Description

Immobilized microbial aerated biological filter purification system

technical field

The utility model belongs to the technical field of sewage treatment, in particular to a purification system for an immobilized microbial aeration biological filter.

Background technique

Purification system refers to a system that has a certain degree of self-purification and absorption capacity for environmental pollutants. It is an agricultural ecological complex that self-purifies environmental pollutants through the physical, chemical and biological actions of agricultural soil, plants and microorganisms without exceeding the environmental capacity. The use of microorganisms to purify sewage has remarkable ecological and economic benefits. However, in the existing purification system, the dissolved amount in the sewage is low, and the dissolved amount in the sewage cannot be accurately detected, and the oxygenation time of the biological carrier is not easy to control, and the removal rate of the sewage is low.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a purification system for an immobilized microbial aerated biological filter.

The purpose of this utility model is achieved as follows: a purification system for immobilized microbial aerated biological filter, including a water inlet pipe, a pool body and a water outlet pipe, is characterized in that: the water inlet pipe and the water outlet pipe are all provided with flow control There is a filter screen in the pool body, an aeration supervisor is installed at the bottom of the pool body, a purification supervisor is arranged on the aeration supervisor, a solenoid valve is provided at the front where the purification supervisor connects with the aeration supervisor, and a purification supervisor behind the solenoid valve is installed A purification branch pipe is set, a dissolved oxygen meter and a liquid level sensor are set on the inner wall of the pool body, and a controller is set on the outer wall of the pool body.

The filter screen is arranged in parallel with the aeration main pipe.

The purification main pipe and the aeration main pipe are connected by flanges, and the purification main pipe and the aeration main pipe are vertically arranged.

The controller is connected with flow control valve, solenoid valve, dissolved oxygen meter and liquid level sensor.

The utility model has the following positive effects: the utility model can automatically detect the liquid level height in the pool body through the liquid level sensor, can make the microorganisms fully contact with the sewage, and have a better purification effect; The dissolved oxygen content of the sewage makes the biological carrier in the sewage fully oxygenated, thus greatly improving the removal rate of the sewage.

detailed description

Embodiment 1, a purification system of immobilized microbial aerated biological filter, comprising a water inlet pipe 1, a pool body 4 and an outlet pipe 11, characterized in that: the water inlet pipe 1 and the water outlet pipe 11 are both provided with flow control valves 2. The tank body 4 is provided with a filter screen 3, and the bottom of the tank body 4 is provided with an aeration supervisor 6. The filter screen 3 and the aeration supervisor 6 are arranged in parallel, and the aeration supervisor 6 is provided with a purification supervisor 8, and the purification supervisor 8 is connected to the The aeration main pipe 6 is connected by a flange, and the purification main pipe 8 and the aeration main pipe 6 are vertically arranged. A solenoid valve 7 is provided at the front where the purification main pipe 8 is connected to the aeration main pipe 6, and a purification branch pipe 9 is provided on the purification main pipe 8 behind the solenoid valve 7, and a dissolved oxygen meter 5 and a liquid level sensor 10 are provided on the inner wall of the tank body 4. , a controller 12 is arranged on the outer wall of the pool body.

In the utility model, the controller is connected with the flow control valve, the electromagnetic valve, the dissolved oxygen meter and the liquid level sensor, and the dissolved oxygen content in the sewage is detected by the dissolved oxygen meter in use, and the filling in the sewage is filled with oxygen, so that the sewage and microorganisms Complete biochemical reactions occur in an environment with abundant dissolved oxygen. Under aerobic conditions, microorganisms can completely oxidize organic matter in sewage into carbon dioxide and water, thereby achieving the purpose of sewage purification. In the utility model, the minimum flow velocity of the purification main pipe is 0.6m/s, the maximum flow velocity is 1.4m/s, the minimum flow velocity of the purification branch pipe is 1.0m/s, and the maximum flow velocity of the purification branch pipe is 2.0m/s. Air is supplied from the main aeration pipe to the purification main pipe to provide sufficient oxygen during operation. In use, the air enters the purification main pipe from the main aeration pipe, and the purification main pipe diverts the air to the purification branch pipe, and the air provides the oxygen required by the microorganisms in the sewage from the purification branch pipe, and the dissolved oxygen meter can detect the dissolved oxygen in the sewage Oxygen content, when it is detected that the dissolved oxygen content in the sewage is excessive, the controller controls the solenoid valve to reduce the output of air, when it detects that the dissolved oxygen content in the sewage is low, the controller controls the solenoid valve to increase the air output, Make microorganisms obtain sufficient oxygen, thereby improving the removal rate of sewage. The liquid level in the tank is detected by the liquid level sensor. When the liquid level is high, the flow control valve at the water inlet is controlled by the controller to reduce the inflow of sewage, and the flow control valve at the water outlet is controlled to increase the flow of sewage. When the liquid level When it is low, the flow control valve at the water inlet is controlled by the controller to increase the inflow of sewage, and the flow control valve at the water outlet is controlled to reduce the outflow of sewage, thereby regulating the liquid level of sewage in the pool and making it possible for microorganisms to contact the sewage for a sufficient time , in the purification can have sufficient time for the oxidation reaction.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Within the principle, any modification, equivalent replacement, improvement, etc. should be included in the protection scope of the present utility model.
