Embodiment Construction
[0026] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0027] Step 1: Combine CaO with CaCl 2 Put into proportional water to mix evenly.
[0028] Step 2: Put in CO(NH 2 ) 2 Mix well with polymer water-absorbent resin.
[0029] Step 3: Add biologically active enzymes and mix well.
[0030] Step 4: Spray evenly in proportion.
[0031] The dosage of the above ratio is about 120kg, added to 1m 3 in the water, stir well to 2000m 2 Left and right urban roads are sprayed, and the implementation results show that the weight ratio is 0.28% bioactive enzyme, 0.07% polymer water-absorbent resin, 4.50% CO(NH 2 ) 2 , 4.40% CaCl 2 , 2.20% CaO, the TSP within 7 days after spraying is 0.30mg / m 3 , within the third grade of the ambient air quality standard; the weight ratio is 0.30% bioactive enzyme, 0.10% polymer water-absorbent resin, 4.75% CO(NH 2 ) 2 , 4.45% CaCl 2 , 2.25% CaO, the TSP within 7 days after spraying ...
