Problems solved by technology

However, these devices do not make full use of the internal space to separate them, so the volume of the designed devices is relatively wasteful, and it is not suitable for use in relatively small urban families or residential areas.
[0005] The inventor has also proposed Chinese patent application 200910157951.9. Although the domestic sewage biological treatment equipment has a high degree of integration and requires a small space, for continuous water intake, treatment and water discharge, although it adopts a spherical overall design, it is different from the aforementioned sewage Like the treatment equipment, most of them use a tortuous pipeline structure inside to increase the flow area of ​​the water flow, thereby increasing the contact with the filler; however, such a pipeline structure tends to leave dead ends at the bends of the tortuous pipelines, making it difficult to rinse and clean. Moreover, it is easy to bring out the internal packing and water together when the water comes out, and it is not very convenient to load and remove the packing

Embodiment 1

[0046] Embodiment 1 water treatment equipment

[0047] like figure 1 As shown, the water treatment equipment with sludge lifting function includes a cylindrical main body container 2, a main body container 2 shell, an inlet conduit 3, an outlet conduit 5 and fillers, and wherein,

[0048] The inside of main body container 2 is divided into these three inner space parts of upper cavity 31, middle chamber 32 and lower chamber 33 by upper filter screen 34 and lower filter screen 35 from top to bottom, wherein the filter screen of upper filter screen 34 and lower filter screen 35 The pore size is smaller than the particle size of the filler, so that the filler can be restricted in the cavity 32;

[0049] The shell of the main body container 2 located at the upper part of the middle chamber 32 is provided with a recoil outlet 26 connected to the recoil outlet pipe 6, wherein the recoil outlet pipe 6 is connected to the air lifter 7;

[0050] A water inlet 23 connected to the wate...

Embodiment 2

[0059] The use of embodiment 2 water treatment equipment

[0060] Domestic sewage treatment is performed using the water treatment equipment described in Embodiment 1 of the present invention. Specifically, at first, let the domestic sewage stand for 3-8 hours, remove the floating objects, close all openings except the water inlet 23, and inject the liquid (influent COD is 241.6mg / L on average) from the water inlet 23 into the main body In the container 2, water can flow into the middle cavity 32 from the inside of the casing 36 and penetrate into the lower cavity 33 until the water surface is higher than the upper edge of the casing 36 before stopping injecting domestic sewage. Then, start the driving motor 11 to drive the screw lift rod 12 to rotate at a speed of 15 rpm, and drive the blades connected to the rotating shaft and the rotating scraper 37 to rotate, and so for 8 hours. Then, the water outlet 25 was opened to allow the internal water to flow out. The COD of the t...

Abstract

The invention provides water treatment equipment with a sludge lifting function. The equipment comprises a body container, a water inlet pipe, a water outlet pipe, a backflushing water outlet pipe connected with sludge lifting equipment, fillers and a spiral lifting system. The equipment has the following beneficial effects: the inner space of the body container of the equipment is fully utilized; buckling pipelines hardly exist in the inner space; inner circulation can be formed in the inner space to increase opportunities of contact between sewage and the fillers; the fillers can not be brought out during water outflow after the sewage is treated; and meanwhile, the fillers are convenient to fill and remove. Besides, the invention also provides a method applying the water treatment equipment.

Description

technical field [0001] The invention belongs to the field of sewage treatment. Specifically, the invention relates to a water treatment device with a sludge lifting function, which can lift the sludge washed by recoil, thereby maintaining the activity of the activated sludge and It can be used; moreover, the equipment effectively reduces the internal pipeline structure, and the space utilization is reasonable, it is not easy to cause internal blockage, it is convenient to fill and remove the filler, it can effectively backwash the filler, and it can efficiently treat domestic sewage. Background technique [0002] With the process of urbanization and the increase of population density, the treatment of domestic sewage has attracted more and more attention. In particular, our country is a country with a shortage of water resources. The per capita water resource is only a quarter of the world average (approximately 2200m 3 ). In 2006, the Chinese government issued the "Natio...
