Abstract
The invention discloses belongs to the technical field of sludge deep dehydration and relates to a novel sludge deep dehydration rinsing agent. The rinsing agent comprises the following substance according to weight percentage: 5 to 30 percent of activated charcoal powder, 30 to 70 percent of fly ash, 5 to 30 percent of quicklime powder, and 1 to 20 percent of polyaluminum ferric chloride. The invention further discloses a using method of the rinsing agent. In the invention, the rinsing agent added is cheap material, and replaces rinsing agents such as conventional polyacrylamide flocculating agent, iron trichloride, calcium oxide and the like, and after dehydration, sludge cakes can be used as raw material for building material and fuel.
Description
Technical field
The invention belongs to the deeply dehydrating sludge technical field, be specifically related to a kind of novel deeply dehydrating sludge amendment.
Background technology
Sludge dewatering be in the sludge treatment expense higher but and one of crucial process system, the quality of dewatering performance of sludge is directly connected to the quality of whole sludge treating system.Mostly conventional at present sludge conditioner is iron trichloride+lime, this method can play the effect of certain sludge modification, but iron trichloride is bigger to the corrosion of equipment, and added amount of chemical is big in addition, increase a large amount of chlorions in the filtrate, the processing of mud filtrate has been increased very big difficulty.Also add the solid content that dried solid improves mud in the oriented mud, this method does not change the characteristic of mud, but also has increased volume and the intractability of mud.
Summary of the invention
The present invention is directed to the defective of existing sludge conditioner, propose a kind of novel deeply dehydrating sludge amendment, this amendment can improve the effect of sludge conditioning, reduce cost, in addition equipment is not had corrosion, can also increase intensity and the fuel value of mud, for follow-up sludge deep is provided by the condition that provides.
A kind of deeply dehydrating sludge amendment, it is made up of the material of following weight percent: active carbon powder 5-30%, flyash 30-70%, calcium lime powder 5-30%, aluminium iron polychloride 1-20%.
A kind of method of deeply dehydrating sludge is characterized in that, carries out according to following steps:
(1) by mass ratio active carbon powder 5-30%, flyash 30-70%, calcium lime powder 5-30% are mixed, make sludge conditioner A;
(2) aluminium iron polychloride 1-20% is added water and be made into the solution that massfraction is 10-1000g/L, make sludge conditioner B;
(3) sludge conditioner A is added in the moisture mud stir, the add-on of sludge conditioner A is the 1-20% of sludge quality, adds sludge conditioner B then and carries out mechanically mixing, pumps into deeply dehydrating sludge equipment with sludge pump then, carries out mechanical dehydration.
Described moisture mud is municipal sludge, alum sludge, chemical engineering sludge or pharmacy mud.
Beneficial effect of the present invention: the amendment that adds among the present invention all is cheap material, substitutes amendments such as conventional polyacrylamide flocculant, iron trichloride, lime, and the sludge cake after the dehydration can be used as the raw material of material of construction, fuel.Among the present invention, moisture content of the cake can be reduced to 40-60% after the sludge dewatering, mud resistivity near 10
5-10
7S
2/ g.Because the reduction of resistivity, after natural drying 1-2 days, water ratio can drop to below 30%.
