Abstract
The invention relates to an oily sludge concentrating agent as well as preparation and application thereof. The oily sludge concentrating agent comprises cement, fly ash, diatomite and polyaluminum, wherein the proportion by mass of the cement, the fly ash, the diatomite and the polyaluminum is 1:(0.5-2.5):(0.5-2.5):(0.005-0.05); and a production method of the oily sludge concentrating agent comprises the following steps of: firstly grinding the fly ash into fly ash powder in 100-300 meshes, mixing with the diatomite in 100-300 meshes, the cement in 100-300 meshes and the polyaluminum in 100-300 meshes according to the proportion by mass and uniformly stirring. Oil, water and sludge can be thoroughly separated by adding 0.5-1.5 percent by mass of oily sludge concentrating agent into oily sludge containing 99 percent of water; and the oily sludge concentrating agent has the advantages of high settling velocity, good sludge concentrating effect, less dosage, low cost and convenience in feeding.
Description
Technical field
The present invention relates to a kind of oily sludge enriching agent and preparation and application.
Background technology
In oil-containing sewage treatment system; All can produce a large amount of oily sludges through conventional sewage treatment process such as deposition, filtration, air supportings; The processing of oily sludge generally comprises three parts: the first step is concentrating of mud, and second step was mummification, and the 3rd step was harmless treatment.
Oily sludge concentrates an important step as sludge treatment, in sludge treatment, occupies critical role.Mud concentrates generally will be concentrated to 85～97% with moisture 97～99% oily sludge, reduces 3～5 times to the volume of oily sludge, and then carries out subsequent disposal.In existing mud concentration technique, generally adopt lime and PAM to come oily sludge is carried out the mud concentration, the deficiency of this method is: 1, concentrated effect is poor; 2, settling velocity is slow; 3, dosing is big, and cost is high, and the cycle is long; 4, want segmentation to add during dosing, technology is loaded down with trivial details.
Summary of the invention
The purpose of this invention is to provide that a kind of concentrated effect is good, speed is fast, dosing is little, cost is low, add easily efficient oily sludge enriching agent and working method thereof.
Efficient oily sludge enriching agent of the present invention is made up of cement, flyash, zeyssatite and polymeric aluminum; It is characterized in that: the quality proportioning of cement, flyash, zeyssatite and polymeric aluminum is 1: (0.5～2.5): (0.5～2.5): (0.005～0.05); Its working method is at first flyash to be ground to form 100～300 purpose flyash powder, is mixed into evenly with zeyssatite, cement, polymeric aluminum according to the quality proportioning again.
Above-mentioned zeyssatite is 100～300 purpose commodity super-cells.
Above-mentioned cement is commercially available oil well cement, silicate cement, the slag cement or the cement etc. that is in harmonious proportion.
Cement, flyash, diatomaceous true density are high, specific area is big, inside is pore texture and cheap; The highly effective sludge enriching agent with join in the oily sludge after water mixes; In the efficient oily sludge enriching agent of forming by cement, flyash, zeyssatite and polymeric aluminum with positive charge can compress the colloid electrostatic double layer of oil droplet and mud granule in the oily sludge; Make it to be easy to assemble, the polymeric oil droplet floats rapidly, and polymeric mud sinks rapidly.The efficient oily sludge enriching agent of being made up of cement, flyash, zeyssatite and polymeric aluminum is a kind of confection, and the dosing method in oily sludge is easy for once adding technology.
Facts have proved: the invention has the beneficial effects as follows that oil, water, mud separate thoroughly, settling velocity is fast, and the mud concentrated effect is good, and dose is few, cost is low and add advantage easily.
Embodiment
Further set forth the present invention below in conjunction with embodiment.
Experiment control methods among the embodiment: get moisture in the backwashing sewage water pond for recovering of oil field, Tarim Basin joint station Sewage treatment systems and be each sample 100mL of oily sludge of 99%; Under 50 ℃ of conditions, adding moisture is the oily sludge enriching agent and lime and SEPIGEL 305 (PAM) commonly used of proportioning among the different embodiment of 99% oily sludge quality 0.5～1.5%, each sample is rocked the distribution of the profit mud of even back observation thickened sludge and comes contrast effect.

Embodiment 3:
With 425# slag cement, 250 purpose flyash powder, zeyssatite and polymeric aluminum according to 1: 1.5: 1.5: the efficient oily sludge enriching agent of 3# is evenly processed in 0.03 be mixed into.Experimental data is seen table 1.
Embodiment 4:
With commercially available 425# silicate cement, 250 purpose flyash powder, zeyssatite and polymeric aluminum according to 1: 1.5: 1.5: 0.04 be mixed and made into the efficient oily sludge enriching agent of 4#.Experimental data is seen table 1.
Embodiment 5:
With 425# slag cement, 250 purpose flyash powder, zeyssatite and polymeric aluminum according to 1: 2: 1.5: 0.05 be mixed and made into the efficient oily sludge enriching agent of 5#.Experimental data is seen table 1.
The concentrated effect cartogram of table 1 oily sludge
Can know from last table: efficient oily sludge enriching agent of the present invention compare with the mud enriching agent of routine have oil, water, mud separates thoroughly; Velocity of separation is fast, and the interface is clear, and the mud concentrated effect is good; It is low to add dose, adopts the Chemical Composition of full-inorganic also to have characteristics with low cost; Test shows: practice thrift dosing 50%, practice thrift dispensing fund 80%.
