The invention discloses a granulation method for 1, 3-bis(citraconoyl formimino) benzene. The method comprises the following steps: heating the 1, 3-bis(citraconoyl formimino) benzene to be completely molten into a liquid state; then carrying out heat preservation on the liquid-state 1, 3-bis(citraconoyl formimino) benzene for 1-2 hours at 43-45 DEG C, so that the liquid-state 1, 3-bis(citraconoyl formimino) benzene is converted into glassy-state 1, 3-bis(citraconoyl formimino) benzene; adding the glassy-state 1, 3-bis(citraconoyl formimino) benzene into a granulator, and carrying out granulation. The invention also discloses a granulation system. Continuous granulation can be realized by the granulation system. According to the granulation method and the granulation system, the defects that an existing granulation method is long in extrusion and granulation time and incapable of realizing continuous production are overcome; the 1, 3-bis(citraconoyl formimino) benzene is converted into a glassy state and is then granulated, so that the operation environment is greatly improved, and the production efficiency is improved; the granulation method and the granulation system have a favorable market prospect.

The invention discloses baking-free cylindrical attapulgite fire-retarding ceramsite. The key point of the technical scheme is that the baking-free cylindrical attapulgite fire-retarding ceramsite consists of high-viscosity attapulgite clay powder, attapulgite clay tailing powder, granulated blast-furnace slag powder, iron tailing powder, coal gangue powder, bauxite tailing powder, kieselguhr tailing powder and aluminate cement. The baking-free cylindrical attapulgite fire-retarding ceramsite is produced by the following steps of mixing the ingredients, granulating, maintaining, sieving and packaging. The baking-free cylindrical attapulgite fire-retarding ceramsite has a rough and hard surface, and is high in compression strength, low in heat conductivity, high in refractoriness and corrosion resistance and good in heat-preserving and sound-insulating effect; and a large amount of fine pores are formed in the ceramsite,. The baking-free cylindrical attapulgite fire-retarding ceramsiteis produced by utilizing multiple tailings comprehensively, so that the utilization rate of resources is improved, waste materials are changed into wealth, and environment is protected. Besides, the baking-free cylindrical attapulgite fire-retarding ceramsite is suitable for producing fire-retarding ceramsite concrete and heat-preserving and sound-insulating materials.

The invention discloses a common fertilizer special for sesbania in medium and low-yield fields in a Huang-Huai-Hai region and belongs to the field of fertilizer preparation. An organic matrix, an inorganic matrix, a nitrogen fertilizer, a phosphate fertilizer, a potassic fertilizer and a trace element chelating agent serve as basic raw materials. The preparation method comprises the following steps: spraying, granulating activating agents and preparing the fertilizer through disc granulation, wherein the nitrogen fertilizer, the phosphate fertilizer and the potassic fertilizer are mixed according to a mass ratio 5-9:14-20:0-2 of N:P2O5:K2O. The common fertilizer special for sesbania serving as a base fertilizer is applied at a time, is simple in production process, low in cost, environment-friendly, high in utilization rate and obvious in yield-increasing effect and is suitable for needs of common fertilizer special for sesbania in medium and low-yield fields in the Huang-Huai-Hai region and feed or particle production.

The invention relates to a sewage treatment process using a microbial carrier, which belongs to the technical field of sewage treatment and includes the following process steps: S1: sewage flows into a primary sedimentation tank for primary precipitation to obtain primary precipitated sewage; S2: after the initial precipitation in step S1 The sewage is filtered through the grid and then flows into the granulated sludge tank for treatment; S3: The sludge treated in the granulated sludge tank in step S2 is discharged into the secondary sedimentation tank for secondary sedimentation; S4: after the secondary sedimentation in step S3 After the sedimentation treatment in the secondary sedimentation tank, the sewage with qualified water quality indicators is discharged. The invention has higher high and low impact resistance of incoming water, and is not easy to produce the effect of sludge bulking.
