Embodiment 1

[0053] In this example, using figure 1 Processing device shown.

[0054] The farmhouse catering wastewater collected through the pipe network flows into the oil separation sedimentation tank 1 by itself, and the suspended solids and oil in the sewage are initially separated by natural flotation, so as to prevent it from clogging the subsequent treatment unit and reduce the load of subsequent treatment, and then pass through The pretreated sewage enters the aerobic tank 2, and a combined film-hanging filler is set in the aerobic tank, and microorganisms are inoculated. The growth provides strong conditions and increases its contact area with the sewage. The bottom of the oxidation tank filler is directly blown and aerated, and the biofilm is directly strongly disturbed by the updraft, which renews quickly and maintains a high activity. At the same time, the influent load is stable. Under certain circumstances, the biofilm can maintain a certain thickness and is not prone to cl...

Abstract

The invention discloses a happy farmhouse wastewater treatment device and method. The device comprises an oil separation settling pond, a facultative tank, an aerobic biofilm unit and an ecological filter which are arranged in sequence; the happy farmhouse wastewater passes through the oil separation settling pond, the facultative tank, the aerobic biofilm unit and the ecological filter in sequence, and then is discharged out from the ecological filter. The device and the method, provided by the invention aim at high concentrated organic wastewater containing rich plant fiber, starch, sugar, protein, vitamin, animal fat and the like, such as happy farmhouse restaurant wastewater, connecting the processes of 'oil separation settling', 'facultative biofilm treatment', 'aerobic biofilm treatment', and 'ecological filter' in series sequentially in a separation manner, and purifying and treating agriculture product processing wastewater containing a large amount of grease and high concentrated ammonia nitrogen and total phosphorus, and the happy farmhouse restaurant wastewater.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a high-efficiency treatment of farmhouse catering waste water containing high oil, nitrogen and phosphorus, and in particular to a high-efficiency nitrogen and phosphorus removal device and method for farmhouse sewage. Background technique [0002] The current treatment methods of catering wastewater mainly include: physical chemical method (coagulation method, adsorption method, coarse graining method and air flotation method, etc.), electrochemical method (electrocoagulation, micro-electrolysis, pulse electrocoagulation method, etc.), microbial treatment method (biological contact oxidation method and sequencing batch activated sludge method), natural biological treatment method. [0003] Among the above-mentioned treatment methods, the biological method is not suitable for the vast number of small and medium catering owners due to its relatively large footprint and long residence t...
