Abstract

The invention relates to an integrated sewage treatment device which mainly comprises a pond body, a water inflow distributing device, an aerating device, an air-water separator, a solid-liquid separating device and a discharged water collecting device, wherein the aerating device, the air-water separator and the solid-liquid separating device are integrated in one pond as the core of the device, the pond is divided into an anaerobic organism zone, a facultative anaerobic organism zone, an aerobic organism zone, an air-water separation zone and a solid-liquid separation zone, and sewage is purified after sequentially passing through the anaerobic organism zone, the facultative anaerobic organism zone, the aerobic organism zone, the air-water separation zone and the solid-liquid separation zone.

Description

A kind of integrated form waste disposal plant

Technical field:

The present invention relates to a kind of integrated form waste disposal plant, belong to the water technology category.

Background technology "

At present, it is main technology and device that nearly all organic industrial sewage, sanitary sewage all adopt biological treatment, and most representative technology is A ²/ O, oxidation ditch and SBR and improved technology thereof, A ²/ O is a kind of more traditional technology, application historical long, and also relatively success, but its shortcoming is to need sludge reflux pump, and the mud quantity of reflux is big, energy consumption is high, and is wayward, and the reaction tank biological concentration is not high, and initial cost is big, and working cost is higher; The oxidation ditch process structure is simpler, moves more stablely, but general requirement is than long residence time, and biologically densely crosses not highly, and gross investment and working cost are all than higher; SBR and improved technology thereof are a kind of tempo technology faster, its biological respinse, solid-liquid separation are finished in a pond, can realize anaerobism, aerobic, solid-liquid separation function, biological concentration height in the reaction tank, decontamination effect improving and stability are fine, do not need the mud refluxing unit that biological sludge almost completely is utilized, but this class technology is owing to be intermittent operation, utilization rate of tank volume is low, need the wetting system of straining of more complicated, surplus sludge volume is bigger, and the dephosphorization denitrogenation function is not as A ²/ O technology.

Summary of the invention

In order to overcome the deficiency that exists in the above-mentioned sewage treatment process, the invention provides a kind of integrated form sewage treatment process device, its existing A ²The advantage of/O and SBR and improved technology, there is not their shortcoming and defect again in the while.

The technical solution adopted for the present invention to solve the technical problems is: with aerating apparatus, air water separator, equipment for separating liquid from solid is according to hanging down to high order in a pond, the aerating apparatus bottom is the facultative anaerobe district, bottom, facultative anaerobe district is the anaerobe district, it on the aerating apparatus aerobic zone, what contact with aerobic zone on the aerobic zone is air water separator, the zone that air water separator covered is the gas-water separation district, it on the air water separator solid-liquid displacement zone, sewage at first enters the anaerobe district by the water inlet distribution device, enter the amphimicrobian district then successively, aerobic zone, the gas-water separation district, solid-liquid displacement zone, discharge by effluent collection device at last, sewage passes through anaerobism, amphimicrobian, aerobic treatment is equivalent to A ²The characteristics of/O technology, dephosphorization and denitrification effect is good, and because the effect of solid-liquid separation, isolated biological sludge is back to aerobic zone in the action of gravity next section, a part is back to amphimicrobian district and anaerobic zone, the part biological mud in amphimicrobian district is under aerating apparatus gas draw, and the effect of drainage flow lift enters aerobic zone in addition, the anaerobic zone part biological, mud enters the amphimicrobian district under the effect of drainage flow lift, so biological sludge constantly circulates through anaerobism-amphimicrobian-aerobic-amphimicrobian-anaerobic in the pond, and biological sludge almost all is utilized, dense, have SBR and follow-on advantage thereof, because anaerobic process such as whole existence, not only biological sludge concentration height, the organism good purification, and surplus sludge volume is little, does not also need to strain this class complex apparatus of hydrophone, and process unit is operation continuously, do not need the complicated biological sludge backflow facility that consumes energy, whole technological process integrates, and takes up an area of to economize, and invests relative A with working cost ²/ O, oxidation ditch and SBR and to change improved technology all low, operational management is also simpler.

The present invention has realized high decontamination effect improving thus, and high dephosphorization and denitrification effect, continuously operation, surplus sludge volume is few, occupation of land is little, reduced investment, economic operating cost, the easy purpose of operational administrative.

Description of drawings:

The invention will be further described below in conjunction with drawings and Examples.
