过磷酸钙化成期掺杂鸡粪制备高效磷肥的研究

研究了鸡粪细度、鸡粪用量、硫酸溶液初始温度、硫酸用量和硫酸浓度对改性磷肥化学性状的影响，并通过L9（3^4）正交试验研究了制备改性磷肥的最优工艺条件。结果表明，改性磷肥磷转化率随鸡粪细度、鸡粪用量、硫酸溶液初始温度和硫酸浓度的增加而降低，随硫酸用量的增加而增加。影响改性磷肥有效磷含量的因素大小顺序为硫酸浓度、鸡粪用量、硫酸溶液初始温度、硫酸用量，影响改性磷肥磷转化率的因素大小顺序为硫酸浓度、硫酸用量、鸡粪用量、硫酸溶液初始温度，两者的最优工艺设计为100g磷矿粉鸡粪用量15g、硫酸溶液初始温度70℃、硫酸用量125％（理论值）、硫酸浓度65％、鸡粪细度0．8mm。...

In order to increase phosphate fertilizer efficiency, single superphosphate loaded with chicken manure （SSPCM） was prepared at forming time. The experiments were conducted to study effects of the fineness and addition dosage of chicken manure, initial temperature, consumption and concentration of sulfur acid solution on the chemical characteristics of SSPCM. L9（3^4） orthogonal experiments were arranged to achieve the optimal conditions of SSPCM. Results showed that phosphate conversion rate of SSPCM decreased with the increase of fineness and addition dosage of chicken manure, initial temperature and concentration of sulfur acid solution, respectively, and increased with increase of sulfur acid consumption. L9（3^4） orthogonal tests indicated that the order of factors influencing the concentration of available phosphate in SSPCM was sulfur acid concentration, addition dosage of chicken manure, initial temperature and consumption of sulfur acid solution. The order of factors affecting phosphate convers
