Description
Technical Field
[0001] The invention relates to the technical field of sewage treatment, and in particular to a sewage treatment pool. Background Art
[0002] In daily life, people produce a large amount of domestic wastewater, which will first flow into the sewage treatment plant. The wastewater will undergo multiple filtration and purification in the sewage treatment pool. When the wastewater meets the discharge standards, the purified wastewater will be discharged into rivers and seawater through specific discharge pipes, thereby reducing the pollution of wastewater to the water environment and land; therefore, the sewage treatment pool is the key to wastewater treatment.
[0003] Existing sewage treatment pools are divided into multiple types of treatment pools according to general process flows, such as anoxic pools, aeration pools, and sedimentation pools. These treatment pools generally operate independently and are connected by pipes. Wastewater needs to be treated in each treatment pool in sequence according to the process flow steps. This assembly line treatment step greatly improves the efficiency of wastewater treatment. However, this will cause the sewage treatment pool to occupy a large amount of space and consume a large amount of energy. Therefore, a sewage treatment pool that can improve wastewater treatment efficiency, save space occupancy, and reduce energy consumption is needed to solve the shortcomings of the existing sewage treatment system.
[0004] For example, the patent with announcement number CN107381671B provides a sewage treatment pool, which includes a pool body, a heat collecting device and a heat dissipating device, and the heat collecting device and the heat dissipating device are used to effectively conduct heat to the bottom of the pool. This application can effectively conduct heat to the bottom of the pool, so that a flowing water flow is formed in the sewage water body to be treated; although this solution can achieve heat conduction and water flow, it cannot simultaneously achieve anaerobic treatment, aeration treatment and sedimentation treatment processes in the treatment pool; this solution cannot achieve multi-stage treatment of wastewater, let alone improve the treatment effect of wastewater; this solution cannot recycle and purify the waste gas and recyclable gas generated during the wastewater treatment process; when filtering particles in sewage in the prior art, the filter holes are often blocked by particles, thereby reducing the filtering effect and efficiency; this solution also does not have a corresponding mixing device, so it cannot achieve automatic mixing and spraying of the agent.

[0044] Working principle of the present invention: Figure 1 and Figure 2The usage and corresponding scenarios of the present invention are given. The posture control of the sewage treatment process is determined by the composite device 1, the mixing device 2, and the gas collecting device 3. The posture of the mixing device 2 is determined by the composite device 1, and the posture of the gas collecting device 3 is determined by the composite device 1. Therefore, the composite device 1 is the core of the sewage treatment process.
[0045] Taking the first embodiment as an example, the sewage is first poured into the central centrifugal cylinder 110, and the motor 102 on the composite device 1 drives the first gear 101 to rotate. The first gear 101 drives the spiral filter cylinder 109 to rotate through the second gear 104, and the spiral filter cylinder 109 drives the double-threaded lead screw 112 to move up and down. The double-threaded lead screw 112 drives the central centrifugal cylinder 110 to rotate in the opposite direction through the first ball 113, so that the sewage is thrown out from the central centrifugal cylinder 110 into the spiral filter cylinder 109. The sewage will first be thrown out into the second spiral chamber 117, at which time it will be mixed with the agent sprayed by the mixing device 2 to remove the heavy metals in the sewage. Then the sewage passes through the first filter hole 118 and enters the first spiral chamber 116. The activated sludge in the first spiral chamber 116 will preliminarily decompose the organic matter in the sewage and filter the tiny particles, thereby realizing the centrifugal decomposition and heavy metal removal functions of the sewage. Then the sewage flows from the first spiral chamber 116 to the bottom of the shielding component 114 , at this time, the aeration component 5 introduces oxygen into the sewage, thereby further oxidizing and decomposing organic matter in the sewage. The oxygen monitor 130 on the shielding component 114 will monitor the oxygen in the sewage, thereby controlling the oxygen output of the aeration component 5. When the oxygen is too high, the oxygen will drive the pressure ball 129 to move upward, and the pressure ball 129 drives the shielding cover 128 to rotate through the shielding screw 132, so that the shielding chassis 127 is opened. At the same time, the electric push rod 304 of the gas collecting device 3 drives the closing plate 305 to lift, so that the arc-shaped notch 123 of the centrifugal chassis 124 is opened, and excess oxygen and exhaust gas enter the gas collecting device 3. When the double-threaded screw 112 rises a certain distance, it will touch the first switch 306 on the gas collecting device 3, so that the motor 102 rotates in the opposite direction, and the motor 102 drives the spiral filter cartridge 109 to reverse. The spiral filter cartridge 109 shakes off the filtered sediment through the inertia during reversal, thereby achieving dredging of the first filter hole 118. The first water pump 105 pumps the water in the water storage tank 106 into the mixing cylinder 201 of the mixing device 2. At this time, the water flow will push the inclined plunger 208 in the mixing valve 202 upward, so that the upper end of the folding channel 209 is connected to the feed pipe 205. At the same time, according to the size of the water flow, the part of the folding channel 209 connected to the feed pipe 205 will also change accordingly, thereby changing the flow rate of the agent feed to achieve automatic mixing and flow control of the agent. The mixed agent will flow into the annular water storage tank 203, and then sprayed into the first spiral chamber 116 and the second spiral chamber 117 of the filter cartridge body 115 through the annular shower 204 to achieve the spraying function of the agent. The exhaust gas and oxygen are collected by the gas collecting cylinder 302 above the central centrifugal cylinder 110, and then the exhaust gas is purified by the purification device 4, and the purified oxygen is reused in the aeration component 5 to achieve the treatment of the exhaust gas and the recycling of oxygen.
[0046] Specifically, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, first pour the sewage into the central centrifugal cylinder 110, then the motor 102 on the pool body 103 drives the first gear 101 to rotate, the first gear 101 drives the spiral filter cartridge 109 to rotate through the second gear 104, the spiral filter cartridge 109 drives the double-threaded lead screw 112 to move up and down through the second ball 120 at the upper end of the first sleeve 121, and the double-threaded lead screw 112 drives the central centrifugal cylinder 110 to rotate in the opposite direction through the first ball 113 at the upper end of the second sleeve 126, so that the sewage is thrown out from the centrifugal cylinder body 122, and then flows into the filter cartridge body 115 through the second filter hole 119. The sewage is then mixed with the agent sprayed by the mixing device 2 to remove the heavy metal precipitation in the sewage. Then, the precipitate in the sewage is filtered through the first filter hole 118 and enters the first spiral chamber 116. The activated sludge in the first spiral chamber 116 will preliminarily decompose the organic matter in the sewage and absorb and filter the tiny particles, thereby realizing the centrifugal decomposition and heavy metal removal functions of the sewage. Then, the sewage flows from the bottom of the first spiral chamber 116 into the space under the shielding component 114. At this time, the aeration component 5 will pass oxygen into the sewage, thereby realizing the sewage.
