Embodiment

[0025] Experimental equipment: two sets of electrochemical oxidation reaction processors with an effective volume of 0.3L

[0026] One DC power supply

[0027] Sludge pump N: 0.37kw, Q: 0.5-2m 3 / h two

[0028] One solid-liquid separator

[0029] Analytical instrument: 10,000-level electronic balance

[0030] infrared oven

[0031] Water circulation vacuum pump

[0032] Sludge source: Changzhou Jiangbian Sewage Treatment Plant

[0033] Experimental steps:

[0034] 1. Start the sludge pump and adjust the flow rate to 0.5m 3 / h, add the wet sludge pump into the reactor until the reactor overflow water level line, 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.

[0035] 2. Adjust the flow meter at the outlet of the sludge pump to adjust the flow to 1m 3 / h, sampled after 20 minutes.

[0036] 3. The samples taken are three groups of balanced control samples,...

Abstract

The invention discloses a sludge processing technology by electrochemical direct oxidation. A two-stage electrochemical direct oxidation technology is adopted to carry out oxygenolysis processing on sludge of which the moisture content is 99.6%, and the residual sludge decrement is above 95%. The sludge processing technology by the electrochemical direct oxidation can be widely applied to sludge processing and disposal for city life sewage treatment plants, city integrated sewage treatment plants and city chemical industry sewage treatment plants, and a clean and low energy consumption solution is provided for the safe processing and disposal of the sludge.

Description

technical field [0001] The invention relates to a treatment process for electrochemical direct oxidation of sludge, especially for the treatment and disposal of excess sludge in urban comprehensive sewage treatment plants. The treatment process can quickly and harmlessly detoxify excess sludge in urban sewage plants. Treatment and disposal to maximize the purpose of sludge reduction. 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 have sludge devices that can really play a role. The chaos of sludge siege is difficult to solve, and the dispute over technical routes is ...
