A multi-stage energy-saving aeration ecological filter bed for sewage treatment

Abstract

The invention discloses a multistage energy-saving aeration ecological filter bed for sewage treatment. The multistage energy-saving aeration ecological filter bed includes a collection box and an ecological filter bed body; the collection box is composed of a collection box body and a water pump assembly; the ecological filter bed body comprises a sewage receiving port, a dispersing device, a first motor, a bacteria solution box, a second motor, a bacteria solution spraying device, a primary filter plate, a secondary filter plate, an aeration plate and a tertiary filter box, wherein the primary filter plate is in an inverted circular truncated cone shape, the bottom of the primary filter plate is horizontally and fixedly connected with the bottom of the bacteria solution box and is located at the middle of the ecological filter bed, the secondary filter plate is located at the lower third of the ecological filter bed, the aeration plat is located at the lower tenth of the ecological filter bed, and the tertiary filter box is externally embedded in the right side face of the ecological filter bed. In a word, the multistage energy-saving aeration ecological filter bed for the sewagetreatment can effectively improve the efficiency of sewage filter treatment, the service life of the multistage energy-saving aeration ecological filter bed is prolonged, and when water pressure is insufficient, power compensation is provided for sewage supply.

Description

technical field [0001] The invention relates to the technical field of water environment restoration, in particular to a multi-stage energy-saving aeration ecological filter bed for sewage treatment. Background technique [0002] The importance of water: Water is the source of life, a necessary condition for the existence of life and economic development, and also an important part of human tissue. The content of water in the human body reaches 70%, and the remaining 30% are solid nutrients (proteins, carbohydrates, lipids, minerals, vitamins, etc.). 60% of the water in the human body is in the cells, and 40% is in the fluid (blood, digestive juice, saliva, bile, tears, sweat, intestinal juice, gastric juice). Adults need 2.5-3 liters of water per day, of which about 1 liter is drunk directly, 1 liter is supplemented with food, and 0.5 liter is formed by human metabolism. Li Shizhen in the Ming Dynasty wrote in the Compendium of Materia Medica: "Medicine supplements are no...

Problems solved by technology

[0004] In order to solve the above problems, the patent CN201310213324.9 provides a non-powered aeration ecological filter bed, which has a simple structure and a reasonable design. However, in actual use, we found that when the sewage is discharged, the sewage is mainly concentrated in the middle of the filter screen. The utilization rate is low, the filtering effect is poor, the use efficiency is high in the middle position, and the use time is often greatly shortened. After a slightly longer use time, the treated sewage will still cause pollution to the outside world; the device uses the pressure of the impact of the water flow to inject sewage into the ecological filter. pool, to avoid the power supply, but in practical applications, we found that when the sewage discharge is less, it is difficult for the sewage to climb the device pipeline, so a new type of ecological filter bed is needed to solve the existing problems
