Abstract

Wetland park is one of the city's major ecological infrastructures, undertaking the dual functions of improving the ecological environment and providing recreational places. Studying the reasonable construction methods of the wetland park is very important for its sustainable development. In this paper, a wetland park with an area of 173.5 hectares located in Zhangzhou City, Fujian Province, China is taken as an example to show how to apply the concepts and measures of resource saving and environment friendliness to the three development phases of planning, construction and management of the park. Measures of resource saving include land conservation, water resource conservation, energy conservation, vegetation optimization, application of low carbon construction techniques, indigenous materials and intelligent technologies used in management. Environment friendly measures include development intensity control, man-made wetland construction, friendly materials adoption, fibre resource using wooden plank, road building on stilts, topsoil and native vegetation protection during construction, noise control, pesticide usage reduction in management, bio-safety disposal of garbage and tourists capacity control. Resource saving and environment friendly wetland park construction can effectively promote the sustainable development of the park.

Abstract

The degradation of Reactive Red 6B (RR6B) wastewater was treated by Fenton oxidation using on-line spectrophotometric monitoring technology. The ratio of peroxide hydroxide concentration and ferrous ion dosage (HF) was investigated. Dyeing degradation process followed first order kinetics and Behnajady - Modirshahla-Ghanbery kinetics because of above 0.98 R². Fenton process transient reaction rate and instant hydroxyl radical concentration was calculated. The optimum HF was 143 with 98% dye removal, 0.05mol/(L·s) instant transient reaction rate and 2.4×10^-11mol/L initial hydroxyl radical concentration.
