Resumen

Glenbrook Lagoon, an 8 hectare lake receiving rainfall runoff from a residential catchment, is experiencing nutrient enrichment problems expressed as excessive aquatic plant presence. This study aims to assess the relative nutrient contribution of the total system compartments, including catchment loading, water column, aquatic plants and surface sediment. This information is utilised in the formulation of management strategies which may produce a sustainable nutrient reduction and general improvement in the system. The total nutrient content of the aquatic system was determined to be high in

Resumen

Coombabah Lake is a sub-tropical, semi-urbanised, shallow lagoon in southern Moreton Bay (Australia), recognised nationally and internationally as an important conservation and habitat zone. However, significant increases in urban development have occurred within the lagoon catchment in recent times, raising concerns over the sustainability of the lagoon ecosystem. This is typical of many estuarine environments which are ecologically and economically important waterways that often become surrounded by urban development and therefore experience degradation of water and sediment quality.

Resumen

This thesis covers work carried out on algae bioreactors as a tertiary treatment process for wastewater treatment. The process was primarily assessed by the removal of Phosphorus and Nitrogen as an alternative to chemical and bacterial removal. Algal bioreactors would have the added advantage of carbon sequestration and a by-product in the energy rich algal biomass that should be exploited in the existing AD capacity. Laboratory scale bioreactors were run (4.5-30L) using the secondary treated final effluent from the local Loughborough sewage works. In a preliminary series of experiments severa

Resumen

Coastal waterbodies and their catchments have been highly modified, leading to altered flushing and eutrophication. Strategies to manage water flow to either maintain water levels or reduce salt-water intrusion and mitigate impacts to coastal waterbodies include engineering approaches such as the construction of surge barriers and river diversions and manipulation of sandbars. Climate change is increasingly impacting coastal waterbodies with predictions of increased drying and significant changes to rainfall patterns. Consequently, engineering management strategies are likely to increase, but

Secondly, the role biological activity plays in carbon cycling is also examined in Dapeng Bay, especially after a natural nutrient pulse. For the first objective, water samples in Dapeng Bay were obtained from 16 sites. Sampled data

Moreover, through livestock production in the land and grass filtration areas, as much as 20% of the total operation cost of the complex is recovered. However, in terms of the volume of waste water treated per unit area, grass and land filtration are considered to be less efficient than stabilization ponds.

Resumen

碩士<br>國立中山大學<br>海洋環境及工程學系研究所<br>95<br>Tapeng Bay is the second largest lagoon in Taiwan. The biological and ecological environments are an autotrophic system and are influenced by seasonal variability, terrestrial pollutant inputs and the exchange rates with seawater. There’re intense oyster culture and fish farming activities in the bay before July, 2002. The oyster was the most important spineless member in the lagoon. They would filtrate microplankton and detritus; they would also excrete nutrient and consume dissolved oxygen. Therefore, oyster played a very crucial role in the Tapeng Bay.

Resumen

High rate algal ponds (HRAPs) can be utilised as an efficient and economical wastewater treatment method while also producing algal biomass. This study focused on the use of HRAPs to assimilate nutrients from secondary lagoon effluent and investigated various methods in which to enhance the algal biomass productivity of the HRAPs. The natural operation, productive potential, biomass production, nutrient removal capacity and environmental conditions were observed. From these findings, three experiments were proposed to enhance biomass production and in turn, the nutrient removal of the HRAPs. T
