The invention discloses a method for producing a compound fertilizer containing nitrate nitrogen potassium sulphate. The method is achieved by the following steps: (1) preparing ammonium nitrate phosphorus slurry, namely dissolving ammonium nitrate phosphorus by using condensate water at 50-80 DEG C or compound fertilizer exhaust washing liquor; (2) preparing a mixed acid, namely enabling a sulfuric acid solution to react with potassium chloride in a transfer tank to generate potassium hydrogen sulfate, overflowing KHSO4 generated by reaction and excessive H2SO4 solution to a mixed acid geosyncline, and mixing with a phosphoric acid solution which is metered by an ultraphosphate flow meter to generate the mixed acid; (3) carrying out neutral reaction on gas ammonia and mixed acid in a reactor, so as to obtain neutral slurry; (4) mixing the neutral slurry with the ammonium nitrate phosphorus slurry in a feeder trough to form mixed slurry; and (5) spraying the mixed slurry into a pelletizer, so as to obtain the compound fertilizer containing nitrate nitrogen potassium sulphate. The usage of steam is saved, the compound fertilizer particle is good in smoothness, and uniform in granularity, the whiteness is improved, the moisture is well controlled, the utilization rate of the fertilizer is improved, the soil contamination is reduced, and healthy growth of the plant is promoted.

The invention discloses an assembled dedicated pedestrian street, a pavement method of the pedestrian street and a design method of the pedestrian street, and aims at solving the problem that historical sidewalks in towns and countries, especially streets in old towns, are seriously damaged. The assembled dedicated pedestrian street comprises a street body, matched equipment and a drainage system in an assembling manner, wherein inside a geosynclines, a glass fiber reinforced plastics grid plate bottom and glass fiber reinforced plastics square tube curbs at two sides form a bottom plate to form a bottom plate groove; a medium sand layer, a common permeable brick roadbed, a permeable rubber rick and a rubber blind road brick pavement are arranged inside the groove to form the street body; inner and outer outfalls are formed at two sides of each curb; an inner opening is attached to the pavement; an outer opening is connected with an underground glass fiber reinforced plastics drainage pipeline through a branch pipe to form the drainage system. Table and chair facilities can be manufactured into artware to be fixed on the bottom plate. The pedestrian street is not overhauled, change old parts with new parts, and broadened or dismantled according to the requirements, and all components can be recovered and processed to be recycled, so that the life cycle cost is low. The assembled dedicated pedestrian street can be arranged on the outer surfaces of residential and commercial buildings at the sides of urban and rural public transport roads and highways, streets, parks, fields and other pedestrian floors in a paving manner.
