    摘要： An anode and cathode synergistic electrocatalytic system for wastewater treatment and an application, which belong to the field of wastewater treatment. The method comprises the following steps: using an electrode having a "dual function" as a cathode (2-1), sequentially arranging same and an anode (2-2) in a crisscrossed and parallel mode and fixing same into an electrode group, and placing the electrode group in a reaction tank (2-3) which has an aeration device b (2-4) at the bottom thereof, separately connecting the cathode (2-l) and the anode (2-2) of the electrode group to a power supply (2-5), and performing electrocatalytic degradation on wastewater. In the electrocatalytic degradation process, a synergistic electrocatalytic degradation effect of the anode and the cathode is achieved by means of the mutual coordination of heterogeneous electro-fenton of the cathode (2-1) and oxidation of the anode (2-2). The cathode ad anode synergistic electrocatalytic process has a good wastewater treatment effect, high current efficiency, low energy consumption, and low operation and maintenance costs.

    摘要： Zur Phosphorrückgewinnung wird ein Klärschlamm (1) einer thermisch-biologischen Hydrolyse (2) unterworfen, um Phosphor als Phosphat aus seiner Trockensubstanz zu lösen. Die Hydrolyse (2) wird für einen ersten Zeitraum bei einem ersten pH-Wert durchgeführt. Der erste Zeitraum wird beendet, indem Zitronensäure (3) zugesetzt wird, so dass der erste pH-Wert um mindestes 0,5 auf einen zweiten pH-Wert abgesenkt wird. Bei dem zweiten pH-Wert wird die Hydrolyse (2) für einen zweiten Zeitraum fortgesetzt, der mindestens 0,5 h beträgt, aber höchstens halb so lang ist wie der erste Zeitraum. Von einem durch die Hydrolyse (2) erhaltenen Hydrolysat wird ein Schlammwasser (6) abgetrennt. Das gelöste Phosphat wird in einer MAP-Fällung (8) durch Anheben des pH-Werts und Zugabe eines Magnesiumionendonators (9) als Magnesium-Ammonium-Phosphat aus dem Schlammwasser (6) gefällt.

    摘要： Provided is a method for suppressing microorganism contamination in a water system that contains a reducing agent, the method being characterized in that a stabilized chlorine-based oxidizing agent comprising a chlorine-based oxidizing agent and a sulfamic acid compound, and/or a stabilized bromine-based oxidizing agent comprising a bromine-based oxidizing agent and a sulfamic acid compound is intermittently added to the water system so that the ratio of the time when the stabilized chlorine-based oxidizing agent and/or stabilized bromine-based oxidizing agent is not being added relative to the time when the same is being added of is 0.1 or more.

    摘要： The present invention relates to the use of a polymer as adsorption material, characterised in that the polymer comprises one or more of the moieties represented by formula (1):

            A-B     (1)

    , wherein the moieties can be the same or different,
    wherein the moieties are covalently bonded via A and/or B to the polymer backbone or other parts of the polymer;
    wherein A is
    a) an aromatic group being substituted with one or more OH- and/or SH-groups, or
    b) an aromatic group attached to B via a methylene group of the formula -[CH 2 ]- or a methylene carbanion group of the formula -[CH - ]-, or
    c) a 1,4-benzoquinone group or 1,4-naphthoquinone group being substituted in 2-position with the substituent being B and being substituted in 3-position with an OH group;

    wherein B is
    a pyridinium or benzoannelated pyridinium compound, wherein A is bonded to the nitrogen atom of the pyridinium or benzoannelated pyridinium compound. The present invention further relates to a metal complex or coordination compound comprising a metal-containing compound and said polymer, a method for selective separation of different types of metal cations and/or complex metal-containing anions using said polymer and polymerizable compounds useful for selective separation of different types of metal cations and/or complex metal-containing anions.
