Description

A sewage treatment device

technical field

The utility model relates to a sewage treatment device, which can purify sewage.

Background technique

Rural domestic sewage has become one of the serious environmental problems in modern society. The country's rural areas produce more than 9 billion tons of domestic sewage every year, and more than 90% of the villages have no drainage channels and sewage treatment systems, and domestic sewage is discharged at will. The wanton discharge of untreated domestic sewage seriously pollutes the rural ecological environment and directly threatens the health of farmers and the economic development of rural areas. On the one hand, untreated domestic sewage flows into surface water bodies such as low-lying rivers, lakes and ponds, seriously polluting various water sources; on the other hand, domestic sewage is also the source of disease transmission, which is likely to cause infectious diseases, Occurrence and prevalence of endemic and zoonotic diseases. Treating rural sewage can not only improve the rural living environment, but also control water pollution in river basins and eutrophication of lakes, improve the water environment, and at the same time treat reclaimed water for agricultural irrigation, alleviating the shortage of agricultural water use.

Contents of the invention

The utility model provides a simple and efficient sewage treatment device for solving the technical problems existing in the known technology.

The purpose of the present invention is to provide a simple and efficient sewage treatment device capable of purifying water quality.

The technical solution adopted by the present invention to solve the technical problems in the known technology is: a sewage treatment device, including a pool body, a sludge bucket is arranged on the bottom side of the pool body, and the bottom of the sludge bucket passes through a pipeline Connected with the sludge pump, the tank body is provided with a support frame and an aeration pipe connected to the aerator outside the pool, the support frame is separated from the sludge bucket by a certain distance, and a zeolite molecular sieve device is installed inside the support frame. The zeolite molecular sieve device is connected with the sewage pump on the upper part of the pool body.

The utility model can also adopt the following technical solutions:

The zeolite molecular sieve device includes a hollow pipe and a sieve wall made of zeolite.

The sewage pump is connected to the pipeline through the water collecting pipe, the flexible pipe and the pipe head.

The zeolite molecular sieve device and the supporting frame are two single structures.

The pool body can adopt a metal structure or a reinforced concrete structure.

The slope of the pool bottom is i=0.4%.

The advantages and positive effects of the present invention are: in the utility model, the sewage enters the pipeline inside the device through the pipe wall of the zeolite molecular sieve device. The special structure can remove ammonia nitrogen, phosphorus, organic matter and radioactive pollutants in sewage, and recover metal ions in sewage to achieve the purpose of purifying water quality.

Detailed ways

In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Please refer to Fig. 1 and Fig. 2, a kind of sewage treatment device, comprises a pool body, is provided with sludge hopper 1 on the bottom side of pool body, and the lower part of sludge hopper 1 is connected with mud discharge pump 2 through pipeline, and mud discharge pump 2. Regularly carry out sludge discharge treatment on the sludge hopper 2. A support frame 3 is placed in the pool body, and the support frame 3 is spaced from the sludge bucket 2 at a certain distance. A zeolite molecular sieve device 6 is placed in the support frame 3, and the zeolite molecular sieve device 6 and the support frame 3 are two monomers, which are convenient for disassembly and washing. The zeolite molecular sieve device 6 includes a pipeline 7 and a sieve wall made of zeolite. The hollow pipeline 7 on the zeolite molecular sieve device 6 is connected with the sewage pump 11 through a pipe head 8 , a hose 9 and a water collecting pipe 10 . The zeolite molecular sieve device 6 uses natural zeolite as raw material, which is modified and punched to make it. The material density near the inner pipe is different from that of the outer one. Due to the action of the sewage pump 11, the sewage enters the interior through the pipe wall of the zeolite molecular sieve device 6. In the pipeline 7, most of the solid matter and organic matter in the sewage are intercepted during this process. Due to the special structure of zeolite, it can remove ammonia nitrogen, phosphorus, organic matter, and radioactive pollutants in the sewage, and recover the waste water. Metal ions to achieve the purpose of purifying water quality. Zeolite is a natural, non-toxic, odorless and environmentally friendly adsorbent. my country's natural zeolite resources are very rich and cheap.

An aeration pipe 4 is arranged between the bottom of the support frame 3 and the bottom of the pool body, and the aeration pipe 4 is connected with an aerator 5 provided outside the pool body.

After the sewage enters the pool body, the aerator 5 operates, and the aeration tube 4 located at the bottom of the pool body aerates evenly, and the organic particles in the sewage are suspended due to the effect of the aeration. When the sewage pump 11 is running, due to the pressure, the sewage outside the zeolite molecular sieve enters the internal pipeline 7 through the sieve wall, and flows out of the pool through the hose 9, water collection pipe 10, and sewage pump 11. The pipe head 8 is detachable and replaceable separately, which is convenient repair. The slope of the bottom of the pool is i=0.4%, so that the large particles in the sewage can slide into the sludge bucket 1 on the bottom side, and the sludge pump 2 connected to the sludge bucket 1 through the pipeline regularly discharges the sludge bucket 1 mud.

The sewage treatment device of the utility model can be used for the follow-up treatment of sewage in farms, small and medium-sized sewage treatment plants, and can also be used for advanced treatment of sewage. In view of the current situation of fund shortage, energy shortage and increasingly serious pollution in our country, this device is especially suitable for our country. A sewage treatment device according to national conditions.
