Embodiment 1

[0034] A method for preparing water treatment chemicals by using sludge residues, step 1:

[0035] Discharge the sludge residue containing waste water into the No. 1 sedimentation tank, let it stand for 0.5 to 2 hours, discharge the waste water on the top of the sludge residue, and discharge the waste water into the waste water pool. The inside of the waste water pool is equipped with a stirring device, and the stirring speed is 1 minute 20 laps, put the sludge residue into the inside of the drying furnace, the drying temperature is 800 degrees, and the drying time is 5-6 hours. The wastewater in the sludge residue can be separated through the No. 1 sedimentation tank, so that the water content can be obtained Low sludge residue, by putting the sludge residue into the drying furnace for drying, the sludge residue can be carbonized;

[0036] Step two:

[0037] Add concentrated sulfuric acid and concentrated hydrochloric acid into No. 1 stirring tank, the volume ratio of concen...

Abstract

The invention discloses a method for preparing a water treatment agent from sludge residues, belonging to the technical field of sludge residues. According to the method sludge residues are dried and carbonized, and the carbonized sludge residues and an adsorption decolorizing agent are mixed and stirred, so the sludge residues and the adsorption decolorizing agent are fused, the effect of cleaning water can be achieved, and the problems that sewage treatment cost is high since a large number of chemical agents are needed for treatment in existing sewage treatment and that the practicability of sewage treatment is reduced since sewage cannot be purified through sludge in the sewage in the prior art are overcome. A mixture of concentrated sulfuric acid and concentrated hydrochloric acid is arranged in the sludge residues, and calcium hydroxide and sewage can be subjected to acid-base neutralization, so the pH value of the sewage is neutralized.

Description

technical field [0001] The invention relates to the technical field of sludge residues, in particular to a method for preparing water treatment chemicals from sludge residues. Background technique [0002] Industrial sewage and urban domestic sewage will produce sludge after treatment. The amount of sludge usually accounts for 0.3% to 0.5% of the sewage volume, and the mass is about 1% to 2% of the sewage treatment volume. The composition, nature and quantity of sludge mainly depend on the source of wastewater and wastewater treatment process. [0003] Existing sewage treatment requires a large amount of chemical agents for treatment, which makes the cost of sewage treatment relatively high, and the sludge in the sewage cannot be used to purify the sewage, thereby reducing the practicability of sewage treatment. Contents of the invention [0004] (1) Solved technical problems [0005] For the deficiencies in the prior art, the invention provides a kind of method that uti...
