Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an integrated device for treating domestic sewage by utilizing a hair-planted biofilm component. Background Art

[0002] With the acceleration of urbanization and the continuous expansion of population, the discharge of domestic sewage is also increasing sharply. If domestic sewage is discharged directly into the water without treatment, the polluted organic matter will decompose and rot, which will cause the dissolved oxygen in the water to be consumed and turn black and smelly.

[0003] A Chinese patent discloses a domestic sewage treatment device (authorization announcement number CN214327488U). The patent technology sets a filter screen in the filter tube, which can filter solid impurities in the sewage, sets a reaction box in the reaction tube, and the biofilms on both sides of the reaction box can react and treat the chemical and biological impurities in the sewage, thereby avoiding the chemical and biological impurities in the sewage from affecting the environment.

[0004] However, it has certain disadvantages: the biofilm it uses is distributed horizontally, so it cannot achieve aerobic and anaerobic reactions at the same time. Therefore, aerobic and anaerobic reactors need to be set up separately, the reaction space needs to be increased, and this horizontal distribution makes the contact time between sewage and biofilm shorter, which cannot improve the sewage treatment efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide an integrated device for treating domestic sewage by using a hair-planted biofilm component, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An integrated device for treating domestic sewage using a hair-planted biofilm assembly, comprising:

[0008] Domestic sewage circulation pool;

[0009] A plurality of hair-planted biofilms, wherein the plurality of hair-planted biofilms are evenly arranged above the domestic sewage circulation pool;

[0010] A fixing mechanism, wherein the fixing mechanism is installed inside the domestic sewage circulation tank, and the fixing mechanism is connected to a plurality of hair-planted biofilms;

[0011] A circulation mechanism, one end of which is connected to the interior of a domestic sewage circulation tank;

[0012] The spray mechanism is located above the multiple hair-implanted biofilms and is connected to the circulation mechanism.

[0013] As a further solution of the utility model: the fixing mechanism comprises a fixing plate, a plurality of fixing columns are evenly installed on the upper surface of the fixing plate from left to right, and a fixing rod is installed outside the fixing column.

[0014] As a further solution of the utility model: the number of the implanted hair biofilms is equal to the number of the fixing rods, and the implanted hair biofilms are installed outside the fixing rods.

[0015] As a further solution of the utility model: the circulation mechanism includes a circulation pump, a first water pipe is installed at one end of the circulation pump, one end of the first water pipe is located inside the domestic sewage circulation tank, and a second water pipe is installed at the other end of the circulation pump, one end of the second water pipe is connected to the spray mechanism.

[0016] As a further solution of the utility model: the spray mechanism includes a first connecting tube, a connecting rod is installed on the outside of the first connecting tube, and hollow columns are installed on both left and right ends of the first connecting tube, a plurality of second connecting tubes are connected through the lower surface of the hollow column, a third connecting tube is connected between the left and right second connecting tubes, and a plurality of nozzles are installed on the lower surface of the third connecting tube.

[0017] As a further solution of the utility model: the upper surface of the first connecting pipe is connected to the circulation mechanism, and the lower end of the connecting rod is installed on the right side surface of the domestic sewage circulation tank.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The hair-planted biofilm in the utility model is suspended on the outside of the fixed rod in a folded manner, and the domestic sewage is pumped out through the circulation pump in the circulation mechanism, sprayed out through the nozzle in the spray mechanism, and sprayed to the upper end of the hair-planted biofilm for treatment. When the folded suspended biofilm treats the sewage, the sewage needs to flow through the biofilm from top to bottom, so the contact area with the biofilm is large and the contact time is long, thereby improving the efficiency of sewage treatment;

[0020] When sewage flows through the biofilm, the microorganisms on the surface of the biofilm are first exposed to sufficient oxygen and nutrients. These conditions are conducive to the growth and reproduction of aerobic microorganisms, thus forming an aerobic layer; when the sewage enters the deeper biofilm, the oxygen supply almost completely disappears, forming an anaerobic environment, which is conducive to the growth and reproduction of anaerobic microorganisms, thus forming an anaerobic layer; by realizing aerobic and anaerobic reactions in the same biofilm at the same time, there is no need to set up aerobic and anaerobic reactors separately, which greatly saves biological reaction space; the existence of aerobic and anaerobic layers enables the organic matter in the sewage to be more completely decomposed and converted, thereby improving the efficiency of sewage treatment.
