Embodiment 1

[0038] Sequencing batch bio-zeolite reactor construction:

[0039] Such as figure 1 As shown, the sequencing batch biological zeolite reactor includes the main body of the reactor and an automatic control system. The main body of the reactor includes 1 water inlet tank 1, 5 parallel reaction columns 2 (1#, 2#, 3#, 4#, 5#), water outlet tank 3, 1 water inlet pump 4, and 1 aeration pump 5 .

[0040] The aeration pump 5 adopts several three-way joints connected in series with a gas flow meter through a silicone hose (0.6-6m 3 / h) and the aeration solenoid valve 6-3 are connected to the air inlet 17 of the reaction column to provide oxygen for the microbial community in the reaction chamber;

[0041] The water inlet pump 4 is connected to the water inlet 15 of the water inlet tank 1 and the reaction column by connecting the water inlet solenoid valve 6-1 in series with a silicone hose connected by a three-way joint.

[0042] Such as figure 2 As shown, the reaction column 2#-...

Embodiment 2

[0058] Embodiment 2, the application of sequencing batch type biological zeolite reactor

[0059] Coking wastewater is a typical toxic, harmful and refractory industrial wastewater, containing high concentrations of ammonia nitrogen, phenols and nitrogen heterocyclic pollutants. For the problem of complex pollution in coking wastewater, it is an effective method to use complex bacterial agents for biointensive treatment. Aiming at the problem that there are many kinds of nitrogen-containing substances and high concentration in coking wastewater, a group of coking wastewater tests with impact loads were designed to investigate the treatment of sequencing batch biological zeolite reactors, and compare the treatment of bioaugmentation and filling different zeolite fillers. The impact of the effect.

[0060] The sequencing batch biological zeolite reactor adopts the above-mentioned device (the schematic diagram of the reaction device is shown in figure 1 ), add suspended activat...

Abstract

The invention relates to a wastewater treatment device, and particularly relates to a wastewater treatment device with an automatic control function, which is provided with a sequencing batch biological zeolite reactor, and an application thereof as well as a wastewater treatment method adopting the device. The wastewater treatment device integrates a biological zeolite bed and the sequencing batch biological reactor into a whole and is provided with an automatic control system. The wastewater treatment device is compact in structure; through the unique design, the automatic control system tightly linked with the technology is arranged in the wastewater treatment device; the wastewater treatment device is suitable for the treatment of industrial wastewater with the relatively high concentration of nitrogen substances; the wastewater treatment device has the advantages of automatically working according to set procedures, having strong nitrogen compound resistance capacity and fully degrading organic compounds difficult to degrade.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a sewage treatment device with an automatically controlled sequencing batch biological zeolite reactor; the invention also relates to the application of the treatment device in sewage treatment and the sewage treatment device using the The treatment method belongs to the technical field of sewage treatment. Background technique [0002] Sequencing batch activated sludge process for sewage treatment is a batch-operated activated sludge process that completes different processes such as water inflow, reaction, precipitation, drainage and idleness in a sequence batch reactor. It has the advantages of space saving, strong impact load resistance, and the alternating state of anaerobic and aerobic in the system creates good environmental conditions for nitrogen and phosphorus removal. But the system also has some deficiencies, such as sludge loss easily caused by drainage, low content of d...
