention specifically includes adding the lysozyme into the sludge after adjusting the pH, stirring evenly, and shaking and reacting at a constant temperature for 2-8 hours.

[0074] According to the present invention, before adding the l...

Embodiment 2

[0076] Carbonization equipment 7 carbonization method that the embodiment of the present invention provides is as follows:

[0077] (1) Sludge deodorization, configure deodorizing bacteria according to the formula, add deodorizing bacteria after the sludge is heated up, stir and let it stand for 5 hours.

[0078] (2) Drying, sending the sludge into the drier to dry to a water content of 88%, then pressing it into a honeycomb shape with a press, and putting it into the drier to continue drying until the water content is 78%.

[0079] (3) Carbonization, the dried sludge is chopped into small pieces, pressurized and sent to the carbonization system, and cooled to room temperature after carbonization is completed.

[0080] (4) Recycling, pressing the carbonized sludge into a net shape, using 4 carbonized sludge nets to overlap to make a simple filter device, passing the sludge in step (1) through the filter device and then performing deodorization .

[0081] (5) Carbonized sludg...

Abstract

The invention belongs to the technical field of treatment of rural ditch sludge, and discloses a treatment method and a treatment system for rural ditch sludge. The treatment system for the rural ditch sludge comprises a water quality detection device, a sludge image collection device, a main control device, a sludge extracting device, a dewatering device, a drying device, a carbonization device and a display device. Lysozyme is used to hydrolyze the cell walls of microorganisms in the sludge through the dewatering device, so the system can achieve a good sludge dewatering effect and has few harms to the environment. The carbonization device utilizes the deodorizing function of the microorganisms and the filtering function of carbonized sludge to effectively remove the odor of the sludge after long-time sludge before drying the sludge, so the health of the worker is prevented from being damaged.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment in rural ditches, and in particular relates to a treatment method and system for sludge in rural ditches. Background technique [0002] Sludge treatment is the process of sludge reduction, stabilization and harmless treatment. The higher the degree of wastewater treatment, the more sludge residues are generated that need to be disposed of. Unless land treatment or sewage ponds are used to treat sewage, general sewage treatment plants must be equipped with sludge treatment facilities. For modern sewage treatment plants, the treatment and disposal of sludge has become the most complex and expensive part of the operation of the sewage treatment system. However, after the dehydration treatment of the existing rural ditch sludge, the compounds in the chemical conditioner will remain in the dewatered sludge, and these dehydrated sludge will easily cause environmental pollution in the subseque...
