Description

Automatic floating foam collecting device for sewage plant

Technical Field

The invention relates to an automatic floating foam collecting device for a sewage plant, belongs to the technical field of sewage treatment application, and particularly relates to automatic treatment of foam at a water outlet of the sewage plant.

Background

The problem of water resource pollution is always a social hotspot, and a sewage treatment plant is a social municipal facility for meeting the requirement of natural purification of water, so that sewage is recycled, a large amount of water resources can be saved, and the water pollution is reduced.

The water outlet of the secondary sedimentation tank of the sewage plant and the like can generate foam around sewage treatment units. At present, for the foam, water plants are in the stage of fishing by workers, and even part of the water plants are piled up by the foam. When the organic matter of the inlet water is high, the surface tension of the water body after aeration is increased, and a large amount of foam can be formed. And the water body carries organic matters, the foam has viscosity, and if the water jump exists at the water outlet of the sewage plant, the foam is accumulated by more than half a meter.

After the aeration tank of the sewage plant, the activated sludge is aged and disintegrated, fine organic sludge particles are adhered to the foam, so that the foam is not easy to break, and the viscosity of the disintegrated activated sludge adhered to the foam is enhanced. Therefore, an automatic floating foam collecting device for a sewage plant is needed.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides an automatic floating foam collecting device for a sewage plant. The automatic floating foam collecting device for the sewage plant is placed around the water outlet, and the automatic floating foam collecting device for the sewage plant can automatically collect floating foam generated by water flow of the sewage plant. The floating foam flows into the device through the input pipe, and the foam automatically floats and coagulates to separate and decompose the micro-viscous and greasy foam. Such froth collection device has reduced manual work load, can automatic collection froth, concentrated froth. The device has low cost, excellent floating foam removing effect and no need of unpicking and washing after installation. Greatly saves the manufacturing cost, achieves good froth removal effect and reduces CO₂The production of the composite material can protect the environment and beautify the environment.

The main technical scheme of the invention is realized as follows: the diameter of the stainless steel material is 3 meters, the height of the stainless steel material is 3 meters, the opening of the top medicine feeding opening has the length and the width of 60 centimeters, the length and the width of the side standby inspection opening are 33 centimeters, and the angle of the connecting line of the bottom round platform and the axis is 60 degrees. When the water flow of the sewage plant flows into the device through the input pipe and falls into the shock absorber (4), the water flow is blocked. The foam is separated by utilizing the automatic floating and the condensation of the foam. A few foams are attached to the air bubbles of the aeration device (3) and float up to the water surface. The medicine is periodically put into a medicine feeding port (1) in the device, and the floating concentrated foam is decomposed by feeding. The sludge at the bottom is periodically pumped to a sludge tank outside the device for the next step. If the blockage occurs, the detection is carried out from the standby detection port (2).

Preferably, the upper part of the device body is cylindrical, the lower part of the device body is a conical round table and is connected with a sludge pump, the top end of the device body is provided with an administration opening, the side part of the device body is provided with an inspection opening, and the lower part of the input pipe is in a round table shape.

Preferably, the aeration device is vertically arranged and is right-angled to the body and opposite to the outlet of the shock absorber.

Preferably, the water outlet is a U-shaped outlet with a downward opening direction.

The invention has the beneficial effects that: (1) the foam at the water outlet is concentrated and concentrated, the concentrated foam is easier to treat, the cost for separating and decomposing the foam is greatly reduced, and the time, the labor and the material resources are saved; (2) blocking and sealing off odor and reducing CO₂Discharge amount, beautify and beautify the sewage plant and protect the environment nearby the sewage plant.

Detailed Description

The invention is further described with reference to the following figures and specific examples.

Example 1: as shown in figure 1, a sewage plant floats foam automatic collection device, including throwing medicine mouth 1, reserve inspection opening 2, aeration equipment 3 and bumper shock absorber 4, throw medicine mouth 1 on the main part top, the input port is in main part left side upper portion, the delivery outlet is in main part left side lower part, bumper shock absorber 4 slows down rivers after the input port is intake, 4 tops of bumper shock absorbers are the right angle with the surface of water, aeration equipment 3 arranges 4 both sides of bumper shock absorber in, the delivery outlet adopts the U-shaped form of exporting. The device is arranged at the water outlet of a secondary sedimentation tank of a water plant, and water flow passes through the device, so that floating foam accumulation caused by the relief environment, water jump and equipment fall can be automatically collected.

The working principle of the invention is as follows: with sewage factory froth automatic collection device setting near the delivery port, when sewage of sewage factory flowed into this device through the input tube, the situation fell into bumper shock absorber (4), rivers were obstructed in the bumper shock absorber lower part. The froth mixes with sewage again in the bumper shock absorber lower part, carries out a large amount of organic sludge after the decomposition, and most froth bypasses buffering bumper shock absorber baffle, floats to the surface of water along the arrow direction in fig. 1. The device separates and decomposes micro-viscous and greasy foam from sewage by utilizing the automatic floating and cohesiveness of the foam, and floats to the water surface of the device for staying and concentrating after the foam is separated from the sewage. A few foams with large self-weight float to the water surface through attaching to the air bubbles of the aeration device (3). The aeration device simultaneously ensures that most of foams stay and accumulate on the water surface to form concentrated froth. The medicine is periodically put into a medicine feeding port (1) in the device, the medicine is fed to decompose the floating concentrated foam (or the floating foam is directly fished out from the medicine feeding port), gas and a small amount of organic sludge are generated after decomposition, and the gas overflows. The residual sewage flows pass through the shock absorber partition plate and around the outflow device, so that the sludge is prevented from being taken away, and the next treatment is carried out from an output port.

A small amount of generated sludge sinks to the bottom of the device, and the sludge at the bottom is periodically pumped to a sludge groove of a sludge concentration tank outside the device for the next step. If the blockage occurs, the detection is carried out from the standby detection port (2).

While the present invention has been described in detail with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, and various changes and modifications can be made within the knowledge of those skilled in the art without departing from the spirit of the present invention.
