Problems solved by technology

Traditional conditioners mainly include straw, rice husk, leaves and wood chips, etc. The above-mentioned conditioners have no obvious effect on improving the pile structure, and the dosage is large, so it is difficult to recycle, and their components are cellulose, hemicellulose, Refractory substances such as lignin are mainly degraded slowly in the later stage of composting, prolonging the period of sludge composting, thereby increasing the cost of sludge composting

Embodiment 1

[0026] A method for treating compost conditioners with high-pressure blasting technology to improve their physical properties, including the steps of raw material processing, blasting treatment, and application in composting, the specific steps are as follows:

[0027] (1) Process the raw material into a 1-2cm square conditioner;

[0028] (2) Put the conditioning agent into the blasting reaction kettle, start the blasting machine, control the reaction pressure to 3amt, hold the pressure for 30-60s, blast the time for 0.005-0.02s, and then blast;

[0029] (3) Apply the blasting conditioner and the remaining sludge to the compost at a ratio of 1:3, and observe its water absorption performance. After the composting is completed, the conditioner is screened out and placed in a cool place to measure its water loss performance. The interval is 24h.

Embodiment 2

[0031] A method for treating compost conditioners with high-pressure blasting technology to improve their physical properties, comprising the steps of preparation of raw materials, processing of raw materials, blasting treatment, application in composting, etc. The specific steps are as follows:

[0032] (1) Process the raw material into a 1-2cm square conditioner;

[0033] (2) Put the conditioning agent into the high-pressure reactor, start the high-pressure blasting machine, control the reaction pressure to 4amt, hold the pressure for 30-60s, blast the time for 0.005-0.02s, and then blast;

[0034] (3) Apply the blasting conditioner and the remaining sludge to the compost at a ratio of 1:3, and observe its water absorption performance.

Abstract

The invention discloses a method for treating a compost conditioner by blasting technology to improve its physical and chemical properties. The specific steps are as follows: processing woody raw materials into a conditioner with the same particle size and shape of 1-3 cm; performing blasting treatment in a blasting reaction kettle , the bursting pressure is 3-8atm, the holding time is 30-60s, and the blasting time is 0.005-0.020s; apply the pretreated conditioner to the sludge compost, measure its water absorption performance, and sieve the conditioner after composting Store in a cool, unventilated place to measure its water loss performance. The invention adopts the blasting technology to process the conditioner, which requires simple equipment and simple process, and effectively improves the physical and chemical properties of the conditioner: the porosity is increased, the air permeability is improved, the rate of water absorption and dehydration is increased, and the circulation of the conditioner is accelerated. Utilization process, in summary, the blasting-treated conditioner has far-reaching social significance and economic value in the composting process.

Description

technical field [0001] The invention relates to the technical field of physical and chemical modification of sludge composting conditioners, in particular to a method for treating sludge composting conditioners with blasting technology to improve their physical and chemical properties. Background technique [0002] In the high-temperature aerobic sludge composting, the conditioner can adjust the material w(C) / w(N) ratio, moisture content and ventilation, and is an important auxiliary material in the sludge composting process. Traditional conditioners mainly include straw, rice husk, leaves and wood chips, etc. The above-mentioned conditioners have no obvious effect on improving the pile structure, and the dosage is large, so it is difficult to recycle, and their components are cellulose, hemicellulose, Refractory substances such as lignin are mainly slowly degraded in the later stage of composting, prolonging the period of sludge composting, thereby increasing the cost of sl...
