Embodiment 1

[0050] A municipal sewage treatment plant with a sewage treatment capacity of 20,000 m 3 / d (cubic meters / day), the main sewage treatment process is as follows: water intake → coarse grille → lifting pump room → fine grille → grit chamber → biochemical pool (using A 2 / O process, that is, anaerobic-anoxic-aerobic method) → sedimentation tank → disinfection tank → effluent. On-line pH, COD and ammonia nitrogen detection instruments are installed on the inlet and outlet channels or pipelines of the sewage plant, and the sewage treatment biochemical pool (A 2 / O) Common instruments such as pH meter, dissolved oxygen meter, ORP meter and sludge concentration meter are set up.

[0051] refer to figure 1 As shown, in the biochemical pool (A 2 / O) can be provided with a quick analysis device for the operating state of a sewage plant, and the size of the casing 11 of the device can be, for example, length * width * height = 80 * 60 * 150cm. A sampling pump 1 , a monitoring cylinde...

Embodiment 2

[0060] Wastewater treatment station of a pharmaceutical factory, the wastewater treatment capacity is 240m 3 / d, influent COD=2875mg / L, BOD 5 =864mg / L, SS=686mg / L, ammonia nitrogen=31.1mg / L, the main sewage treatment process is as follows: water intake→grid→regulation tank→air flotation→intermediate pool→UASB pool→biochemical pool (A 2 / O)→sedimentation tank→water outlet. On-line pH, COD and ammonia nitrogen detection instruments are installed on the inlet and outlet channels or pipelines of sewage plants, and pH meters, ORP meters, biochemical Pool (A 2 / O) Common instruments such as pH meter, dissolved oxygen meter, ORP meter and sludge concentration meter are set up.

[0061] refer to figure 1As shown, a rapid analysis equipment for the operation status of a sewage plant is installed in the central control room. Mud image collector 5, microbial camera 6, data processing unit 7, uninterruptible power supply composition 8, etc.; wherein, the monitoring tube 3 is made of ...

Abstract

The invention provides quick analysis equipment for monitoring operating states of sewage treatment plants. The quick analysis equipment comprises a sampling unit, a monitoring unit, a data processing unit and a power unit. The sampling unit comprises a sample pipeline and a sampling pump; the monitoring unit comprises a monitoring barrel, a sludge monitoring device and a biological monitoring device, the monitoring barrel is used for accommodating to-be-monitored fluid, and samples in the monitoring barrel can be monitored by the sludge monitoring device and the biological monitoring device; the data processing unit is provided with stored databases, data in the databases include diversified sludge settling behavior parameters and diversified microorganism data under different natural conditions and process operating conditions, data from the sludge monitoring device and the biological monitoring device can be acquired by the data processing unit, the acquired data and the data in the stored databases are compared and processed by the data processing unit, and state reports related to the operating states of the sewage treatment plants can be generated by the data processing unit. The invention further provides a method for monitoring the operating states of the sewage treatment plants by the aid of the quick analysis equipment.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a rapid analysis device and method for the operation state of a sewage treatment plant in the field of sewage treatment plant station operation process monitoring and system analysis. Background technique [0002] With the rapid development of our country's economy and the acceleration of urbanization, the amount of urban domestic sewage and industrial wastewater has continued to increase. Domestic sewage treatment plants and enterprise wastewater treatment stations are also increasing and undertake the important task of sewage treatment. However, the quality of the operation of the sewage plant station will greatly reduce its pollution control effect. [0003] At present, the monitoring of sewage treatment plants all over the country only stays in the online monitoring of influent and effluent water quality (influent flow, COD, NH 4 -N, etc.), the monitoring of operating status ...
