Embodiment Construction

[0030] see figure 1 and figure 2 , the present invention relates to a drum type microfilter, which is mainly composed of a driving device 1, a box body 2, a casing 3, a drum 4, a flushing device 5, a microfilter 6, a liquid level detection 7, and a movable observation door 8 , Sewage tank 9, drum support device 10, flushing water pump 11 and pipeline system 12 constitute.

[0031] Driving device 1: It provides power for the rotation of the drum, adopts direct-connection driving, without intermediate transmission pair, and has a simple and stable structure.

[0032] Box 2: The box is a semi-closed structure and is the carrier of the drum. The interior is equipped with a water inlet area and a steady flow area to stabilize the shape of the water flow entering the drum and improve the filtering effect.

[0033] Cover 3: Make the whole machine in a closed structure, effectively avoid water splashing and improve the operating environment.

[0034] Drum 4: It is the micro-filte...

Abstract

The invention relates to a revolving drum type micro-filter. The revolving drum type micro-filter comprises a driving device (1), a box body (2), a housing (3), a revolving drum (4), a flushing device (5), a micro filtering net (6) and a dirt discharging groove (9). According to the method for processing sewage, sewage can flow into the hollow revolving drum, due to the action of gravity, the liquid flows towards the outer side of the filtering net from the inner side of the filtering net, and suspended matter in the water is intercepted on the inner side of the stainless steel filtering net; the revolving drum revolves slowly, a flushing water pump of the flushing device extracts the filtered water to conduct back flushing on the filtering net, the flushing water is used for flushing the filtering net from the outer side of the filtering net to the inner side of the filtering net through a nozzle of the flushing device located on the top of the revolving drum, and particulate matter which is flushed away is collected through the dirt discharging groove and is discharged out of the micro-filter through a sewage pipe. The micro-filter is simple and small in structure, small in occupied area, good in treatment effect, convenient to maintain, low in unit treatment cost and more environmentally friendly compared with other filtering devices.

Description

technical field [0001] The invention relates to a new type of solid-liquid separation equipment, in particular to a rotary drum microfilter and a sewage treatment method, which can effectively reduce suspended solids (SS) in sewage, and is applicable to various types of The treatment of sewage can also improve the purity of relatively pure water, such as upgrading and renovation projects of sewage treatment plants. Background technique [0002] Compared with the disc vacuum filter, the rotary drum filter has a larger volume, a smaller filtration area, and a lower unit processing capacity, but it has good sealing performance, high vacuum, long drying area, and low moisture in the filter cake. Drum vacuum filters for handling fine and sticky materials can be divided into two types: inner filter type and outer filter type. Due to the difficulty of removing the filter cake of the inner filter type, most of them are now of the outer filter type. According to the internal struct...
