A new urban wastewater biofilm treatment system, with the coarse screen inlet chamber, the suction pump station, the fine screen inlet chamber, the sand trap, the BAF pool and the clean water tank connected in series with the wash pump positioned between the BAF pool and the clean water tank, characterized in that also an anoxic denitrification pool for upstream denitrification of the effluent and a pitch tube primary clarifier for the solid-liquid separation of the effluent between the BAF pool and sand trap are set up, the inclined tube primary clarifier comprising the waste water outlet and the sludge outlet, wherein the waste water outlet is connected to the BAF pool through a center suction pump and to the sludge storage and sludge dewatering space through the sludge outlet.
Description
Technisches GebietTechnical area
Das vorliegende Gebrauchsmuster betrifft ein neues Biofilmbehandlungssystem für städtisches Abwasser. The present utility model relates to a new urban wastewater biofilm treatment system.
Technischer HintergrundTechnical background
Bisherig sind die verschiedene Belebtschlammverfahren immer noch hauptverfahren in städtischen Kläranlagen Chinas. Mit der Verbesserung der Qualitätsanforderungenan Wasser-Umgebung durch das Land wird die Qualität des abgelassenen Wasser aus den Kläranlagen in die wichtigen Gewässer gefordert, den Standard-Avon “Norm für Schadstoffemissionen von städtischen Kläranlagen" (
Inhalt der ErfindungContent of the invention
Es ist das Ziel des vorliegenden Gebrauchsmusters, ein neues Biofilmbehandlungssystem für städtisches Abwasser zur Verfügung zu stellen, um die vorstehenden Probleme zu lösen. It is the object of the present utility model to provide a new biofilm urban wastewater treatment system to solve the above problems.
Um das vorstehende Ziel zu erreichen, verwendet das vorliegende Gebrauchsmuster die folgende technische Lösung: Ein neues Biofilmbehandlungssystem für städtisches Abwasser, wobei die Zulaufkammer mit Grobsieb, die Saugpumpestation, die Zulaufkammer mit Feinsieb, der Sandfang, der BAF-Pool und der Reinwasserbehälter in Reihe miteinander verbunden sind, und wobei die Waschpumpe zwischen dem BAF-Pool und Reinwasserbehälter aufgestellt ist, außerdem ein anoxischer Denitrifikation-Pool zur vorangestellte Denitrifikation des Abwassers und ein Schrägrohr-Vorklärbecken für die Fest-Flüssig-Trennung des Abwassers zwischen BAF und dem Sandfang aufgestellt sind, wobei das Schrägrohr-Vorklärbecken den Abwasserauslass und den Schlammauslass umfasst, wobei der Abwasserauslass durch eine Mittelsaugpumpe mit dem BAF-Pool und der Schlammauslass mit dem Schlammspeicher und Schlammentwässerungsraum verbunden ist.In order to achieve the above object, the present invention utilizes the following technical solution: A new urban wastewater biofilm treatment system, with the coarse screen feed chamber, the suction pump station, the fine screen inlet chamber, the sand trap, the BAF pool, and the clean water tank in series where the washing pump is located between the BAF pool and the clean water tank, an anoxic denitrification pool for the upstream denitrification of the waste water and an inclined tube primary clarifier for the solid-liquid separation of the effluent between the BAF and the sand trap; wherein the slant pipe primary clarifier comprises the waste water outlet and the sludge outlet, the waste water outlet being connected to the BAF pool by a center suction pump and the sludge storage and sludge dewatering space to the sludge outlet.
Im Vergleich zu vorhandenen Techniken hat das vorliegende Gebrauchsmuster folgende Vorteile: durch die verstehenden Behandlungen kann die Wasserqualität der Ablassung aus den Kläranlagen erheblich verbessert wird, wobei der Gesammtstickstoffgehalt reduziert und die Wasserreinigungswirkung besser wird, wobei der Wasserauslauf auch mit dem UV-Desinfektionskanal verbunden ist, wodurch die ursprüngliche Chlordesinfektion verändert wird, damit das austretende Wasser durch die UV-Bestrahlung in bestimmenter Dosis und Intensität desinfiziert wird, um den Zweck der Reinigung zu erreichen. Compared to existing techniques, the present utility has the following advantages: the treatments under discussion can significantly improve the water quality of the discharge from the treatment plants, reducing the total nitrogen content and improving the water purification effect, the water outlet being also connected to the UV disinfection channel, whereby the original Chlordesinfektion is changed so that the escaping water is disinfected by the UV irradiation in a certain dose and intensity to achieve the purpose of cleaning.
