Embodiment 1

[0031] A treatment method for garbage permeate, comprising the following steps:

[0032] Step 1. Flocculation and sedimentation treatment: Send 1000L of garbage permeate into the flocculation sedimentation tank, which adopts a flat flow sedimentation tank, and controls the average flow rate in the sedimentation tank to be 25-50mm / s; then add 30L mass fraction of 2% quaternary ammonium cationic polymer compound solution as decolorizer, 20L concentration of 20g / L polyaluminum chloride solution and 10L mass fraction of 0.1% polyacrylamide solution, fully stirred and mixed, let stand 1 hour.

[0033] Step 2, Fenton oxidation treatment: Send the supernatant I obtained after step 1 to stand still into the Fenton pool, then add sulfuric acid to the supernatant I, and adjust the pH value of the supernatant I to 3; Add 10L mass fraction of 30% hydrogen peroxide solution and 10L concentration of 50g / L FeSO 4 ·7H 2 O aqueous solution, stirred thoroughly to mix the reaction, and then s...

Embodiment 2

[0041] A treatment method for garbage permeate, comprising the following steps:

[0042] Step 1. Flocculation and sedimentation treatment: Send 2000L of garbage permeate into the flocculation sedimentation tank, which adopts a flat flow sedimentation tank, and controls the average flow rate in the sedimentation tank to be 10-25mm / s; then add 60L mass fraction is 2% quaternary ammonium type cationic macromolecular compound solution as decolorizer, 40L concentration is 40g / L polyaluminum chloride solution and 20L mass fraction is 0.1% polyacrylamide solution, fully stir and mix, let stand 1 hour.

Abstract

The invention provides a rubbish penetrating fluid treatment method. The rubbish penetrating fluid treatment method comprises flocculent settling treatment, Fenton oxidation treatment and activated carbon adsorption treatment which are performed in sequence. First in the flocculent settling treatment step, by combined use of a decolorizing agent, PAC and PAM, the very good decolorizing effect is achieved, the chromaticity can be reduced by at least two orders of magnitude, and CODs, BODs and heavy metal ions such as arsenite, lead and mercury in water can be removed effectively. Next, organic pollutants difficult to degrade can be removed more effectively through Fenton oxidation under the acidic conditions. Finally, adsorption is performed by utilizing activated carbon. Therefore, the rubbish penetrating fluid treatment method is low in cost, high in effect and simple to operate and saves manpower and material resources. Moreover, the treatment degree is high, the effect is stable, the penetrating fluid chromaticity, CODs, BODs, the heavy metal content and ammonia nitrogen of rubbish treated through the method reach the emission standard.

Description

technical field [0001] The invention relates to the technical field of garbage permeate treatment, in particular to a treatment method for garbage permeate. Background technique [0002] Garbage seepage fluid is the sewage seeped out due to fermentation, rainwater washing, surface water and groundwater soaking during the process of garbage stacking and landfilling. Permeate is a kind of high-concentration organic wastewater with complex components. Its properties depend on factors such as garbage components, garbage particle size, compaction degree, on-site climate, hydrological conditions, and landfill time. Generally speaking, the water quality is complex and the hazards High resistance, high concentration of CODcr and BOD5, high content of ammonia nitrogen, large changes in water quality, high metal content and so on. Most cities in my country use sanitary landfill as the basic way of garbage disposal. In the future, sanitary landfill will still be the basic way of domes...
