Description

Cielom je riešiť efektívnejšie čistenie odpadových vůd, najma anaeróbnym biologickým procesom. Náplň pozostáva z najmenej jednej tvarovky z vypalovaného silikátu. Tvarovka má celkový tvar hranola alebo kosého hranola a je opatřená otvormi a/alebo žliabkami rovnoběžnými s pozdlžnou osou tvarovky, pričom plocha otvorov a/alebo žliabkov k ploché čela tvarovky je vo vzájomnom pomere od 1 : 1,5 do 1 : 5.

Vynález sa týká náplně pre biologický reaktor na čistenie odpadových vod komunálnych, priemyselných a pofnohospodárskych.The invention relates to a charge for a biological reactor for the treatment of municipal, industrial and agricultural waste water.

Technológia anaeróbneho vyhnívania ka lu z městských čistiarní odpadových vod v tzv. ideálne miešaných reaktoroch spravidla s miešaním vyvinutým kalovým plynom je dobré známa, jej uplatnenie pre vysoko zatažené odpadové vody, najma s nízkým podielom nerozpustných látok je obtiažne až nemožné preto, že pri vysokom hydraulickom zatažení danom ikratšou dobou zdržania sa metanogénne baktérie z reaktoru vyplavujú. Dlhšie doby zdržania by viedli k stavbě ekonomicky neúnosných nádrží Preto holi vyvinuté reaktory, v ktorých sa koncentrácia metanogénnych baktérií zvyšuje vytvořením kalového mraku vo vznose a fluidnou filtráciou sa zabraňuje ich úniku. Jedným z takéhoto typu reaktorov je tzv. anaeróbny reaktor s kalovým mrakom a vzostupným tokom, známy z anglosaskej praxe. Jeho nevýhodou je poměrně komplikovaný spůsob oddefovania vytvořených bubliniek plynu od vločiek a nutnost presne udržiavať hydraulické poměry v reaktore. Funkčně ekvivalentně sú reaktory, v ktorých sa metanogénne baktérie fixujú na nosič, čím sa zabraňuje ich vyplavovaniu. Ako nosič sa osvědčili najma náplně z roznych plastov s velkým povrchom, ale tieto sú poměrně drahé a adhezia batérii na hladký nemodifikovaný povrch je spravidla slabá. Tiež sa osvědčili porézně vypalované silikátové materiály, ale žiaden známy tehlový prefabrikát nesplňa specifické požiadavky, kladené na náplň reaktora.The technology of anaerobic digestion of sludge from urban waste water treatment plants in so-called ideally stirred reactors, usually with stirring developed by the sludge gas, is well known, its application for highly overflowed waste water, especially with low insoluble matter is difficult or impossible because Under a given shorter residence time, the methanogenic bacteria are washed out of the reactor. Longer residence times would lead to the construction of economically intolerable tanks. Therefore, reactors have been developed in which the concentration of methanogenic bacteria is increased by the formation of a sludge cloud in the hive and by fluid filtration to prevent leakage. One such type of reactor is the so-called anaerobic reactor with sludge cloud and ascending flow, known from Anglo-Saxon practice. Its disadvantage is the relatively complicated method of separating the formed gas bubbles from the flocs and the necessity to precisely maintain the hydraulic conditions in the reactor. Functionally equivalent are reactors in which the methanogenic bacteria are fixed to a carrier, preventing their leaching. In particular, cartridges of various large surface plastics have proved to be suitable, but these are relatively expensive and the adhesion of the battery to a smooth, unmodified surface is generally poor. Porous fired silicate materials have also proven useful, but no known precast brick meets the specific requirements imposed on the reactor charge.

•Nevýhody popísaného stavu do značnej miery odstraňuje náplň pre biologický reaktor na čistenie odpadových vod pozostávajúca z najmenej jednej tvarovky, podlá vynálezu.The drawbacks of the described state are largely eliminated by the charge for a biological wastewater treatment reactor consisting of at least one fitting according to the invention.

Podstata vynálezu spočívá v tom, že tvarovka má celkový tvar hranola alebo kosého hranola a je opatřená otvormi a/alebo žliabkami rovnoběžnými s pozdížnou osou tvarovky. Plocha otvorov a/alebo· žliabkov k ploché čela tvarovky je vo vzájomnom pomere od 1:1,5 do 1 : 5. Steny tvarovky, otvorov a žliabkov sú s výhodou opatřené vrúbkovaním rovnoběžným s pozdížnou •osou tvarovky.SUMMARY OF THE INVENTION The fitting of the invention is characterized in that the fitting has the overall shape of a prism or an oblique prism and is provided with openings and / or grooves parallel to the longitudinal axis of the fitting. The area of the holes and / or grooves to the flat face of the fitting is in a ratio of from 1: 1.5 to 1: 5. The walls of the fitting, holes and grooves are preferably provided with a notch parallel to the longitudinal axis of the fitting.

Je výhodné, alk čelo tvarovky·, ktorá má tvar kosého hranola, zviera s pozdížnou osou tvarovky ostrý uhol A do 15°.Advantageously, the alk face of the fitting, which has the shape of a prism, forms an acute angle A of up to 15 ° with the longitudinal axis of the fitting.

Je tiež výhodné, ak sú dve susediace, alebo náprotivné steny tvarovky plné a dve opatřené žliabkami.It is also advantageous if the two adjacent or opposite walls of the fitting are solid and two are provided with grooves.

V případe, že je tvaroviek viac, sú uložené tak, že ich otvory, resp. žliabky tvoria v reaktore pozdížné dutiny.In case there are more fittings, they are arranged so that their holes, respectively. grooves form longitudinal cavities in the reactor.

Příklady prevedenia náplně podl'a vynálezu sú znázorněné na připojených výkresoch. Prvé tri obrázky sú kreslené v axonometrickom pohlade, kde na obr. 1 je znázorněný příklad prevedenia prvku náplně, na obr. 2 iný příklad a na obr. 3 detail vrubkovania. Obr. 3 v řeze demonstruje Ikombináciu dvoch prvkov ďalšieho· typu a obr. 5 ukazuje schematicky půdorys kladenia jednotlivých prvkov.Examples of embodiments of the cartridge according to the invention are shown in the accompanying drawings. The first three figures are illustrated in an axonometric view, in which Fig. 1 shows an example of an embodiment of a cartridge element, Fig. 2 shows another example, and Fig. 3 shows a detail of the notching. Giant. 3 shows in cross-section the combination of two elements of another type and FIG. 5 shows schematically a plan view of the laying of the individual elements.

Na obr. 1 je nakreslená tvarovka 1, tvořená hranolom, opatřená deviatimi otvormi 2 štvorcového prierezu, rovnoběžnými s pozdížnou osou tvarovky 1. Vrubkovanie 4 na stěnách tvarovky 1 i otvorov 2 je znázorněné šrafovanlm.FIG. 1 shows a prism shaped fitting 1 provided with nine openings 2 of square cross-section parallel to the longitudinal axis of the fitting 1. Notching 4 on the walls of the fitting 1 and the openings 2 is shown by hatching.

Obr. 2 znázorňuje len jedno čelo 6 tvarovky 1, ktorá je v tomto případe opatřená nielen otvormi 2, ale tiež žliabkami 3 v počte pat na dvoch susedných stěnách 5.Giant. 2 shows only one face 6 of the fitting 1, which in this case is provided not only with openings 2, but also with grooves 3 in the number of heels on two adjacent walls 5.

Na obr. 3 je rozkreslený detail vrubkovania 4, rovnoběžného s pozdížnou osou tvarovky 1.Fig. 3 shows a detail of a notch 4 parallel to the longitudinal axis of the fitting 1.

Na obr. 4 je demonštrovaný iný příklad prvku náplně v řeze A—A‘, kde sú usporiadané dve tvarovky 1 v tvare kosého· hranola, u ktorých ich pozdížná osa zviera so zvislicou ostrý uhol A. Na řeze tvarovky 1 sú zřejmé tri otvory 2.Fig. 4 shows another example of the filling element in section A-A ', where two prism-shaped fittings 1 are arranged in which their longitudinal axis of the animal has a vertical acute angle A. On the cross-section of the fitting 1, three openings 2 are apparent. .

Obr. 5 schematicky znázorňuje v půdoryse klad štyroch tvaroviek 1. Každá je opatřená deviatimi otvormi 2 a siedmimi žliabkami 3, pričom tvarovky 1 sú orientované tak, že plná stená 5 jednej tvarovky 1 je vždy orientovaná ku stene 5 susednej tvarovky 1, opatrenej žliabkami 3.Giant. 5 schematically shows a plan view of four fittings 1. Each is provided with nine openings 2 and seven grooves 3, the fittings 1 being oriented such that the solid wall 5 of one pipe 1 is always oriented towards the wall 5 of the adjacent pipe 1 provided with grooves 3.

Výhody náplně podl'a vynálezu sú viaceré, prvá spočívá v tom, že náplň je lačná. Tvarovky z tehloviny sú spůsobilé k hromadnej výrobě. Na vefkom poréznom povrchu sa metanogénne baktérie pevne uchytia, takže nie sú z reaktora vyplavované ani pri vysokých rýchlostiach prúdenia. Prvky náplně možno do reaktora 1’ahko instalovat bez pojivá.The advantages of the cartridge according to the invention are numerous, the first being that the cartridge is fasting. Brick fittings are suitable for mass production. Methanogenic bacteria are firmly attached to the large porous surface so that they are not washed out of the reactor even at high flow rates. The charge elements can be easily installed in the reactor 1 'without binder.

Vynález sa uplatní pri čistění odpadových vod komunálnych, priemyselných a polnohospodárskych a pri štabilizácii kalov, predovšetkým pri anaeróbnych procesoch.The invention is applicable in the treatment of municipal, industrial and agricultural wastewater and in the stabilization of sludge, in particular in anaerobic processes.
