Embodiment 1

[0037] Such as Figure 1-4 As shown, the present invention provides an ecological peristaltic bed reactor, the ecological peristaltic bed reactor is a multi-stage series structure, wherein the number of stages of the series structure is seven, wherein the first, third, fifth, and seventh stages are upflow , The second, fourth, and sixth stages are downflow. And the ecological peristaltic bed reactor includes an equipment room unit 100 (with heating inside, so that the temperature of the sewage water in this device will not be lost), a greenhouse unit, a first-level pretreatment unit, a second-level biological treatment unit and a third-level advanced treatment Unit, the first-level pretreatment unit is provided with an oil separation sedimentation area 200 and a coagulation sedimentation area 300, and is provided with a water inlet pipe 1, an oil discharge pipe 14 and a first mud discharge pipe 3, and a water retaining plate is provided inside it 5 and the agitator 4, the sec...

Embodiment 2

[0043] Such as Figure 1-4 Shown, the present invention provides a kind of method utilizing described ecological peristaltic bed reactor to process waste water, comprises the following steps:

[0044] 1) According to the types of pollutants in the wastewater to be treated, fix the corresponding microorganisms (which can be B110, B111, B222, B350, B350M, purchased from the US BIO-SYSTEMS company) to different levels of biological carriers in a certain order And culture at 10°C-50°C for 10-30 days, and the dosage of microorganisms is 0.5-1kg / m 3 biological carrier;

[0045] 2) The wastewater that needs to be treated enters through the water inlet pipe of the first-level pretreatment unit through the equipment room, and is pretreated in the oil separation sedimentation area 200 and the coagulation sedimentation area 300 (removing oils, suspended solids, etc. in the water), and the effluent rises and flows freely To the secondary biological treatment unit, the scum and oil are d...

Embodiment 3

[0049] In order to verify the effect of the ecological peristaltic bed reactor in Example 2 above in treating domestic sewage in small and medium-sized cities, we conducted a comparative test at the Gaocheng Wastewater Treatment Plant in Hebei Province from July 2015 to September 2015. The processing object is urban domestic sewage, the existing peristaltic bed (patent number: CN204079731U) (test process: sewage→grid→existing peristaltic bed→up to standard discharge;) and the ecological peristaltic bed reactor described in the present invention (test Process: sewage→grid→ecological peristaltic bed reactor→standard discharge) a comparative test was carried out.

[0050] For the treatment test of domestic sewage in cities and towns, the comparison results between the existing peristaltic bed and the ecological peristaltic bed reactor of the present invention after treatment are shown in the following table 1 under the same influent water quality and the same design hydraulic rete...

Abstract

The invention relates to an ecological peristalsis bed reactor. The ecological peristalsis bed reactor comprises an equipment room unit, a greenhouse unit, a primary pretreating unit, a secondary biological treating unit and a tertiary deep treating unit, wherein an oil-insulation sedimentation area and a coagulation sedimentation area, a water pipe, an oil discharge pipe and a first sludge discharge pipe are arranged in the primary pretreating unit; a biological carrier, an aeration system, a first sludge sedimentation area and a second sludge discharge pipe are arranged in the secondary biological treating unit; a plant absorption area, a sterilizing area, a second sludge sedimentation area and a third sludge discharge pipe are arranged in the tertiary deep treating unit. To-be-treated waste water can reach the first-grade A standard after being treated by the primary pretreating unit, the secondary biological treating unit and the tertiary deep treating unit. The ecological peristalsis bed reactor has the advantages that a greenhouse is mounted at the top of a treating area, special aquatic plants are planted in the plant absorption area, aisle flower beds are designed, the temperature in the greenhouse is kept, linkage treatment by microorganisms and the plants is achieved, and integration, automation, deodorization and landscaping of waste water treatment are achieved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an ecological peristaltic bed reactor and a method for treating waste water using the same. Background technique [0002] At present, the traditional activated sludge methods for treating industrial wastewater mainly include oxidation ditch process, A2 / O process, SBR process, CASS process and contact oxidation process. The main problem of this kind of treatment process is that the water quality after treatment cannot stably meet the first-level standard of "Comprehensive Wastewater Discharge Standard" GB8978-1996. The main reason is that the activated sludge treatment process is vulnerable to changes in water quality and quantity. Once the system is damaged, it will take a long time to recover. However, the sewage source of the sewage treatment plant is continuous, and there is no condition for long-term shutdown for health maintenance. Therefore, using the traditiona...
