Problems solved by technology

At present, there are still some problems in the treatment technology and equipment for this type of sewage: (1) The equipment is not very specific
Restricted by traditional technology and design concepts, many complete sets only focus on COD and BOD 5 Such as the removal of organic matter, while ignoring the removal of nitrogen and phosphorus, resulting in the quality of the effluent water from the device mostly failing to meet the functional requirements of the receiving water body, causing eutrophication; (2) Improper selection of design parameters
Although the distributed sewage is easy to degrade, the water quali

Example Embodiment

[0026] Example 1:

[0027] The structure of the multi-point water distribution and non-uniform aeration integrated sewage treatment equipment of the present invention is as follows: Figure 1~3 As shown, its cross section is circular, mainly including the internal hydrolytic acidification tank 10 and the peripheral biological filter tank 16 . The hydrolytic acidification tank 10 is a cylindrical structure, and the bottom, middle and lower parts and the upper part are respectively equipped with a water inlet pipe 1, a mud discharge pipe 5 and several water distribution pipes 2.

[0028] Described biofilter tank (16) is arranged in the clockwise direction successively with the front aerobic zone (11) that is separated into by complete partition partition (7) and half partition (8-1) left empty along the lower edge, and Sequentially by the lower edge half partition (8-1), the lower edge half partition (9-1), the lower edge half partition (8-2), the lower edge half partition (9-2...

Example Embodiment

[0030] The following is a specific example of the present invention:

[0031] A snakehead farmer owns a 2-acre breeding pond. Due to the adoption of a high-density (5000 fish / mu) breeding model, about 700m3 is discharged every week. 3 The water quality of aquaculture wastewater is as follows: SS 145±30mg / L; COD 115±25mg / L; NH 4 + -N13±6 mg / L; TN 18±8 mg / L; TP1.5±0.8 mg / L. In order to reduce the non-point source pollution caused by such aquaculture wastewater in this area and improve the water quality of aquaculture at the same time, an integrated reinforced concrete pool with a hydrolytic acidification pool and a biological filter pool was built near the aquaculture pond for integrated treatment and reuse of sewage. device, structured as figure 1 shown.

[0032] The integrated device is a cylindrical columnar structure, the effective diameter and height are 2m and 2.5m respectively, and the super height is 0.5m; the center is nested with a cylindrical hydrolysis acidificat...

Abstract

The invention provides an integrated advanced wastewater treatment device of non-uniform aeration, which is an integrated reaction tank formed by the nesting of an internal barrel and an external barrel to form sealing with underside liquid. The inner chamber of the internal barrel is a hydrolysis and acidification tank, the cavity surrounded by the walls of the internal barrel and the external barrel constitutes a biofilter; by the nesting of two barrels with different diameters, the invention forms the integrated device with the hydrolysis and acidification tank in the inner part and the biofilter at the periphery, thus leading to more reasonable functional subareas for removing solid and soluble pollutants, greatly increasing the adaptability of the device to the changes of the amount and quality of wastewater, realizing economical and high-efficiency removal of SS, COD, NH4<+>, PO4<3->, TN, TP and other pollutants, and being beneficial to the subsequent reuse of the treated water.

Description

(1) Technical field [0001] The invention relates to an integrated sewage advanced treatment device with non-uniform aeration. (2) Background technology [0002] Water pollution control technology is a branch of environmental engineering. With the shortage of water resources and the tightening of environmental standards, the advanced treatment technology of sewage, especially the deep removal technology of TN, TP, and SS, has become an important part of the current sewage treatment and reuse. Hotspots and Difficulties. At present, large-scale centralized sewage treatment is still an important way of water pollution control, but in view of its huge investment and energy loss, as well as the existence of a large number of production and domestic pollution sources that have not been included in the urban drainage system, decentralized sewage treatment and Reuse technology has become an important direction for the development of water pollution control in the future.
