Accompanying drawing explanation
Fig. 1 is the granular manufacture method schema to sewage sludge compounded mix of the present invention.
Fig. 2 is the granular bed of packings structural representation to sewage sludge compounded mix of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
The moiety of sewage sludge compounded mix of giving of the present invention comprises: mud, hard coal, starch, polymerize aluminum chloride and sponge iron.To sewage sludge, through chemical modification and heat modification, granulate, it has good phosphor-removing effect.
Concrete preparation flow is as follows:
S101: get mud some, this mud is preferably the mud of waterworks settling tank, and the mud of waterworks settling tank itself has certain soil removability, and it is low to obtain expense.By mud seasoning, after being dried, utilize pulverizer to pulverize, the mud after pulverizing is sieved, remove the foreign material such as rubble, fragment of brick, obtain mud raw material.
S102: mud raw material is mixed according to 1:0.2 ~ 0.5 weight ratio with hard coal, obtain compound;
S103: add starch paste in compound, wherein starch paste consumption is the 2-5% of compound weight, and mixing and stirring, obtains mud mixture;
S104: by mixture, by granulator granulation, be dried after granulation is complete;
S105: the temperature roasting for some time by dried particle with 300 ~ 600 ℃, this time is preferably 3 hours, roasting can be carried out in retort furnace;
S106: the polymeric aluminum chlorides solution that is 5 ~ 10% by concentration by the particle after roasting soaks for some time, soaks into completely to particle, and this time can be 12 hours, by the immersion particles of about 12 hours, can soak into completely;
S107: the particle soaking and sponge iron are mixed to get of the present invention to sewage sludge compounded mix according to 1:0.2 ~ 0.5 weight ratio.
The high-efficiency environment friendly material of utilizing waterworks waste processing to sewage sludge compounded mix of the present invention, pollution-free, expense is low, through chemical modification and heat modification, granulates, and it has good phosphor-removing effect.Dephosphorization efficiency by using is high, and nitrogen is also had to certain adsorptive power, has nitrogen fixation.
In order to make the granular sewage sludge compounded mix of giving of the present invention reach better wastewater treatment efficiency, the granular anti-granularity of sewage sludge compounded mix layering of giving of the present invention can be layed in bed of packings, this laying method can be brought into play the granular adsorptive power to sewage sludge compounded mix of the present invention to greatest extent.Particularly.
As shown in Figure 2, bed of packings is pressed the anti-granularity of different-grain diameter layers of material and is laid, and the bed of packings in Fig. 2 is divided into three sections, but those skilled in the art should understand, the number of segmentation can be less than or more than three sections, the present invention is not intended to limit segmentation number, only usings three sections as schematically illustrating.
Each section of bed of packings forms by small particle size layer 1 and large particle diameter layer 2, small particle size layer 1 is layed on large particle diameter layer 2, small particle size layer 1 is comprised of the granular sewage sludge compounded mix of giving of the present invention, large particle diameter layer 2 can be comprised of gas concrete brickbat grain, and the section of each after filling is all that particle diameter is ascending from top to bottom like this.
