As shown in fig. 1-3, the portable garbage transfer station sewage treatment and recycling system adopts the processes of dosing, physicochemical separation and oxidation decoloration for the purpose of meeting the actual water consumption condition of the garbage transfer station, and each link is described as follows:
1. waste water regulating tank
The water quantity and water quality of all sewage entering the sewage treatment system can change at any time, which is very unfavorable for the normal operation of a sewage treatment structure. The larger the fluctuation of water quantity and water quality, the more unstable the treatment effect is, and even the sewage treatment process is seriously damaged. In order to reduce the influence of water quantity and water quality change on the sewage treatment process, a regulating tank is arranged in front of a sewage treatment system to equalize water quality and make up for defects, so that subsequent treatment structures can obtain balanced water inflow and stable water quality during the operation period, and an ideal treatment effect is achieved.
2. Neutralization, coagulation and stirring integrated device
The process includes three steps of acid-base neutralization, coagulation (flocculation) and slow stirring and mixing.
When a neutralizing agent or coagulant (electrolyte) is added to the wastewater to increase the ion concentration in the solution, the thickness of the diffusion layer decreases. When two colloidal particles approach each other, the zeta potential decreases due to the decrease in the thickness of the diffusion layer, so that their mutual repulsive force decreases and the colloidal particles are rapidly aggregated. Through the action of adsorption and electric neutralization, colloidal particles are easy to approach other particles and mutually adsorb, and are condensed into large floccules. The aim of pretreatment can be achieved after the flocculating constituent is formed, and in order to prevent the flocculating constituent from quickly precipitating, a slow mixer is adopted for mixing and stirring, so that the flocculating constituent is kept in a suspension state.
3. Mud-water separation device
Because the wastewater has obvious periodic discharge characteristic, the sludge-water separation can meet the filtering effect by adopting a plate-and-frame filter press which operates intermittently. The filtered clear liquid enters a subsequent environment after being lifted, and the dried sludge and other garbage are compressed and reduced together and then are transported.
4. Multiphase air flotation device
The air-float water-purifying method is characterized by that it adopts multiphase flow pump to directly make air-dissolving and pressure-reducing release so as to make the water-dissolved large quantity of gas be used as working liquid, and when the pressure is suddenly reduced, the countless fine bubbles are released and adhered together with the impurities in the water undergone the process of mixing reaction, and the specific gravity of its flocculated body is less than 1, i.e. its density is less than 1g/cm3So as to float on the liquid surface to form a three-phase mixture of foam (namely air, water and particles), thereby separating pollutants from the wastewater and achieving the purpose of purification.
The waste water added with coagulant and coagulant aid and the gas-dissolving water react and coagulate in the reaction area of the air floating tank, and the coagulation of the original colloid into flocs is the working process of the machine. The whole reaction principle is that medicament diffusion, coagulation hydrolysis, impurity colloid destabilization colloid aggregation and micro-floc aggregation are carried out, so that the particle size of colloid particles is condensed into 2 mm flocs from 0.001 micron, the flocs quickly float upwards, the discharged water is scraped at regular time by a slag scraper, and the discharged water after reaction flotation automatically flows out from a water collecting tank.
Brief introduction of the structure:
the pressure dissolved air floatation process mainly comprises four parts, namely a pressure dissolved air system, a dissolved air release system, an air floatation separation system and an electric control system.
1) Pressure air dissolving system
Comprises a multiphase flow dissolved air water pump, a small air water buffer tank, a pressure detecting instrument and other accessory equipment.
2) Dissolved air release system
Is composed of pressure regulating valve and dissolved-air water pipeline.
In order to reduce corrosion, the pressure regulating valve and the gas dissolving water pipeline are made of stainless steel.
3) Air floatation separation system
The air floatation separation system adopts a horizontal flow type. The function is to ensure a certain volume and surface area of the pool, so that the micro-bubble groups are fully mixed, contacted and adhered with the flocculating constituents in water, and the flocculating constituents with gas are separated from clear water.
After the sewage is reacted in the coagulation reaction tank, the water flow is guided to the bottom so as to enter the air floatation contact chamber from the lower part, the contact time of flocs and bubbles is prolonged, scum on the tank surface is scraped into a scum collecting tank, and clear water is collected by a water collecting pipe at the bottom. The advantages of this form are shallow pool body, low cost, simple structure and convenient management.
5. Medicine adding device
The dosing equipment can be used for dosing acid, alkali, flocculating agent (PAC), coagulant aid (PAM) and other medicaments in the sewage treatment system. The dosing device has the characteristics of compact structure, complete preparation, rapid installation, simple operation and convenient maintenance.
The device can be used for preparing solution and quantitatively and regularly adding medicament. It is composed of the following parts: (1) a stirrer and a stirring drum; (2) adding a liquid medicine metering pump; (3) y-type filter, safety valve, pipeline system;
the working principle of the device is as follows: certain medicament is put into the stirring solution box according to the requirement for stirring, after the dissolution is finished, the control system controls the metering pump to deliver the medicament to the working process of a medicament adding point, and the size of the medicament adding amount can be freely adjusted to meet the requirements of different medicament adding places.
6. Ozone oxidation
The ozone has strong oxidizing power, the oxidation-reduction potential of the ozone is second to that of fluorine, the ozone can be used for quickly oxidizing and decomposing organic matters in wastewater in application, the COD and the chroma are reduced, and the ozone enters an adding pipeline after a manual valve, flow, pressure and temperature are displayed on site, flow monitoring and pressure monitoring. The feeding pipeline is provided with a pressure on-site display and a check valve, ozone gas is mixed with water in a micropore aeration mode, and residual ozone tail gas is discharged into the atmosphere after passing through the tail gas destruction device.
The ozone generator used by the company is a high-frequency ozone generator controlled by a microcomputer. Because a series of new products and new technologies such as a variable frequency variable voltage (VVVF) power circuit, Pulse Width Modulation (PWM) control, DSP digital processing control and the like which are formed by the current latest power electronic module are adopted, and the products are assisted by elaborate design, strict management and careful process control, the products have the advantages of simple operation, flexible control, compact structure, small volume, light weight and the like. Meanwhile, the soft start and soft unloading functions are designed, and the adding power of the ozone generator can be smoothly adjusted to reach the rated ozone output from 10 percent, so that the operation cost is reduced to the maximum extent.
7. Filtering and recycling
The water after oxidation and decoloration is filtered by a cloth bag filter and then is reused for ground cleaning of a transfer station, tire cleaning of a transport vehicle and dust suppression by road spraying.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
