Diatomite reactor device

Abstract

The invention relates to a diatomite reactor device. An outer shell (1) of the device is composed of an upper octagonal column body and a lower octagonal cone body, eight supporting columns (2) are arranged on the eight corners of the outer side of the octagonal column body for supporting, gutters (9) are horizontally formed in the inner side of the upper octagonal column body of the outer shell (1) along the circumference, at least four stand columns (4) are arranged on slopes of the lower octagonal cone body of the outer shell (1), hollow cylinders (5) are fixedly connected to the top ends of the stand columns (4), the internal area defined by the stand columns (4) and the hollow cylinders (5) is a flocculation chamber (6), the external area defined by the stand columns (4) and the hollow cylinders (5) is a clarifying chamber (7), an ultrafiltration layer (20) is arranged in the clarifying chamber (7), a unit weir groove net (8) is arranged on the top of the clarifying chamber (7), a gradually-expanding guide cylinder (10) is arranged in the flocculation chamber (6), the bottom of the gradually-expanding guide cylinder (10) is connected with a water inlet pipe (11) which is connected with a pipeline mounted pump (12), sludge buckets (13) are arranged on the middle-lower portions of the slopes of the clarifying chamber (7), sludge discharging pipes (14) are connected in the sludge buckets (13), and the sludge discharging pipes (14) are connected to a sludge storage pool, and a return pipe (15) is arranged at the inner bottom of the device and connected to a biochemical pool anoxic zone. The diatomite reactor device is simple in structure, good in sewage processing effect, small in occupied space, low in investment and attractive and elegant in appearance.

Description

technical field [0001] The invention belongs to the field of sewage treatment devices, and in particular relates to diatom concentrate reactor equipment. Background technique [0002] With the development of urbanization and the improvement of people's living standards, the discharge of urban domestic sewage is increasing year by year, and the increasingly complex composition of sewage is an important source of pollution leading to the deterioration of the water environment. Therefore, urban domestic sewage urgently needs to be treated. During the "Twelfth Five-Year Plan" period, the country put forward new requirements for the discharge of urban sewage, and the discharge standard was raised from the GB18918-2002 Grade B standard to the GB18918-2002 Grade A standard. From the perspective of the current process standards, the current mature process can only treat sewage to the GB18918-2002 Class B standard. [0003] At present, domestic and foreign sewage treatment methods ...

AI Technical Summary

Problems solved by technology

The equipment used in the above two methods all suffer from high energy consumption, unreasonable structure, large cost investment and the inability to recover all pollutants at one time, not to mention the reuse of sludge. It is difficult to achieve urban sewage treatment. GB18918-2002 Class A standard

[0004] The closest existing patent ZL03219471.4, the patented technology of nano-microporous diatom concentrate water treatment equipment, occupies a large area. Due to the defects of unreasonable structure, the construction period of the pool is long, the separation of mud and water is insufficient, and the sewage is intercepted. Insufficient sludge, heavy metals, most microorganisms and other substances in the sewage will cause slag emission, resulting in foul smell during the sewage treatment process, making it difficult for urban sewage treatment to meet the GB18918-2002 Class A standard
