Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to an organic fertilizer wastewater treatment device and a treatment method. Background Art

[0002] Organic fertilizer wastewater primarily originates from wastewater generated during the production of organic fertilizers. This includes wastewater generated during the fermentation, composting, cleaning, or processing of raw materials such as livestock and poultry manure and agricultural waste. This type of wastewater typically contains high concentrations of organic matter, ammonia nitrogen, and suspended solids, and may contain pathogens, heavy metals, or salt. Direct discharge can pollute water, soil, and air.

[0003] Organic fertilizer wastewater treatment includes pretreatment, biological treatment, physical and chemical treatment and disinfection;

[0004] Among them, pretreatment is solid-liquid separation, which removes large suspended particles through screens, centrifuges or screw extruders to reduce the subsequent processing load.

[0005] Organic fertilizer wastewater contains heavy metal components. Wastewater containing heavy metal components should be treated in the pretreatment stage to prevent heavy metal components from entering farmland and causing pollution.

[0006] Wastewater from the wastewater treatment tank is treated with chemical treatment agents. Heavy metals in the wastewater react with the added chemicals to form reactants, which are then removed through solid-liquid separation. After treatment in the treatment tank, the heavy metals in the wastewater meet emission standards, and the treated wastewater can be used to irrigate farmland. However, for farmland irrigation, heavy metals in wastewater that meets emission standards can cause chronic soil pollution. Directly using this wastewater for farmland irrigation is detrimental to the long-term development of the soil.

[0007] In view of this, we propose an organic fertilizer wastewater treatment device and treatment method. Summary of the Invention

[0017] The lifting structure includes a fixed plate, and the two fixed plates are respectively fixedly arranged on the front and rear walls of the inner cavity on one side of the liquid outlet end of the channel A. Two connecting rods are symmetrically rotated at the upper and lower ends between the two fixed plates. The two ends of the connecting rods are respectively sleeved with sprockets C. A chain B is provided between the two sprockets C on the same side in the longitudinal direction. A plurality of lifting buckets are fixedly provided between the two chains B.

[0024] A method for treating organic fertilizer wastewater, the method is as follows:

[0026] S1. The organic fertilizer wastewater to be pretreated is input from the inlet end of channel A. The wastewater impacts the liquid guide plate A. The inclined liquid guide plate A guides the wastewater and cooperates with the inclined liquid guide plate B to make the wastewater flow out from the opening between the bottom ends of the liquid guide plates A and B.

[0027] S2. The directed wastewater flows obliquely toward the corresponding dispersion plates. The impact force of the water flow drives the corresponding dispersion plates to rotate, causing the drum to rotate accordingly. Multiple dispersion plates are impacted by the water flow in turn, causing the drum to rotate continuously. The liquid pump delivers the chemical treatment agent in the liquid tank into the drum. Due to pressure, the chemical treatment agent enters the dispersion plate cavity from the drum cavity through connecting pipes A and B, and is then sprayed out from the holes in the dispersion plate. The sprayed chemical treatment agent is in a swirling state due to the rotation of the dispersion plate, cooperating with the dispersion plate to disperse the wastewater, and the sprayed chemical treatment agent fully contacts and reacts with the wastewater;

[0029] S4, the wastewater then flows along the guide plate C to the top of the filter screen and then falls. After the wastewater reacts with the chemical treatment agent, it passes through the filter screen, where the reactants are separated. The reactants fall to the lower part of the filter screen through the inclined filter screen.

[0030] S5. In conjunction with the rotation of the drum, the shaft rotates relative to channel A, and sprocket A rotates accordingly. Sprocket A drives sprocket B to rotate through chain A, causing a connecting rod to rotate. In conjunction with the transmission of sprocket C and chain B, multiple lifting buckets continue to perform lifting movements. The lower lifting bucket touches the reactants at the lower part of the filter and scoops them up. After the lifting bucket filled with reactants is lifted to the top, it is thrown into the slag discharge channel. In conjunction with the slag guide plate, the reactants are discharged from the slag discharge channel.

[0031] When cleaning the filter, loosen and remove the bolts, separate channel A and channel B, separate square frame A and square frame B, and the staff clean the filter in channel B.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. The present invention has the advantages of further removing heavy metal components in the wastewater while transporting organic fertilizer wastewater and separating the reactants by arranging a rotating drum, a dispersion plate, a rotating shaft, a connecting pipe A, a connecting pipe B, a sealed bearing, a liquid pump and a liquid tank, thereby solving the problem that the residual heavy metal content in the wastewater that meets the emission standards will cause chronic pollution to the soil, and the direct use of this part of the wastewater for farmland irrigation is not conducive to the long-term development of the soil.

[0034] 2.

The liquid guide plate A1100 and the liquid guide plate B1200 are both inclined, and a height difference is formed between the liquid guide plate A1100 and the liquid guide plate B1200. The organic fertilizer wastewater to be pretreated is input from the inlet end of channel A100, and the wastewater impacts the liquid guide plate A1100. The inclined liquid guide plate A1100 guides the wastewater and cooperates with the inclined liquid guide plate B1200 to make the wastewater flow out obliquely from the opening between the bottom ends of the liquid guide plate A1100 and the liquid guide plate B1200. The guided wastewater flows obliquely toward the corresponding dispersion plate 802.

Stop bars 808 are fixedly provided on both sides of the longitudinal ends of limit plates 807. The sliding cavity formed by the two stop bars 808 and the limit plates 807 is engaged with the ends of dispersing plate 802. Due to the centrifugal force and gravity of the rotation, dispersing plate 802 cooperates with the expansion and contraction of connecting tubes A 804 and B 805, dispersing plate 802 becomes movable relative to drum 801.

Workers then clean filter screen 1300 in channel B200.

[0070] A method for treating organic fertilizer wastewater, the method is as follows:

[0071] S1. The organic fertilizer wastewater to be pretreated is input from the inlet end of channel A100. The wastewater impacts the liquid guide plate A1100. The inclined liquid guide plate A1100 guides the wastewater and cooperates with the inclined liquid guide plate B1200 to make the wastewater flow out from the opening between the bottom ends of the liquid guide plates A1100 and B1200.

[0072] S2. The directed wastewater obliquely flows toward the corresponding dispersion plate 802. The impact force of the water flow drives the corresponding dispersion plate 802 to rotate, and the drum 801 rotates accordingly. The multiple dispersion plates 802 are impacted by the water flow in turn, causing the drum 801 to rotate continuously. The liquid pump 600 delivers the chemical treatment agent in the liquid tank 700 into the drum 801. Due to pressure, the chemical treatment agent enters the inner cavity of the dispersion plate 802 from the inner cavity of the drum 801 through the connecting pipe A 804 and the connecting pipe B 805, and is then sprayed out from the holes on the dispersion plate 802. The sprayed chemical treatment agent is in a rotating spraying state due to the rotation of the dispersion plate 802, and cooperates with the dispersion plate 802 to disperse the wastewater. The sprayed chemical treatment agent fully contacts and reacts with the wastewater.

[0073] S3. Due to the centrifugal force of rotation and gravity, and in conjunction with the expansion and contraction of connecting pipes A 804 and B 805, the dispersion plate 802 becomes movable relative to the drum 801, further dispersing the sprayed chemical treatment agent.

[0074] S4. The wastewater then flows along the liquid guide plate C1400 to the upper side of the filter screen 1300 and then falls. After the wastewater reacts with the chemical treatment agent, it passes through the filter screen 1300, where the reactants are separated. The reactants then fall to the lower side of the filter screen 1300 through the inclined filter screen 1300.

[0075] S5. In conjunction with the rotation of the drum 801, the rotating shaft 803 rotates relative to the channel A100, and the sprocket A1501 rotates accordingly. The sprocket A1501 drives the sprocket B1503 to rotate through the chain A1502, causing a connecting rod 902 to rotate. In conjunction with the transmission of the sprocket C904 and the chain B905, multiple lifting buckets 903 continue to perform lifting movements. The lower lifting bucket 903 contacts the reactants at the lower part of the filter 1300 and scoops them up. After the lifting bucket 903 filled with the reactants is lifted to the top, it is thrown into the slag discharge channel 400. In conjunction with the slag guide plate 401, the reactants are discharged from the slag discharge channel 400.

[0076] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

Organic fertilizer wastewater to be pretreated is input from the inlet end of channel A (100). The wastewater impacts the liquid guide plate A (1100). The inclined liquid guide plate A (1100) guides the wastewater and cooperates with the inclined liquid guide plate B (1200) to make the wastewater flow out from the opening between the bottom ends of the liquid guide plate A (1100) and the liquid guide plate B (1200). S2, the directed wastewater flows obliquely toward the corresponding dispersion plate (802), and the corresponding dispersion plate (802) is pushed to rotate by the impact force of the water flow, and the rotating drum (801) rotates accordingly. The multiple dispersion plates (802) are impacted by the water flow in turn, so that the rotating drum (801) rotates continuously, and the liquid pump (600) transports the chemical treatment agent in the liquid tank (700) into the rotating drum (801). Due to the pressure, the chemical treatment agent enters the inner cavity of the dispersion plate (802) from the inner cavity of the rotating drum (801) through the connecting pipe A (804) and the connecting pipe B (805), and then is sprayed out from the holes on the dispersion plate (802). The sprayed chemical treatment agent is in a rotating spraying state due to the rotation of the dispersion plate (802), and cooperates with the dispersion plate (802) to disperse the wastewater, and the sprayed chemical treatment agent fully contacts and reacts with the wastewater; S3. Due to the centrifugal force of rotation and gravity, the connecting pipe A (804) and the connecting pipe B (805) are extended and contracted, and the dispersion plate (802) is in a movable state relative to the rotating drum (801), and the sprayed chemical treatment agent is further dispersed; S4, the wastewater then flows along the liquid guide plate C (1400) to the upper side of the filter screen (1300) and then falls down. The wastewater after the reaction with the chemical treatment agent passes through the filter screen (1300), and the filter screen (1300) separates the reactants in the wastewater. The reactants fall to the lower side of the filter screen (1300) through the inclined filter screen (1300); S5. In conjunction with the rotation of the drum (801), the rotating shaft (803) rotates relative to the channel A (100), and the sprocket A (1501) rotates accordingly. The sprocket A (1501) drives the sprocket B (1503) to rotate through the chain A (1502), causing a connecting rod (902) to rotate. In conjunction with the transmission of the sprocket C (904) and the chain B (905), multiple lifting buckets (903) continue to perform lifting movements. The lower lifting bucket (903) contacts the reactants at the lower part of the filter screen (1300) and scoops them up. After the lifting bucket (903) filled with reactants is lifted to the top, it is thrown into the slag discharge channel (400). In conjunction with the slag guide plate (401), the reactants are discharged from the slag discharge channel (400).
