Description

Technical Field

[0001] The present invention belongs to the technical field of aquaculture wastewater treatment control, and particularly relates to a high-efficiency multi-stage treatment device for livestock and poultry breeding polluted wastewater. Background Art

[0002] A large amount of breeding wastewater will appear during the livestock and poultry breeding process, including feces, manure water, flushing wastewater, etc. If the wastewater is directly discharged into natural water bodies, it will cause serious pollution to the water bodies; According to GB18596-2001 "Discharge Standards for Pollutants from Livestock and Poultry Breeding Industries", this standard is applicable to the discharge management of wastewater and sewage from livestock and poultry farms and breeding areas, and stipulates different scales of livestock and poultry breeding industries, respectively stipulating the maximum allowable daily average discharge concentrations of water pollutants and odor gases, the maximum allowable drainage volume, the harmless environmental standards for livestock and poultry breeding residues, and the wastewater needs to be treated physically, chemically or biologically to ensure compliance with the discharge standards;

[0003] Among them, the industry standard HJ / T 81-2001 "Technical Specifications for Pollution Prevention and Control of Livestock and Poultry Breeding Industries" also indicates and stipulates technical requirements such as manure cleaning processes, livestock and poultry manure storage, and sewage treatment; Before wastewater discharge, it should comply with the "Discharge Standards for Pollutants from Livestock and Poultry Breeding Industries", and purification treatment must be carried out, including mechanical, physical, chemical and biological treatment methods, and further including treatment methods such as grid filtration, anaerobic treatment, and sedimentation treatment;

[0004] After searching for the existing technologies for livestock and poultry wastewater treatment, it is found that a treatment device for livestock and poultry breeding wastewater with the publication number of CN212532642U includes a pretreatment unit, an enhanced biochemical treatment unit, and a sludge disposal unit connected in sequence. The pretreatment unit includes a grid tank, a manure collection tank, a solid-liquid separator, a flocculation sedimentation tank, and an adjustment tank connected in sequence; This solution provides a complete process for treating breeding wastewater.

[0005] After searching again, the prior art announcement number is CN209428306U. The solid-liquid separation device and feces treatment equipment provided by the utility model are disclosed. During use, the water inlet is opened, the water outlet and the mud outlet are closed, and the feces are passed into the separation tank from the water inlet. The doser adds flocculant to the inside of the separation tank, and then the stirring mechanism mixes the flocculant and feces evenly, and the solids are precipitated to the bottom of the separation tank. Then the water outlet is opened to discharge the liquid in the separator, and the mud outlet is opened to discharge the precipitated solids. However, a simple stirring impeller is used in the stirring mechanism of the above scheme for stirring. During the stirring process, the stirring effect can only be achieved for the wastewater around the impeller and at the same layer as the impeller. In order to improve the stirring effect, a large number of impellers can be set up and set up in sequence up and down to achieve mixing of the internal water body. However, the interaction effect for the upper and lower layers of the water body is still poor, and the horizontal direction is much greater than the interactive mixing of the water body in the up and down directions. In addition, there is also a disadvantage that the flocculant cannot reach the bottom of the water body in time.

[0006] According to the above search results and livestock and poultry wastewater treatment standards and regulations, the present invention provides an integrated livestock and poultry wastewater treatment device. Summary of the invention

The residual flocs on the first sector plates are pushed out by the push rod following the rotation of the second sector plates.

[0019] Furthermore, a support shaft is provided on the mounting block in the mixing mechanism arranged above, and the end of the support shaft is arranged in the groove. The up and down adjustment of the ring body drives the mixing mechanism to adjust up and down to achieve up and down adjustment of the mixing depth. When the wastewater does not fill the tank or is less, it can move downward and cooperate with the mixing mechanism below to achieve relative concentration of mixing force, thereby improving the mixing effect.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1) After the filtered aquaculture wastewater, feces, and feces water are filtered, the third electric push rod pushes the bottom plate up and cooperates with the cover plate to compress the feces water and feces, further improving the filtering and solid-liquid separation effects; then the first electric push rod pulls the cover plate to slide along the guide rail to open the top of the filter bin, and the third electric push rod continues to push out, using the bottom plate to push the compressed feces and debris out of the filter bin, and then the first electric push rod pushes and resets the cover plate, and the pushed debris and feces can be pushed to one side through the push plate on the cover plate, and enter the fermentation box along the guide plate for collection and storage; when there are a lot of debris and feces in the filter bin, the third electric push rod can be pushed out and the first electric push rod can be pushed multiple times and in small quantities to avoid the first baffle and the second baffle from failing to form an effective guiding and blocking effect;

[0022] 2) The flocculation mechanism purifies the turbid wastewater after filtration through flocculation. First, the flocculant is added to the tank through the feeding pipe; then the first motor drives the main shaft to rotate, and then drives the mixing mechanism to rotate to mix the wastewater and the flocculant;

[0023] During the mixing process, the mixing mechanism causes the first fan plate to rotate in water through the water resistance, driving the first rotating shaft to rotate. Then, through the chain, it drives the second rotating shaft to rotate. On the premise that the main shaft rotates, the rotation of the second rotating shaft will use the second fan plate to stir the wastewater upward, enabling the mixing of the water body in the up and down directions. At the same time, in cooperation with the rotation of the first fan plate around the first rotating shaft, the horizontal mixing of the water body is achieved. Further, in cooperation with the rotation of the mixing mechanism around the main shaft, the water body can be mixed in the up and down and horizontal directions, enabling the wastewater to be mixed in multiple directions, which is conducive to the mixing of the flocculant and the wastewater body, accelerating the flocculation process, and improving the treatment efficiency of the wastewater;

[0024] Furthermore, after the supernatant is extracted and the flocculants are processed, by opening the observation port, the insertion shaft can be controlled to be pulled so that one end of the insertion shaft is disengaged from the socket of the turntable. Then, the turntable can be rotated or the second fan plate can be directly rotated to adjust the angle of the second fan plate. Then, under the action of the spring, the insertion shaft is pushed to reset and inserted into the socket on the turntable for locking, preventing the second fan plate from changing during the mixing process. Finally, by adjusting the inclination angle of the second fan plate, the upward stirring force and effect on the wastewater are adjusted;

[0025] 3) Further, the mixing mechanism provided above can also be adjusted in height through a control mechanism. The second motor drives the lead screw to rotate, which in turn drives the ring body to move up and down along the inner wall of the tank. Thus, in cooperation with the support shaft, the mounting block is driven to move up and down, realizing the up and down movement of the mixing mechanism. Then, when there is less wastewater in the tank, it can be controlled to move downward, making the upper and lower groups of mixing mechanisms closer to each other, thereby concentrating the mixing force and improving the mixing rate and effect;

[0026] 4) Finally, after the mixing is completed, the rotation of the main shaft is stopped. The second electric push rod drives the first fixing plate and the end of the water suction pipe to move up and down to suck the supernatant. The situation of the supernatant and the suction pipe can be observed through the transparent sealing plate at the observation port. Then, the flocculants are discharged through the discharging mechanism;

[0027] The third motor drives the annular rack to move, which in turn drives the second shutter to rotate around the central axis. As a result, the second sector plate and the first sector plate gradually partially overlap, opening the closure of the leakage groove. The flocculants flow out along the chute and are discharged through the feeding pipe. During this process, the second sector plate drives the push rod to move on the first sector plate, scraping off the residual flocculants accumulated on the first sector plate to avoid omission and making the discharge of the flocculants cleaner.
