Biological floating bed system

Abstract

The invention relates to a biological floating bed system. The biological floating bed system comprises a floating bed assembly, suspension filler, an aeration device, a dissolved oxygen instrument, a control device and a power supply system, wherein the floating bed assembly floats in a water body; multiple suspension filler is dispersed in the floating bed assembly; the control device is respectively connected with the aeration device and the dissolved oxygen instrument; the aeration device is provided with an aeration end part; the aeration end part is positioned in the water body under the suspension filler; the aeration device can be used for delivering air to the aeration end part and aerating the water body through the aeration end part; the dissolved oxygen instrument is provided with a dissolved oxygen probe; the dissolved oxygen probe stretches into the water body nearby the floating bed assembly; the dissolved oxygen instrument can be used for detecting the content of dissolved oxygen in the water body and feeding the content of the dissolved oxygen to the control device; the control device can be used for controlling the aeration device to aerate the water body according to the content of the dissolved oxygen in the water body. According to the biological floating bed system disclosed by the invention, oxygen supply can be automatically carried out on the water body, appropriate oxygen is supplied, and the energy is saved; the suspension filler is better in fluidization, and the contact area between the suspension filler and the water body is large.

Description

technical field [0001] The invention belongs to the field of purification of polluted water bodies, and in particular relates to a biological floating bed system. Background technique [0002] At present, in the field of purification of polluted water bodies, biological floating beds are often used as a technology for treating polluted natural water bodies. While using the biological floating bed to purify the water body, due to the consideration of the landscape problem, the soilless cultivation of aquatic plants or the combination of soilless cultivation of aquatic plants and hanging fillers is often used for treatment. However, aquatic plants are greatly affected by seasonal and temperature changes. In winter, the survival rate of aquatic plants is low, and the humic acid formed by plant decomposition will cause secondary pollution to the water body, and dead plants need to be treated when rotten aquatic plants appear. Manual salvage increases the workload of more water ...

AI Technical Summary

Problems solved by technology

However, the existing aeration device is based on the artificial monitoring of the monitor. When the purification effect is felt to be poor, the aeration device is turned on for aeration treatment, and when the purification effect is felt to be normal, the aeration device is turned off. This artificial monitoring method As a result, either the aeration time of the aeration device is too long, which wastes energy, or the aeration time is too short, which fails to achieve the purpose of improving the effect of purifying the water body

Moreover, the current aeration device only stops at controlling the switch of the aeration device, and cannot control the size of the aeration volume. Although it can improve the purification effect of the water body to a certain extent, it still cannot be used according to the needs of the water body, which is a waste of energy.

[0004] As for the selection of the energy supply system, the operating cost of electric energy alone is high, and the single solar energy or even the energy supply system with battery is used in the case of rainy weather, which cannot fully respond to the energy demand of the system.

[0005] In summary, the traditional biological floating bed system has problems such as: excess or insufficient energy supply and oxygen supply, salvage of aquatic plants and secondary pollution, small contact surface between suspended filler and water body, and inability to freely switch electrical energy.
