Clarification, denitrification and dephosphorization integrated high efficiency equipment

Abstract

The invention discloses clarification, denitrification and dephosphorization integrated high efficiency equipment which comprises an inverted cone carbon steel structure tank body, a high efficiency solid-liquid mixing system (which comprises a jet device and a gas stripping device), a flow stabilizing barrel, skirt hemline-shaped sludge baffles, radial water collection weirs, a water inlet, a drug addition port, an emptying port, a sludge discharge port, a gas inlet and a water outlet, wherein the skirt hemline-shaped sludge baffles are arranged at the middle positions of the clarification, denitrification and dephosphorization integrated high efficiency equipment; the radial water collection weirs are arranged at the top of the clarification, denitrification and dephosphorization integrated high efficiency equipment; the water inlet, the drug addition port and the emptying port are arranged at the bottom of the inverted cone tank body; and the gas inlet and the water outlet are arranged at the top of the clarification, denitrification and dephosphorization integrated high efficiency equipment. The clarification, denitrification and dephosphorization integrated high efficiency equipment has the advantages of high struvite generating efficiency, high crystallization velocity, difficulty in blockage, investment saving, capability of removing suspended matter and the like.

Description

technical field [0001] The invention relates to sewage pretreatment equipment, in particular to a high-efficiency equipment integrating clarification, denitrification and phosphorus removal. Background technique [0002] Livestock and poultry manure wastewater or some industrial wastewater has the characteristics of high concentration of nitrogen, phosphorus, and suspended solids, and requires effective pretreatment; at present, the easy-to-operate and economical pretreatment method is to generate struvite (MgNH 4 PO 4 ·6H 2 O) method, but the composition of the sewage is complex, which often leads to problems such as difficult formation of struvite, small struvite crystals that are not easy to settle, and crystals that are easy to block pipes. Failure to meet the standards will result in serious consequences. Contents of the invention [0003] The object of the present invention is: in order to overcome the above-mentioned deficiencies of the struvite generation method...
