    Research on In-situ Sludge Solidification in the Ecological Refuse Landfill Closure Project by ZHANG Xiaoyu, ZHOU Xianjin, CAO Jun

    Published 2021-01-01
    “…For the site pilot test of in-situ sludge solidification in a large ecological landfill closure project in southwest China,this paper adopts five kinds of curing agent mix ratios for site construction,adds curing agent and conducts in-situ mixing with cleaning and mixing equipment after pretreatment of sludge,and drills and samples the treated refuse soil after rolling and curing.The test results show that the sludge treated with five kinds of curing agents could meet the design requirements on pH,moisture content,shear strength and unconfined compressive strength.Through the comparison of shear strength and unconfined compressive strength,the effect of No.5 curing agent is the best,that is,in the curing agent,the ordinary silicate content is 19.3%,the fly ash content is 6.43%,and the curing agent ratio is 25.73%.In the actual construction,the No.5 mix ratio is widely used.In addition,according to the difference of physical properties of sludge in level and treatment direction,the mix ratio of curing agent and the parameters of mixing equipment shall be adjusted appropriately to ensure the uniformity of sludge curing effect.…”

    Published 2016-01-01
    “…Objective To analyze the correlation of psychological status,brain derived neurotrophic factor(BDNF) and glial cell-derived neurotrophic factor(GDNF) levels in young patients accepting maintenance hemodialysis.Methods Ninety-seven cases of young patients accepting maintenance hemodialysis were selected as the observation group,while 50 cases of healthy people were chosen as the control group.The symptom check list-90(SCL-90) was used to assess mental and psychological state.BDNF and GDNF were tested using ELISA.The relationship between psychological state and BDNF,GDNF was also analyzed.Results Somatization,depression,anxiety,and hostility scores in the observation group were significantly increased as compared with the norm and those in the control group(P<0.05).There was no significant difference in interpersonal relationships,terror,paranoid,and psychotic scores between the observation group with the norm and the control group(P>0.05).GDNF and BDNF in the observation group were significantly decreased as compared with the control group(P<0.05).There was no significant difference between male and female patients in the observation group(P>0.05).Correlation analysis showed that somatization and hostility in SCL-90 scores showed no significant negative correlation with BDNF(r =- 0.028,- 0.047,P>0.05),and obsessive-compressive,anxiety and depression showed significant correlation with BDNF(r=-0.317,- 0.294,- 0.309,P<0.05).Somatization and hostility in SCL-90 scores showed no significant negative correlation with GDNF(r =- 0.079,0.021,P>0.05),and obsessive-compressive,anxiety and depression showed significant correlation with GDNF(r=- 0.395,- 0.317,- 0.374,P<0.05).Conclusions Psychological status in young patients accepting maintenance hemodialysis showed decreased BDNF and GDNF as well as psychological disorders such as anxiety,depression,etc.The decreases in GDNF and BDNF may contribute to psychological disorder.…”
