Agricultural water saving 10% urban water scarcity will be greatly alleviated
Qiu Baoxing, chairman of the China Urban Science Research Association, said on the 16th that my country's agricultural water consumption accounts for 61% of the country's total water resource utilization, while the effective utilization coefficient is only 0.51, which is 0.7 to 0.8 in developed countries. If my country's agriculture saves 10% of water, the shortage of urban water resources can be greatly alleviated.

Wastewater treatment technology: analysis of high salt wastewater treatment methods
High-salt wastewater refers to wastewater with a total salt content of at least 1%, which mainly comes from chemical plants, oil and natural gas collection and processing, etc. This wastewater contains a variety of substances (including salt, oil, organic heavy metals and radioactive substances). Salt wastewater is produced in a wide range of ways, and the amount of water is increasing year by year. The environmental impact of removing organic pollutants in saline wastewater is crucial. How to deal with high-salt wastewater, first we make a simple analysis of its different situations.

China Environmental Engineering and Services Industry Concentration Analysis
As of the end of 2016, the proportion of PPP candidate projects in the identification stage has shrunk, but still nearly 70%. For general warehousing projects, there is no mandatory execution time. The increase in the implementation rate is a market choice, and the PPP cooperation model between local governments and private enterprises is gradually maturing. However, the stricter standards of actual PPP projects have slowed down the total growth rate. In Q4, the monthly average of newly added projects was 263, which was lower than H1 (458) and Q3 (395). ). Calculated according to the caliber of projects in the implementation stage, the implementation rates at the end of January, March, June, September, and December were 20%, 22%, 24%, 26%, and 31.6%, showing a steady increase.
