Description

Integrated aerobic-the anoxic waste disposal plant

Technical field

The utility model relates to a kind of sewage disposal device, and particularly a kind of combination has the integrated aerobic-anoxic waste disposal plant in multi-functional district.

Background technology

Existing sewage disposal technology has a lot, as chemical method, flocculation sedimentation, biochemical process etc., dissimilar sewage or waste waters is adopted different treatment processs.Often adopt biochemical process to handle to containing organic dirt (giving up) water, active sludge in the use device or microbial film carry out nitrated and denitrification to organic decomposition, ammonia nitrogen, remove organic pollutant and ammonia and nitrogen pollution.The most Processes and apparatus of such treatment process is complicated, initial cost is big, floor space is big, processing cost is higher, denitrification effect is relatively poor, and treating processes adopts a plurality of separate equipment separately to finish.As anaerobic-anoxic-aerobic process, each processing section separately makes up mostly, as realizing circulation, must realize by facilities such as pumps, influence because of being subjected to reflux ratio etc., and both running cost that must be higher, inaccessible again high processing effect, especially nitric efficiency are not high.

Summary of the invention

The purpose of this utility model be to overcome the shortcoming of above-mentioned prior art and provide a kind of improved integrated aerobic-the anoxic waste disposal plant, the combined integrated operation in multi-functional district, reduce and build floor space, reduce cost of investment and operation, maintenance cost, improve sewage treatment capacity and efficient.

The purpose of this utility model can realize by following technical measures: be provided with dividing plate in the housing of this device and longitudinally the housing inner chamber be separated into oxygen-starved area and aerobic zone, dividing plate is fixed on the sidewall of housing, the dividing plate upper position is provided with the cocycle window, be installed with down the circulation window between lower end and housing base plate, the cocycle window, following circulation window is communicated with the top of oxygen-starved area and aerobic zone respectively, the bottom, opening for feed is located at the aerobic zone bottom, the gas-liquid mixed injector is housed, the injector fluid flows to from bottom to top, mixed solution is under the guiding of injector fluid, flow from bottom to top at aerobic zone, and the cocycle window that passes aerobic zone and oxygen-starved area dividing plate enters the oxygen-starved area, from top to bottom mobile also warp circulation window shape down becomes circulating between aerobic zone and the oxygen-starved area, venting port is arranged on the oxygen-starved area, position, lateral middle and upper part, oxygen-starved area is provided with settling tank, settling tank and oxygen-starved area are separated by dividing plate, be installed with channel connection settling tank and oxygen-starved area between at the bottom of dividing plate lower end and the settling tank, water port is located at the settling tank side wall upper part, mixed solution enters settling bowl by the settling tank foot passage, clarifying water is discharged from water port, sedimentation mud refluxes certainly through the settling tank foot passage, mud backflow and mixed solution enter settling bowl and all use same passage, be easy in settling bowl to form the sludge suspension layer and make to form between the mud of rising mixed solution and sinking and collide, absorption and filteration, the processing efficiency of raising settling tank.

The utility model is reasonable in design, oxygen-starved area, aerobic zone and settling tank are combined in one, can constantly carry out that organism decomposes, ammonia nitrogen is nitrated and denitrogenation in each functional zone, effect is obvious, and active sludge can be cut down organic pollutant and ammonia nitrogen content in the sewage effectively from refluxing, help improving wastewater treatment efficiency and efficient, its compact construction, floor space are few, less investment, running cost are low, and adaptability is strong, is the environmental protecting device of a Nover practical.

Description of drawings

Fig. 1 is a structure iron of the present utility model;

Embodiment

With reference to Fig. 1, this device comprises housing [1], opening for feed, water port [5], venting port [8], and shell [1] is vertical tube structure, and horizontal section is circular, also can be squarely, is supported by leg [14].
