Embodiment 1

[0029] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0030] The water entering the intensive sewage ecological treatment device enters the water storage tank (1) after being filtered, and a second filter is installed at the front end of the water pipe entering the water distribution perforated pipe (6) of the integrated device to filter impurities in the water and avoid lifting Pump and (3) and water distribution perforated pipe (6) orifice blockage, guarantee the normal operation of integrated device. The start-up of the electric valve meets a certain water pressure requirement of 0.04-0.1Mpa.

[0031] Turn on the lifting pump (3), water inlet valve (4) and water distribution pipe valve group (7), and adjust the opening state of some valves of the water distribution valve group (7) according ...

Embodiment 2

[0035] Turn on the lifting pump (3), the water inlet valve (4) and the water distribution pipe electromagnetic valve group (7), and adjust the partial valve opening of the water distribution electromagnetic valve group (7) according to the DO content range of the first online DO detector (2) state, adjust the reoxygenation of influent water, the DO content in the water storage tank (1) is in the middle limit threshold range of 0.8mg / L-2.2mg / L, the computer control system (18) turns on the lift pump (3) and part of the water distribution electromagnetic The valve group (7), sewage enters the purification unit from the water storage tank (1) through the outlet of the water distribution perforated pipe (6) and part of the water distribution electromagnetic valve group (6).

[0036] After the purification unit completes water distribution and distribution, close the lift pump (3) and water distribution electromagnetic valve group (7), the second online DO detector (14), online ORP ...

Abstract

The invention discloses a refined regulation and control method of an intensive sewage ecological treatment device, and belongs to the field of sewage treatment. The device comprises a water storage and distribution unit, a treatment unit and a composite parameter regulation and control system, and the composite parameter regulation and control system consists of an online dissolved oxygen (DO) detector, an online temperature detector, an online oxidation-reduction potential (ORP) detector, an online pH detector, a valve and a computer regulation and control system. The regulation and controlprecision of the sewage treatment process is remarkably improved by monitoring composite parameters such as a DO value, a pH value, an ORP value and a temperature value in the sewage in real time, a water distribution type and a circular treatment flow of a sewage ecological treatment process are constructed, and an integrated type intensive sewage ecological treatment device composed of a water storage and distribution unit and a treatment unit is formed, so as to ensure the efficient denitrification effect and stable effluent quality of the sewage ecological treatment system.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a refined control method for an intensive sewage ecological treatment device, which is suitable for a decentralized domestic sewage treatment process and achieves the goals of integration, high efficiency, low cost and less maintenance. The device and control method adopt composite water quality parameters to monitor the sewage treatment process, improve and improve the sewage ecological treatment process by finely regulating the water distribution method and the circulation treatment process to achieve a stable reoxygenation degree and dissolved oxygen content, and promote the synchronous nitrification and denitrification process. Ensure that the intensive sewage ecological treatment process is always in a high-efficiency purification and stable operation state for the treatment of total nitrogen, tri-nitrogen and organic matter in domestic sewage.
