Abstract

Inventia se refera la epurarea apelor reziduale, si anume la o instalatie pentru prelucrarea anaeroba a borhotului de la vinificatie, care se formeaza in urma distilarii si contine compusi organici stabili. Instalatia consta dintr-un bioreactor si un electrolizor amplasat pe acesta. Electrolizorul include un corp de forma cilindrica (14) executat din material nemagnetic si unit cu bioreactorul printr-o conducta coaxiala de transvazare (15), pe suprafata interioara a corpului (14) este amplasat un electrod (24) din aliaj de titan, conectat la polul negativ al unei surse de curent continuu, iar pe capatul superior al conductei de transvazare (15) este fixata o insertie cilindrica (23) din material izolator si un electrod concentric din otel inoxidabil (22), conectat la polul pozitiv al sursei de curent continuu, in interiorul corpului (14) pe o plasa (20) sunt amplasate corpuri (21) metalice cilindrice din material magnetic moale, un capac cu suprafata ondulata (25), iar in partea de sus este fixata o lampa UV (18) cu reflector (19). Corpul (14) de asemenea este dotat cu un racord (2) de debitare a borhotului cu ventil (3), sistem de ejectie (4) si intrare tangentiala (5), de partea exterioara a corpului (14) este amplasat un inductor (16) de camp magnetic rotitor, conectat la un regulator de tensiune (17) si la o sursa de curent alternativ. Bioreactorul include un corp (1) cu baza conica, in interiorul caruia este amplasata o incarcatura rigida (9) cu un strat de biomasa fixata, totodata corpul (1) este dotat cu un racord (6) pentru evacuarea lichidului tratat cu hidrosifon (7) si cu racord (8) pentru aer, un racord (10) pentru evacuarea sedimentului cu ventil (11), precum si cu un racord (12) pentru evacuarea biogazului cu inchizator hidraulic (13).The invention relates to wastewater treatment, namely to an installation for the anaerobic processing of the vinegar from the vinification, which is formed after distillation and contains stable organic compounds. The installation consists of a bioreactor and an electrolyser located on it. The electrolyser includes a cylindrical body (14) made of non-magnetic material and joined to the bioreactor by a coaxial transfer pipe (15), on the inner surface of the body (14) is placed an electrode (24) of titanium alloy, connected at the negative pole of a DC source, and on the upper end of the transfer pipe (15) is fixed a cylindrical insert (23) of insulating material and a concentric stainless steel electrode (22), connected to the positive pole of the source. continuous current, inside the body (14) on a net (20) are placed cylindrical metallic bodies (21) of soft magnetic material, a cap with a corrugated surface (25), and at the top is fixed a UV lamp (18) with reflector (19). The body (14) is also provided with a connection (2) for cutting the stem with a valve (3), an ejection system (4) and a tangential input (5), on the outside of the body (14) an inductor is located ( 16) magnetic rotating field, connected to a voltage regulator (17) and to an AC source. The bioreactor includes a body (1) with conical base, inside which is placed a rigid load (9) with a layer of biomass fixed, at the same time the body (1) is equipped with a fitting (6) for the discharge of the liquid treated with hydrosiphon (7). ) and with a connection (8) for air, a connection (10) for draining sediment with a valve (11), as well as a connection (12) for evacuating biogas with a hydraulic lock (13).
