With the deepening of the ideological construction of ecological civilization and the strengthening of environmental protection, the disposal technology of solid waste is becoming more and more mature and perfect. Scientific disposal technology can reduce the impact of solid waste on the environment. Comprehensive utilization technology can realize the recycling of solid waste and improve the utilization rate of resources. Industrial solid waste has a large amount of production and is difficult to dispose. Many wastes contain certain hazardous pollutants, so scientific disposal measures are required. Therefore, this paper will conduct in-depth research and analysis on general industrial solid waste disposal and environmental management, and put forward some reasonable opinions and measures, aiming at further improving the technical level of industrial solid waste disposal. 展开更多

Objective: to study the clinical effect of humanized nursing concept in patients after hypertensive cerebral hemorrhage. Method: choose our hospital from August 2020 to June 2020120 cases of hypertension patients after cerebral hemorrhage as the main research object, and according to the random allocation into observation group and control group, each group 60 cases, choose the most routine nursing mode, observation group on the basis of the routine care mode, through the collection of complications of two groups, sports function rehabilitation, quality of life evaluation and nurse satisfaction score. Result: the complication rate of patients in the observation group was significantly lower than that of the control group, and the motor function recovery of patients was significantly higher than that of the control group, while the quality of life of patients were significantly higher than that of the positive control group, with P <0.05. Conclusion: after the implementation of humanized care for postoperative patients with hypertensive cerebral hemorrhage, it has significantly reduced the incidence of complications, increased the recovery of patients' motor function, thus improving the quality of survival, effectively promoted the doctor-patient relationship, increased patient compliance, and has clinical and promotion value. 展开更多
