Description

A sewage treatment device

technical field

The utility model belongs to the field of sewage treatment equipment, in particular to a sewage treatment device.

Background technique

In recent years, China's environmental protection issues have become increasingly prominent. With the increasing awareness of environmental protection, urban water environment issues have also received more and more attention. Therefore, effective sewage recycling has become an important research topic for countries all over the world. The sewage treatment process generally includes physical, chemical or biological methods in sequence. The physical process is to separate and recycle the suspended pollutants in the sewage, and the chemical process is to separate and recycle the dissolved pollutants in the sewage through chemical reaction and mass transfer. , Pollutants in colloidal state, and transform them into harmless substances. Some existing wastewater discharge plants will also build wastewater sedimentation tanks to purify wastewater and prevent wastewater pollution. However, due to the complexity of the system and high cost, it is not suitable for widespread application and increases production costs. When the water quantity and quality change, its sedimentation efficiency and effluent water quality will be significantly reduced. Therefore, it is a trend to develop a comprehensive sewage treatment equipment with good water quality treatment effect.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a sewage treatment device, which has a simple structure, good water quality treatment effect, and can realize effective recovery of sewage.

The purpose of this utility model is achieved by the following technical solutions:

A sewage treatment device, comprising a barrel body and a barrel cover. The center of the barrel cover is provided with a liquid inlet. The barrel body includes a concentric outer barrel and an inner barrel. The inner barrel is arranged inside the outer barrel, and the inner barrel is driven to rotate by a driving device. , the middle part of the inner barrel is provided with a sedimentation tank, the top of the sedimentation tank is detachably connected to the lower end surface of the barrel cover, the liquid inlet is provided with a funnel-type liquid inlet pipe, and the lower end of the liquid inlet pipe extends to the sedimentation tank In the lower part, the settling tank is provided with a perforated rectifying plate, the installation position of the rectifying plate is higher than the end of the liquid inlet pipe, and a number of overflow holes are set on the side wall of the settling tank, and the several overflowing The lowermost overflow hole in the flow hole is higher than the installation position of the rectifying plate, and the inner wall of the lower part of the inner barrel is equipped with a horizontally arranged circular plate and a filter screen, the circular plate is located below the sedimentation tank and above the filter screen, and the circular plate A plurality of first through holes are arranged on the top, no less than two second through holes are arranged on the bottom of the inner barrel, and a water outlet is arranged under the side wall of the outer barrel.

Further, the rectifying plate is concave.

Further, the upper end of the funnel-type liquid inlet device is conical.

The utility model is suitable for the treatment of sewage that removes impurities through preliminary precipitation. The sewage enters the lower part of the sedimentation tank through the liquid inlet pipe, and the impurities are deposited at the bottom of the sedimentation tank. The centrifugal force generated by the high-speed rotation of the inner barrel makes the solid particles with high density move outward and accumulate on the side wall surface of the inner barrel. The water outlet of the outer barrel flows out and collects. The device of the utility model operates for a period of time, and the magazines in the sedimentation tank and the inner barrel can be cleaned up by opening the barrel cover, so as to ensure the stable operation of the system.

The device of the utility model is simple in structure and easy to operate. Through the multi-stage sedimentation, filtration and separation of the sedimentation tank, the high-speed rotating inner barrel, the circular plate and the filter net, the effective recovery of sewage is realized, and the water quality treatment effect is good, which can be widely popularized and applied.

Detailed ways

The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Apparently, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figure 1, a kind of sewage treatment device comprises staving 1, bung 4, and the center of described bung is provided with liquid inlet 5, and described staving comprises concentric outer barrel 3 and inner barrel 2, and inner barrel 2. It is set inside the outer barrel 3, and the inner barrel is driven to rotate by the driving device. The middle part of the inner barrel is provided with a sedimentation tank 6, and the top of the sedimentation tank is detachably connected to the lower end surface of the barrel cover. The liquid inlet pipe 7, the upper end of the funnel type liquid inlet device is conical, the lower end of the liquid inlet pipe extends to the lower part of the sedimentation tank, and the rectification plate 8 with holes is arranged in the sedimentation tank, and the rectification plate is Concave shape, the installation position of the rectifying plate is higher than the end of the liquid inlet pipe, a number of overflow holes 9 are provided on the side wall of the sedimentation tank, and the bottom overflow hole in the plurality of overflow holes is higher than the rectifying The installation position of the plate, the inner wall of the lower part of the inner barrel is equipped with a horizontally arranged circular plate 12 and a filter screen 13, the circular plate is located below the sedimentation tank and above the filter screen, and the circular plate is provided with a number of first through holes 14, The bottom of the inner barrel is provided with no less than two second through holes 10, and a water outlet 11 is provided under the side wall of the outer barrel.

This device is suitable for sewage treatment that removes impurities through preliminary sedimentation. The sewage enters the lower part of the sedimentation tank through the liquid inlet pipe, and the impurities are deposited at the bottom of the sedimentation tank.
