In order to solve the problems of poor accuracy and long time-consuming of traditional methods in the assessment of sudden oil spill pollution from ships, this paper takes the navigation area in the South China Sea as the research object and proposes to build the assessment model of ship oil spill...
A Method for Optimizing the Allocation of Sea Resources Based on Ecological Environment Protection
CLEANWAS
With the increasing demand for marine resources, the marine ecological environment system is gradually destroyed. The traditional allocation of marine resources has been unable to meet the global resource search, resulting in poor distribution uniformity of marine resources and high packet loss rate...
The Existing Forms of Denitrifiable Reductive Groups in Sludge
CLEANWAS
The reductive gas composition produced by the reburning of sludge can reduce NOx in flue gases to N2, which provides a new idea for the study of gas denitration, and at the same time makes denitration by sludge reburning become an important part of gas denitration research. However, due to the...
Characteristics Analysis of Precipitation Observations and Climate Change Along the High-speed Railway in Jiangsu
CLEANWAS
High-speed railway (HSR) is severely affected by precipitation disasters. There are many studies on precipitation and precipitation disasters, most of which are precipitation and analysis of disasters caused by precipitation, and few explain climate changes caused by precipitation. This paper uses...
Does Manufacturing Industry Agglomeration Aggravate Regional Pollution? -- Evidence from 271 Prefecture-level Cities in China
CLEANWAS
To find out the relationship between industrial agglomeration and environmental pollution, this paper carried out empirical research on the panel data collected from 271 prefecture-level cities in China from 2004 to 2017 through a spatial panel econometric model. It reviewed the influence of...
An Experimental Study of Energy Dissipation of Sea Grass in a Dam Break Flume
CLEANWAS
An experimental study was carried out to investigate the energy dissipation characteristics of sea grass in a dam break flume. Dam break flows were generated in a flume. A steel ball was subjected to the dam break flow, and then climbed on a slope. Artificial sea grass was used as the energy...
A review on application of external carbon sources for denitrification for wastewater treatment
Water and Wastewater Treatment
With the increase in industrial and agricultural activities, huge amount of wastewater containing nitrogen is produced. Biological denitrification is currently the most widely used, sustainable and cost-effective process to remove nitrogen from wastewater. In biological denitrification, application...
Physio-chemical evaluation and Co-combustion efficiency of different biomass waste fractions with indigenous coal blends for utilization as alternative fuel
Solid Waste Management
Severe energy crisis and vilest economic conditions in Pakistan demand the country’s energy portfolio to be revised with increased reliance on indigenous energy resources. The perspective of utilization of abundantly available biomass waste fractions as a fuel alone and their co-combustion with two...
