[0053] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0054] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0055] like Figure 1 , Figure 2FIG. 1 is a schematic diagram of a novel high-concentration waste liquid treatment system provided by an embodiment of the present invention. The system includes a pretreatment device 100 and a precipitation purification device 200. The pretreatment device 100 includes:

[0056] An integrated housing 1, wherein the integrated housing 1 is provided with a sedimentation chamber 2, a pretreatment mixing chamber 3, a collection chamber 4, a diversion chamber 5 and a treatment agent storage chamber 6;

[0057] The sedimentation chamber 2 is arranged at the bottom;

[0058] The pretreatment mixing chamber 3 is arranged on one side above the sedimentation chamber 2;

[0059] The collecting chamber 4 is arranged on the other side above the sedimentation chamber 2;

[0061] The treatment agent storage chamber 6 is arranged above the pretreatment mixing chamber 3;

[0062] The top of the diversion chamber 5 is connected with a water inlet pipe 7;

[0063] The pretreatment mixing chamber 3 is connected to an overflow pipe 8;

[0064] An arc-shaped filter element 9 is provided at the connection point between the diversion chamber 5 and the pretreatment mixing chamber 3;

[0065] The diversion chamber 5 is provided with a diversion mechanism 300;

[0066] A pretreatment purification mechanism 400 is disposed in the pretreatment mixing chamber 3 .

[0067] In the embodiment of the present invention, when in use, high-concentration waste liquid is introduced into the water inlet pipe 7, and the waste liquid enters the diversion chamber 5. The waste liquid is diverted one by one through the diversion mechanism 300 to divide the waste liquid into equal units. On the one hand, the waste liquid of one unit is filtered through the arc filter element 9 under the action of gravity and falls into the pretreatment mixing chamber 3. The treatment agent in the treatment agent storage chamber 6 is automatically introduced into the pretreatment mixing chamber 3 through the pretreatment purification mechanism 400 to mix with the waste liquid of one unit, and then introduced into the sedimentation chamber 2 for pretreatment precipitation. The waste liquid after precipitation enters the pretreatment purification mechanism 400 through the overflow pipe 8, which is convenient for subsequent multi-stage treatment, and can reduce the complex high-concentration waste liquid and process it successively in proportion. On the other hand, the impurities filtered on the arc filter element 9 are cleaned into the collection chamber 4 for treatment through the diversion mechanism 300. Compared with traditional equipment, the difficulty of subsequent sedimentation treatment can be reduced, and the gravity, the natural force, can be used to automatically distribute the proportion, which is energy-saving and environmentally friendly.

[0068] like Figure 2As shown, as a preferred embodiment of the present invention, the diversion mechanism 300 includes:

[0069] A rotating shaft 10, wherein the rotating shaft 10 is rotatably disposed on the axis of the diversion chamber 5;

[0070] A partition plate 11, wherein the partition plate 11 is evenly fixed on the rotating shaft 10 and slides closely with the inner wall of the rotating shaft 10;

[0071] The water inlet pipe 7 is located on a side of the rotating shaft 10 close to the arc-shaped filter element 9 .

[0072] In the embodiment of the present invention, when in use, under the action of gravity or the kinetic energy of the waste liquid, the partition plate 11 is impacted, so that the partition plate 11 is Figure 2 The waste liquid is separated one by one by two adjacent partition plates 11 when it rotates clockwise. Due to the inconvenience of the diameter of the water inlet pipe 7, that is, the inconvenience of the flow rate, the gravitational potential energy or kinetic energy of the fall, that is, the force acting on the partition plate 11 remains unchanged, the rotation change of the rotating shaft 10 is regular, so that equal amount of waste liquid can be diverted. The waste liquid is filtered through the arc filter element 9 and enters the pretreatment mixing chamber 3. The impurities falling on the arc filter element 9 are swept into the collection chamber 4 by the partition plate 11.

[0073] In one case of the present embodiment, a collection box 12 is nested on the side of the collection chamber 4, and the collection box 12 is provided with an open groove matching the diversion chamber 5. A handle is installed on one side of the collection box 12 outside the integrated shell 1, and the collection box 12 can be easily taken out by grabbing the handle, so as to process the impurities of the mobile phone in the collection box 12.

[0074] like Figure 2 As shown, as another preferred embodiment of the present invention, the pre-treatment purification mechanism 400 includes:

[0075] A guide plate 13, wherein the guide plate 13 is slidably disposed in the pretreatment mixing chamber 3 and is located below the arc-shaped filter element 9;

[0076] A stirring assembly 14, wherein the stirring assembly 14 is installed at the bottom of the guide plate 13;

[0077] An elastic support assembly 15, wherein the elastic support assembly 15 is used to support the guide plate 13;

[0078] A knocking rod 16, wherein the knocking rod 16 is installed at a position opposite to the guide plate 13 and the arc-shaped filter element 9;

[0079] The conduction control component 17 is fixed to the guide plate 13 and is used to control the conduction state between the treatment agent storage chamber 6 and the pretreatment mixing chamber 3 .

[0080] In the embodiment of the present invention, when in use, the gravitational potential energy of the filtered waste liquid impacts the guide plate 13 to move downward, and the guide plate 13 causes the elastic support component 15 to contract. Then, under the guidance of the guide plate 13, the wastewater falls to the bottom of the pretreatment mixing chamber 3. At this time, the guide plate 13 drives the conduction control component 17 to move, so that the treatment agent in the treatment agent storage chamber 6 falls into the pretreatment mixing chamber 3 and mixes with the waste liquid. Then, under the elastic force of the elastic support component 15, the guide plate 13 is driven to suddenly reset upward, and the guide plate 13 drives the knocking rod 16 to knock on the arc-shaped filter element 9, and then resets.

[0081] like Figure 3 As shown, as another preferred embodiment of the present invention, the elastic support component 15 includes:

[0082] A fixing plate 18, wherein the fixing plate 18 is fixed on the inner wall of the pretreatment mixing chamber 3;

[0084] The elastic member 20 is sleeved on the guide slide bar 19 and is located between the fixing plate 18 and the guide plate 13 .

[0085] In an embodiment of the present invention, when in use, the guide plate 13 drives the guide slide rod 19 to move downward, and the guide slide rod 19 cooperates with the fixed plate 18 to squeeze the elastic member 20 until the elastic member 20 can no longer shrink. At this time, the elastic force of the elastic member 20 suddenly drives the guide plate 13 to move upward, and the guide plate 13 drives the knocking rod 16 to knock on the arc-shaped filter element 9.

[0086] like Figure 2 , Figure 3 As shown, in one case of the present embodiment, a second V-shaped nested piece 28 is provided on one side of the pretreatment mixing chamber 3 close to the sedimentation chamber 2, and the elastic support assembly 15 also includes a pull rope 21, and the two ends of the pull rope 21 are respectively fixedly connected to the guide slide bar 19 and the second V-shaped nested piece 28. When the guide slide bar 19 is suddenly reset, the pull rope 21 is driven to move by the guide slide bar 19, and the pull rope 21 drives the second V-shaped nested piece 28 to move. There is a gap between the second V-shaped nested piece 28 and the integrated shell 1, and the mixed waste liquid flows into the sedimentation chamber 2 for pretreatment sedimentation, and then enters the pretreatment purification mechanism 400 for treatment through the overflow pipe 8.

[0087] like Figure 4 As shown, as another preferred embodiment of the present invention, the stirring assembly 14 includes:

[0088] A rotating sleeve 22, wherein the rotating sleeve 22 is rotatably disposed at the bottom of the guide plate 13;

[0089] An internal thread groove 23, wherein the internal thread groove 23 is disposed in the rotating sleeve 22;

[0090] A fixed screw 24, wherein the fixed screw 24 is fixed to the bottom of the pretreatment mixing chamber 3, and the fixed screw 24 is threadedly matched with the internal thread groove 23;

[0091] The stirring rod 25 is evenly fixed on the rotating sleeve 22 .

[0092] In the embodiment of the present invention, when in use, the guide plate 13 drives the rotating sleeve 22 to move, and the rotating sleeve 22 moves along the fixed screw 24, and cooperates with the fixed screw 24 through the internal thread groove 23, so that the rotating sleeve 22 rotates, and the rotating sleeve 22 drives the stirring rod 25 to rotate, thereby stirring and mixing the waste liquid and the treatment agent, thereby increasing the mixing speed.

[0093] like Figure 5 As shown, as another preferred embodiment of the present invention, the conduction control component 17 includes:

[0094] A fixing rod 26, the fixing rod 26 is fixed to the top of the guide plate 13, and the fixing rod 26 extends into the treatment agent storage chamber 6;

[0095] A first V-shaped nesting member 27, wherein the first V-shaped nesting member 27 is fixed in the fixing rod 26 and nested in the treatment agent storage chamber 6 from the pretreatment mixing chamber 3;

[0096] The narrower end of the fixing rod 26 is located at a side close to the treatment agent storage chamber 6 .

[0097] In the embodiment of the present invention, when the guide plate 13 moves, the guide plate 13 drives the fixing rod 26 to move, and the fixing rod 26 drives the first V-shaped nesting member 27 away from the treatment agent storage chamber 6. At this time, the purification agent in the treatment agent storage chamber 6 flows into the pretreatment mixing chamber 3 from the gap.

[0098] As another preferred embodiment of the present invention, the precipitation purification equipment 200 includes an evaporation concentration unit, a flocculation precipitation unit, a chemical precipitation unit, a biological adsorption unit, a filtration unit and a water storage unit.

[0099] In this embodiment, the pretreated waste liquid enters the evaporation concentration unit through the overflow pipe 8 for evaporation concentration, the concentrated concentrated liquid is sent to the flocculation sedimentation unit, and the concentrated solid sludge is collected and processed through the sludge discharge pipe; the pH in the flocculation sedimentation unit is adjusted, a coagulant is added, and the mixture is stirred evenly and then allowed to settle. The upper layer of liquid is sent to the chemical precipitation unit, and sulfide is added for sulfide precipitation; the reaction liquid after sulfide precipitation is sent to the biological adsorption unit, and after adsorption and reaction by the microorganism-active agent, the liquid is sent to the filtration unit for multiple filtrations, and the final dischargeable treated liquid is sent to the water storage unit for storage and use.

[0100] In one aspect of this embodiment, a plurality of microorganism-active agent adsorption layers are provided in the biosorption unit;

[0101] The microorganism-active agent adsorption layer is composed of an active agent and a microbial agent loaded on the active agent;

[0102] The active agent includes one or more of activated carbon, diatomaceous earth, zeolite and chitosan;

[0103] The microbial agent is Bacillus subtilis or yeast;

[0104] The preparation method of the microorganism-active agent is as follows: the active agent is calcined and then crushed, then placed in a bacterial basic culture medium, sterilized at high temperature, taken out and cooled to room temperature, then the microbial agent is added, and after soaking and culturing, it is rinsed with sterile water to obtain the microorganism-active agent;

[0105] The calcination temperature is 350-500°C and the calcination time is 20-60min;

[0106] The temperature of the high temperature sterilization is 110-125°C, and the sterilization time is 10-30min;

[0107] The soaking ratio of the above-mentioned active agent to the microbial agent is 1g: (50-100)mL. The specific process of the soaking culture is: mixing the active agent with the microbial agent, shaking and culturing at a temperature of 25-30°C and 100-150rpm for 24-48h; the evaporation concentration unit adopts a compression evaporator with an evaporation temperature of 100-105°C and an evaporation pressure of 0.5MPa, which is used to precipitate some ions with low solubility in the wastewater. A mud discharge pipe is provided at the bottom of the compression evaporator to discharge the solid impurities after concentration and precipitation out of the system.

[0108] Specifically, the flocculation sedimentation unit adds coagulants to the wastewater to generate flocs under the interaction of the macromolecular forces of the suspended colloids and dispersed particles in the wastewater. During the sedimentation process, the flocs collide and coagulate with each other, and their size and mass continue to increase, and they are eventually filtered out of the wastewater system; the chemical precipitation unit uses a precipitant to produce a chemical reaction with heavy metal ions to generate precipitates, thereby achieving the effect of removing heavy metal ions.

[0109] The present application adopts sulfide (specifically sodium sulfide and sodium hydrosulfide). Since the solubility product of sulfide is smaller than that of the hydroxide corresponding to the metal ion, it can break the complex formed by the reaction of heavy metal ions with hydroxide, thereby improving the precipitation effect of heavy metal ions. In addition, sulfide is used to treat the electroplating wastewater after the flocculation precipitation unit. The liquid after flocculation precipitation is alkaline, so the chemical precipitation step does not need to adjust the pH of the wastewater, reducing the use of additives and labor costs.

[0110] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
