Накратко на български

Анаеробното разлагане се тества за пречистване на отпадни води от остатъци от лекарства. Това помага за намаляване на замърсяването на водите и разходите за енергия при пречистването им, което предпазва водните организми.

Removal of pharmaceutical micro-pollutants from waste water by anaerobic digestion and its effect on nitrogen recovery from digestate by micro-algae.

In recent years there has been increasing attention towards identification, effect and abatement of residues of pharmaceutical (PR) in the environment. PRs generally originate from within the urban-environments and may finally reach the natural aquatic environment as some of them are only partially removed in Waste Water Treatment Plants (WWTP). They are typically found at very low concentrations in the environment and are unlikely to affect human health but could cause damage to aquatic organisms and are included as watchlist-substances in the Water Framework Directives. Anaerobic digestion (AD), a common tertiary treatment, is a biological process where different microorganisms take part. PRs may have an effect on the microorganism of this process inhibiting the system. The treatment of sewage sludge is a common application of AD in the wastewater industry. Whilst removal of PRs by AD in sludge has received some research interest, this project investigated the application of AD for the removal of PRs from wastewater, which contains many of these compounds. Previous studies have shown that advanced treatment of the aqueous phase of wastewater is expensive and energy intensive whilst only providing partial removal of PRs. Removal of PRs by AD would reduce the financial and carbon cost of treatment due to its potential to generate energy from waste, and this would thus provide a viable technique to reduce a proportion of PR pollution of water in all EU member states. Typical barriers to wastewater treatment by AD are washout of bacteria and corresponding low turnover, process sensitivity to inhibitors and lack of nitrogen (N) and phosphorous (P) removal from wastewater. Therefore, the aims of this project were: 1. Investigate the efficacy of AD for the removal of PR. 2. The application of AD to the direct treatment of waste waters. 3. Combine PR removal by AD with nutrient recovery by microalgae cultivation. 4. Elaborate the scope for river water quality improvement by these techniques, thus contributing to the European aims of water protection and resource efficiency.

Цел на проекта

Since the advent of the water framework directive (WFD), integrated pollution abatement and river water quality improvement has become a major focus in the management of water resources. At the same time, improving analytical capabilities and ecotoxicological understanding highlighted, somewhat counter-intuitively, new threats to water quality. Micropollutants in the form of pharmaceutical residues (PR) are one such emerging threat, and have been included in the most recent list of related WFD priority and related watch-list substances.This research project will address this threat by application of a combination of existing and novel techniques: 1) investigate the efficacy of anaerobic digestion (AD) for the removal of these PRs not only in conventional treatment of sludges, but also on 2) the novel application of AD to the direct treatment of point source waste waters waste waters rich in these pollutants (e.g. hospital or industry), including feasibility studies on the transfer of membrane-bioreactor technologies from aerobic to anaerobic treatment. Furthermore, 3) the project will combine PR removal by AD with biological nutrient removal (nitrogen) by micro-algae cultivation, thus addressing one of the drawbacks of AD: the lack of nitrogen removal.A particular inter-disciplinary perspective of this project is the inter-relation between 3 aspects of investigation: pollutant removal by AD, resultant ecotoxicological effects on algae and subsequently the recovery of nutrients by algae. The final aim of the project is to elaborate the scope for river water improvement by these techniques, thus contributing to the European aims of water protection and resource efficiency. This element in particular will be supported by close collaboration with a German public water company, a UK SME from the water industry, and a French University, thus increasing the project’s potential for impact and uptake due to generation of realistic and industry relevant outputs.
