Embodiment

[0024] Experimental equipment: reaction treatment device for direct oxidation of sludge generated by microcurrent 1600×1400×650 (mm), effective volume 0.5L

[0025] DC power supply 20V / 2000A

[0026] Sludge pump N: 0.55kw, Q: 1-5m 3 / h

[0027] Analytical instrument: 10,000-level electronic balance

[0028] infrared oven

[0029] Water circulation vacuum pump

[0030] Sludge source: Changzhou Chengbei Sewage Treatment Plant

[0031] Experimental steps:

[0032] 1. Start the sludge pump and adjust the flow rate to 3m 3 / h, pump the wet sludge into the reactor to the water level of the reactor overflow port, turn off the sludge pump, start the DC power supply, restart the sludge pump, continue to work according to the set flow rate, and take a sample after 10 minutes.

[0033] 3. Adjust the flow meter at the outlet of the sludge pump to adjust the flow to 1.5m 3 / h, sampled after 20 minutes.

[0034] 4. The samples taken are three groups of balanced control sa...

Abstract

The invention relates to a reaction processor for directly oxidizing residual sludge by using micro-currents. According to the invention, microbes, organic pollutants, and viral bacteria in water-containing sludge can be effectively oxidized and decomposed by using a micro-current direct oxidization technology, such that an average removal rate of the microbes, the organic pollutants, and the viral bacteria in the sludge can be above 99%. The residual solids are complexed into metal oxides or phosphate substances, and are deposited and are separated from water. A sludge reduction is greater than 97%. The processor provided by the invention can be widely adopted in sludge processing and treatment in urban domestic sewage treatment plants, urban comprehensive sewage treatment plants, and urban chemical engineering wastewater treatment plants. Therefore, a clean and low-energy-consumption solution is provided for sewage safe treatment.

Description

technical field [0001] The present invention relates to the technology of rapid and safe treatment of excess sludge, especially the treatment and disposal of excess sludge in chemical sewage treatment plants, urban comprehensive sewage treatment plants, and urban domestic sewage treatment plants. The sludge is treated and disposed quickly and safely to solve the high cost of excess sludge treatment and disposal. After the excess water sludge is treated by this technology, the purpose of sludge reduction can be achieved. Background technique [0002] From the 1980s to the end of the "Eleventh Five-Year Plan", the number of sewage treatment plants in my country has increased from 37 to nearly 3,000. The blowout development of sewage plants has also brought about the problem of sludge treatment and disposal. At present, there are only more than 50 sewage plants in my country that have built sludge digestion devices at the same time as the plants, and only more than 20 of them c...
