Malodorous compounds arise at practically every stage of wastewater management, starting from the sewer network, via the technological sewage-treatment system, through to the sludge-management stage. The formation of hydrogen sulphide is a significant problem even while sewage remains in sewers, as anaerobic conditions prevalent in the network are conducive to wastewater putrefaction, and therefore contribute to increased malodorous emissions. The development of such anaerobic conditions is favoured by the oversizing of conduits or designs that feature inadequate gradients, causing wastewater in the network to stagnate. Where emissions to the air from wastewater occur, they are found to constitute a complex mixture of perhaps even 1000 different substances, produced under varying process conditions. Among those present are compounds of sulphur and nitrogen, chlorinated compounds, and other organics. In Poland, the issue of odour annoyance has not yet been subject to standardisation in either legal or methodological terms. Indeed, as only 11 EU Member States have regulations in place regarding air-quality standards, it is likely that such a law will soon be developed to try and resolve problems with odour annoyance, including those originating in the systems dealing with wastewater. This denotes a need to develop methods of counteracting the formation of odours, and those of a chemical nature are regarded as among the most effective, hence their growing popularity. They also abide by green-technology principles. Against that background, this article seeks to consider the process by which malodorous substances arise in sewer and wastewater-treatment systems, as well as to discuss methods of odour abatement. The work also presents the current legal regulations of relevance to the issue.

“…-N is easily adsorbed onto solids (Kojima et al 2011). The TP concentration varied from 0.010 to 0.203 mg L -1 , which was likely because phosphorus is strongly bound to soil particles (Li et al 2012;Liu et al 2012).…”

“…It has been reported that exogenous sources such as the effluent of rivers, atmospheric precipitation, and runoff have heavily influenced the water quality of the lakes and dam reservoirs (Luo et al 2007;Pang et al 2008;Wilson and Weng 2010;Zhao et al 2011;Bayram et al 2012;Li et al 2012;Elci and Selcuk 2013). For example, Li et al (2012) reported that nitrogen and phosphorus loads from the runoff accounted for 17 and 13 % of the TN and TP inputs to the Moshuihu Lake, Wuhan City, China. Another study conducted in the Taihu Lake, Jiangsu Province, China, showed that TN and TP contributed by the wet deposition accounted for about 7.3 and 16.5 % of the annual TN and TP inputs that occur via inflow rivers (Luo et al 2007).…”

Water transfer from the Qiantang River to the West Lake, Hangzhou City, China, has been performed since 1985 to improve the lake water quality. This study was conducted to assess the water quality and estimate the pollutant fluxes from different sources into the lake to enable better water quality management. Monthly variations in water quality variables, namely chemical oxygen demand (COD), 5-day biochemical oxygen demand (BOD 5 ), total phosphorus (TP), total nitrogen (TN), ammonium nitrogen (NH 4 ? -N), and nitrate nitrogen (NO 3 --N), and flow were analyzed for 1-year period from April 2012 to March 2013. The pollutant fluxes into the lake were mainly contributed by the water transferred from the Qiantang River, followed by runoff and rainfall. The results showed that the annual influxes of COD, BOD 5 , TP, TN, NO 3 --N, and NH 4 ? -N into the lake were 1, 595.3, 255.8, 8.2, 576.0, 360.3, and 84.2 t, respectively, while the annual fluxes out of the lake were 2,204. 6, 301.8, 7.1, 336.5, 191.6, and 36.1 t, respectively. The annual net flux of pollutants in decreasing order was TN [ COD, and nitrogen was found to be the major pollutant in the West Lake. It is recommended that the water transferred from the Qiantang River should be treated by chemical precipitation as well as denitrification technology to reduce the nitrogen concentration.

Wyniki składu ścieków ogólnospławnych opuszczających wybrany do badań przelew burzowy J1 w Łodzi wykazały, że wielkość ładunku kierowanego do odbiornika jest ściśle powiązana nie tylko z charakterem opadu, ale także z porą dnia, w której następuje wzmożony dopływ ścieków do kanalizacji, stopniem zanieczyszczenia terenu zlewni oraz ilością zalegających w sieci osadów. Dzięki wykonanym analizom laboratoryjnym, wzbogaconym wynikami pochodzącymi z pomiarów on-line, określono wielkość ładunku zanieczyszczeń badanych wskaź-ników (ChZT, BZT 5 , zawiesiny ogólne, zawiesiny mineralne, N-NH 4 , P og ) w zależności od zjawiska opadowego powodującego aktywację przelewu. Wyniki badań posłużyły również do określenia występowania efektu pierwszej fali zanieczyszczeń w ściekach emitowanych przez przelew J1 do odbiornika. Stwierdzono, że w trakcie roku 2012 objętego badaniami na 11 przeanalizowanych zjawisk, aż w 8 przypadkach efekt ten został zauważony, zarówno dla wszystkich badanych wskaźników, jak i tylko dla niektórych zależnie od opadu. Mimo podejmowanych działań prawnych oraz inwestycji służących ograniczeniu emisji ładunku zanieczyszczeń do odbiorników stan polskich rzek nadal nie należy jeszcze do dobrych. W związku z tym konieczna jest ciągła kontrola emisji zanieczyszczeń z uwzględ-nieniem nowoczesnych metod jej pomiaru oraz wykorzystania otrzymywanych wyników do opracowywania danych do programów komputerowych umożliwiają-cych realną ocenę tej emisji z systemu kanalizacji ogólnospławnej.Słowa kluczowe: kanalizacja ogólnospławna, przelewy burzowe, emisja zanieczyszczeń, pierwsza fala zanieczyszczeń 1 Autor do korespondencji: Agnieszka Brzezińska, Politechnika Łódzka, Instytut Inżynierii Śro-dowiska i Instalacji Budowlanych, 90-924 Łódź, Al.
