Detailed Description
The present disclosure will now be discussed with reference to exemplary embodiments. It should be understood that the embodiments discussed are merely to enable those of ordinary skill in the art to better understand and thus practice the teachings of the present utility model and do not imply any limitation on the scope of the utility model.

The term "based on" is to be interpreted as "based at least in part on". The terms "one embodiment" and "an embodiment" are to be interpreted as "at least one embodiment.
Fig. 1 schematically shows a structural layout of an MBR membrane-buried sewage treatment apparatus according to an embodiment of the present utility model. As shown in fig. 1, in the present embodiment, an MBR membrane-embedded sewage treatment apparatus includes: the membrane type purifying tank comprises a membrane type purifying tank body 1, a sand settling tank 2 arranged in the membrane type purifying tank body, a flow regulating tank 3 arranged at intervals with the sand settling tank 2, a sludge storage tank 4 arranged at intervals with the flow regulating tank 3, a denitrification tank 5 arranged at intervals with the sludge storage tank 4, and a nitrification tank 6 arranged at intervals with the denitrification tank 5, wherein a filtering structure 7 is arranged between the sand settling tank 2 and the flow regulating tank 3, and a membrane separation device 8 is arranged in the nitrification tank 6.
In the present embodiment, the sand tank 2 deposits foreign matter having a large specific gravity such as sand and soil in the inflow water. The accumulated sundries are cleaned and removed regularly by a vacuum sewage suction truck or a submersible pump.
In the present embodiment, the filter structure 7 is a filter grid. The purpose of cleaning the surface of the filter grating is achieved by dispersing air at the bottom of the filter grating, and impurities in the sewage are removed.
In the present embodiment, a timing control device is provided in the denitrification tank 5 to intermittently perform aeration and anaerobic agitation. Specifically, the nitrified nitrate nitrogen (oxidation of ammonia nitrogen) in the nitrifying tank 6 is reduced into nitrogen gas by the action of microorganisms and released into the atmosphere, thereby removing nitrogen element in the water. The denitrification tank is in a facultative state through aeration and stirring. When BOD/N of the discharged water is less than 3, BOD sources such as methanol and sodium acetate are added to supplement the deficiency of BOD and promote denitrification (the injection equipment of the BOD sources is required to be purchased additionally). Intermittent aeration is realized by the timing control device in the tank, and anaerobic stirring is performed.
In the present embodiment, the nitrification tank 6 performs nitrification (oxidation) of ammonia nitrogen while the organic matter in the sewage is decomposed aerobically by the action of microorganisms. A part of the water in the tank is returned to the denitrification tank 5 (nitrifying liquid circulation). In addition, a flocculant (PAC) was added to the tank for phosphorus removal. The water-insoluble phosphate compound is transferred to the sludge storage tank 4 together with the surplus sludge by the action of the flocculant. The membrane is blocked, and the water is necessarily filtered and treated in an aeration state. Too much or too little air amount for aeration adversely affects the membrane separation device 8, and therefore the air amount is confirmed and adjusted.
In the present embodiment, the sludge storage tank 4 stores excess sludge from the denitrification tank 5, and is periodically cleaned and removed by a vacuum sewage suction truck and a submersible pump. In order to facilitate the operation of sludge suction, a gas dispersing pipeline for stirring is arranged in the tank.
In the present embodiment, the membrane separation device 8 performs solid-liquid separation of activated sludge (microorganisms) and treated water by an immersion type precise filtration membrane (submerged membrane) provided in the nitrification tank 6, and concentrates the activated sludge to a high concentration. Air used for cleaning is often used to clean the membrane surface, allowing long-term stable filtration to continue. The air used for cleaning can also provide oxygen for the decomposition of organic matters and the nitrification of ammonia nitrogen, and also has the function of stirring the nitrifying tank 6. In order to prevent clogging of the membrane, the treated water must be in an aerated state when filtered. Too much or too little air amount for aeration adversely affects the membrane separation device 8, and therefore the air amount is confirmed and adjusted.

As shown in fig. 2, in the present embodiment, the membrane separation device 8 includes a membrane frame 9 in which a membrane module is installed and a gas dispersing frame 10 in which a gas dispersing device is installed.
