Problems solved by technology

[0002] At present, the systems for treating industrial wastewater containing a large amount of suspended solids, urban domestic sewage, and metallurgical and chemical solid-liquid separation have problems such as large investment, high energy consumption, high operating costs, large land occupation, and difficult operation and maintenance.
The main reason is that the structure of the processing system is complex and the functions of the components are single; however, there are many supporting external devices, which are bulky and occupy a lot of land, and it is difficult to operate during operation, and the intermittent operation time is long; the safe operation rate is low; the energy consumption is high, and the operation costly

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0012] Example. Composite sewage filter, such as figure 1 Shown, comprise anaerobic tank 7, clear night pool 19 and filter tower 1, it is characterized in that: described anaerobic tank 7 is connected to the bottom of filter tower 1 by filter pump 11 and gas-water mixing valve 9 successively; Described filter tower 1 The top is connected to the clear night pool 19 through the liquid outlet pipe 16; on the liquid outlet pipe 16, in the direction from the filter tower 1 to the clear night pool 19, a flow sensor 15, a suspended matter sensor 14 and a liquid outlet valve 13 are arranged in sequence; The flow sensor 15 and the suspended matter sensor 14 are also connected to the collection end of the controller 12 , and the output end of the controller 12 is connected to the filter pump 11 . The filter...

Abstract

The invention discloses a compound sewage filter. The compound sewage filter comprises an anaerobic pool (7), a clear liquid pool (19) and a filter tower (1), and is characterized in that the anaerobic pool (7) is connected with the bottom of the filter tower (1) sequentially through a filter pump (11) and a gas-water mixing valve (9), the top of the filter tower (1) is connected with the clear liquid pool (19) through a liquid outlet pipe (16), a flow sensor (15), a suspended solid sensor (14) and a liquid outlet valve (13) are sequentially arranged on the liquid outlet pipe (16) in the direction from the filter tower (1) to the clear liquid pool (19), the flow sensor (15) and the suspended solid sensor (14) are also connected with the acquisition end of a controller (12), and the output end of the controller (12) is connected with the filter pump (11). The compound sewage filter has a compact and concise structure, few external supporting facilities, high safe operation rate and low operating cost, and can run automatically and continuously, and the filtered liquid has high quality.

Description

technical field [0001] The invention relates to a composite sewage filter, which belongs to the technical field of environmental protection. Background technique [0002] At present, the systems for treating industrial wastewater containing a large amount of suspended solids, urban domestic sewage, and metallurgical and chemical solid-liquid separation have problems such as large investment, high energy consumption, high operating costs, large land occupation, and difficult operation and maintenance. The main reason is that the structure of the processing system is complex and the function of the components is single; while there are many supporting external devices, which are bulky and occupy a large area, it is difficult to operate during operation, and the intermittent operation time is long; the safe operation rate is low; the energy consumption is high, and the operation costly. Contents of the invention [0003] The object of the present invention is to provide a co...
