Description

Sponge urban sewage purifying system

Technical Field

The invention relates to the technical field of sewage treatment and purification, in particular to a sponge urban sewage purification system.

Background

The sponge city is an innovative concept which is put forward in the field of urban water resource management and environmental protection in recent years, and aims to optimize the rainwater management, sewage treatment and water resource utilization of the city by simulating the natural water circulation process. The core idea of the concept is that the urban water treatment device can effectively absorb, store, permeate, purify and recycle rainwater like a sponge, thereby relieving urban water pollution.

The sewage purification technology is used as an important component of sponge city construction, and aims to improve the sewage treatment effect, reduce the treatment energy consumption and improve the water quality through a series of ecological purification methods. The flocculation technology is used as a mature water treatment process and is widely applied to sewage treatment, wastewater recycling and drinking water purification. The flocculation process mainly comprises the step of adding a flocculation agent into sewage to promote mutual adsorption and aggregation of fine particles and colloid substances in the water so as to form larger flocculation. The flocks can be removed from water by gravity sedimentation, filtration and other methods, and the water quality is obviously improved.

Currently, a method of adding a flocculating agent to the entire sewage tank or the sewage tank is to rapidly treat a large amount of sewage. The method has the main advantages of higher treatment efficiency, capability of treating a large amount of sewage at one time, simplicity, high automation degree in the operation process and suitability for a large-scale sewage treatment system.

In sponge cities, sewage treatment typically relies on a number of small, distributed treatment units, such as a rainwater garden, a percolating well, an artificial wetland, etc. These small systems have a low throughput and, in the case of low sewage volumes, conventional coagulant addition ratios are generally based on large-scale system designs which assume a large sewage treatment capacity and a high water flow rate. For small scale systems, the actual amount of flocculant required is much lower than the large scale calculated amount due to the small water volume. Thus, the conventional proportion calculation results in excessive addition of the flocculant, and the optimal treatment effect cannot be achieved.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1 to 9, a sponge municipal sewage purification system, comprising:

A purge bin 100;

The mixing chamber 101 is arranged in the purifying box body 100, the baffle plate 102 is arranged in the mixing chamber 101, the elastic piece 103 is arranged between the baffle plate 102 and the mixing chamber 101, the elastic piece 103 can be a spring, and the pressure chamber 104 is formed between the baffle plate 102 and the mixing chamber 101;

A top box 105 arranged at the top of the purifying box body 100, wherein a sewage cavity 106 and a plurality of medicament cavities 107 are formed in the top box 105;

A mixing section 108 provided in the mixing chamber 101 and rotatably provided in the mixing chamber 101;

A bottom tank 109 provided at the bottom of the purifying tank 100 for receiving sewage and liquid of the chemical;

A moving member provided between the mixing chamber 101 and the purge bin 100 for moving up and down the position of the mixing chamber 101;

The conveying component is arranged between the mixing cavity 101 and the top box 105 and is used for opening the mixing cavity 101 and the top box 105 when the mixing cavity 101 moves upwards to a preset position so as to quantitatively convey sewage into the mixing cavity 101;

An injection member disposed between the medicine chamber 107 and the mixing chamber 101 for quantitatively delivering the medium in the medicine chamber 107 into the mixing chamber 101 when the mixing chamber 101 moves down to a preset position;

wherein the mixing part 108 can rotate in the mixing cavity 101 when the mixing cavity 101 moves;

wherein, when the mixing cavity 101 moves downwards to a preset position, the bottom of the mixing cavity can be automatically opened to release the liquid into the bottom box 109;

By arranging the top box 105, the sewage source can be communicated with the top box 105 when in use, a part of sewage liquid is temporarily stored by the top box 105, and the sewage cavity 106 in the top box 105 can temporarily store sewage to be treated, so that the liquid flow in the whole sewage purification process is ensured. The medicament chamber 107 that sets up has a plurality ofly, and medicament chamber 107 can hold different grade type medicament, and is common like flocculating agent, flocculation auxiliary agent etc. according to actual demand, the design in medicament chamber 107 can allow throwing into one or more medicament chambers 107 with flocculating agent, also can select different medicaments in the flexible choice of different purification stages, and this makes the whole purification process can handle the kind and the concentration variation of pollutant in the sewage more accurately to effectively promote sewage treatment efficiency. In the actual purification process, the position of the mixing cavity 101 can be adjusted by utilizing the moving component, the mixing cavity 101 is gradually close to the top box 105 by moving the position of the mixing cavity 101 upwards, when the mixing cavity 101 moves upwards to a preset position, a communication channel between the mixing cavity 101 and the top box 105 is opened, the volume in the mixing cavity 101 is determined, when the mixing cavity 101 is opened, sewage freely flows in the mixing cavity 101, specifically, the volume of the mixing cavity 101 is determined in design, only proper conveying time is required to be controlled, the sewage amount poured into the mixing cavity 101 each time is kept unchanged, the sewage amount treated each time is ensured to be consistent with a preset standard, and the sewage amount entering the mixing cavity 101 each time is ensured to be consistent and not influenced by other factors. When the mixing chamber 101 is moved up to the limit position and stopped for a predetermined time, sewage is poured into the mixing chamber 101 during this process, and at this time, the moving member starts to move down the position of the mixing chamber 101, and when the mixing chamber 101 starts to move down, the top of the mixing chamber 101 is automatically closed, blocking the sewage and blocking further flow thereof. At this time, the top closing mechanism of the mixing chamber 101 ensures that the contaminated water does not leak or be disturbed by other liquids, ensuring the accuracy of the subsequent injection process of the medicament. When the mixing chamber 101 continues to move down to the preset position, the injection means is activated to accurately extract the medium in the medicament chamber 107 and to quantitatively deliver the required medium into the mixing chamber 101. The injection part can inject the medicament into the mixing cavity 101 at a preset speed and precision according to the set medicament adding amount, so as to ensure that the medicament and sewage are fully mixed and reacted in the mixing cavity 101, thereby effectively improving the sewage purifying effect. The quantitative delivery of the medicament ensures the accurate addition of the medicament, avoids the problem of excessive or insufficient medicament, improves the use efficiency of the medicament and reduces the resource waste. It is worth noting that two different liquids can be injected in one tank, and the design of the mixing chamber 101 must take into account the volume and space requirements of each liquid due to its incompressibility. The design purpose of baffle 102 is reasonable separation sewage and medicament's space, avoids both to take place unnecessary interference at the injection in-process, and baffle 102 is supported by elastic component 103, and the selection of elastic component 103 makes baffle 102 when bearing sewage, can effectively resist the gravity influence of sewage, prevents that baffle 102 from taking place displacement or deformation, ensures the stable storage of sewage. Meanwhile, the supporting force of the elastic member 103 is adjustable, so that the partition 102 can generate a corresponding movement reaction when the medicine is added, and when the injection member is operated to quantitatively deliver the medium (such as the flocculating agent) into the mixing chamber 101, the pressure in the mixing chamber 101 is increased due to the addition of the medicine. Due to incompressibility of the liquid, the newly increased pressure will force the partition plate 102 to displace downwards, thereby freeing up more space to accommodate the injected medicament, by this design, the mixing chamber 101 can effectively accommodate sewage and medicament, and remain stable throughout the injection process of both liquids, ensuring smooth progress of the whole sewage treatment process, avoiding the problem of unstable treatment effect or medicament waste caused by volume limitation or uneven distribution. At the same time, this pressure variation helps to ensure that the medicament is able to fully contact the sewage in the mixing chamber 101. As the diaphragm 102 is displaced downwardly, the space within the mixing chamber 101 increases, which not only helps to contain more medicament, but also accelerates the contact and mixing of medicament with the contaminated water by the action of pressure. Specifically, within the mixing chamber 101, the medicament reacts with suspended and colloidal contaminants in the wastewater to form flocs. In this process, the agent combines with the contaminant through surface adsorption and chemical reaction to form a larger floc. The pressure change is helpful to increase the collision probability between the medicament and the pollutant, and promote more pollutant to contact with the medicament, thereby improving flocculation effect. the pressure driving function accelerates the aggregation process of the particles in the sewage, so that the reaction speed is higher and the reaction effect is better. As the medium is injected, the pressure generated will also change continuously and the liquid flow conditions in the mixing chamber 101 will also change. The pressure may cause turbulence in the liquid which causes the agent to come into sufficient contact with and collide with suspended matter in the wastewater, contributing to the enhanced activity of the flocculant. The hydrodynamic effect caused by pressure can break the surface tension of liquid, avoid the agglomeration phenomenon of medicament particles, maintain the high efficiency of the medicament, further optimize the flocculation effect, and ensure that the medicament can be rapidly and uniformly distributed in sewage instead of being deposited or aggregated in a container by pressure change. Therefore, the waste of the medicament can be avoided, and the use efficiency of the medicament is improved. Because the medicament molecules can be uniformly distributed and contacted with more pollutants, the consumption of the medicament is optimized, the reaction efficiency is greatly improved, so that the use amount of the medicament is reduced, and resources are saved. In addition, in sponge cities, sewage treatment typically relies on a number of small, distributed treatment units, such as a rainwater garden, a percolating well, an artificial wetland, etc. These small systems have less throughput and widely varying wastewater compositions, and may contain different types of contaminants and have widely fluctuating concentrations. This requires flexibility and adaptability of the sewage treatment system to cope with different sources of sewage and its changing water quality. In this context, by providing a plurality of medicament chambers 107 and flexibly adjusting the medicament according to the sewage quality changes, an effective solution is provided. Where the water quality is relatively poor, one or more of the medicament chambers 107 may be filled with medicament to accommodate variations in different contaminant types and concentrations. For example, when the concentration of suspended matters in the sewage is high, the flocculating agent can be injected into the agent cavity 107 to remove the particles in the water through flocculation reaction, and when toxic and harmful matters in the water are toxic and harmful matters, a specific adsorbent or chemical reactant can be added to improve the water quality, so that the sewage treatment is more accurate due to the flexible agent allocation scheme, and the resource waste or poor treatment effect caused by excessive or insufficient agents is avoided. Moreover, the design of the medicament cavity 107 enables the medicament to be put in real time according to the actual condition of sewage, so that the treatment process has higher adaptability and efficiency. One or more medicament chambers 107 may be selectively left empty of medicament for use when the water quality is relatively good. At this time, when the injection member is operated, air in the medicine chamber 107 is injected into the mixing chamber 101, and air is injected into the mixing chamber 101 to introduce bubbles into the mixing chamber 101, thereby improving fluidity of liquid and helping sewage and medicine to be more sufficiently stirred and mixed in the mixing chamber 101. The generation of bubbles increases the turbulence of liquid flow, ensures that sewage and the medicament are uniformly distributed in the mixing process, and improves the mixing effect. In some wastewater treatments, especially where oxidative degradation of organic contaminants (e.g., ammonia nitrogen, chemical oxygen demand, etc.) is desired, air injection can provide oxygen support to promote the oxidation reaction. Oxygen in the air can react with pollutants to help remove organic matters in the water, and the system can flexibly adapt to water quality change by controlling the empty position and use of the medicament cavity 107, and can perform proper reaction under different sewage treatment demands without frequently adjusting the operation mode of the whole system. Further, when the moving part works to enable the mixing cavity 101 to continuously move downwards and close to the bottom box 109, the mixing part 108 arranged in the mixing cavity 101 can rotate along with the movement of the mixing cavity 101, and the rotation of the mixing part 108 can generate a more vigorous stirring effect to ensure that sewage and the medicament are fully contacted in the mixing cavity 101. The rotatory mixed portion 108 has avoided gathering uneven and sedimentation uneven problem with solid particles, colloid material and medicament evenly distributed in the sewage, has promoted flocculation effect, and rotatory mixed portion 108 can help pollutant and medicament fully to react before sedimentation, increases the area of contact of medicament, reinforcing flocculation reaction to improve the efficiency of follow-up sedimentation process. Especially for the suspended tiny particles in sewage, the rotary mixing can effectively avoid the secondary dispersion of the particles, enhance the stability of the flocculation and promote the pretreatment before sedimentation. In the process of moving down the mixing part 108, the sewage, the medicament and the liquid can stay in the mixing cavity 101 for a moving time, so that the contact time of the medicament and the sewage is increased, which is particularly important for the reaction rate of the medicament, especially for the medicament which needs a certain reaction time to exert an effect, such as a flocculating agent, a flocculating aid and the like. By prolonging the contact time, the utilization rate of the medicament can be improved, and more efficient sewage purification is ensured. When the mixing chamber 101 is driven by the moving member to descend to a preset position, the bottom of the mixing chamber can be automatically opened to release the liquid into the bottom box 109, thereby completing a cleaning cycle. The design realizes rapid discharge of sewage and medicament after mixing through the automatic opening bottom release mechanism, effectively avoids liquid to stay in the mixing cavity 101 for too long, thereby reducing the possibility of excessive reaction between the medicament and the sewage and ensuring the high efficiency and stability of the treatment process. Each time the liquid is released, the quality and effect of each batch of treatment liquid are ensured to be optimal in each purification cycle through accurate calculation and control. The released liquid can smoothly flow into the bottom box 109 for subsequent sedimentation, filtration or other purification steps to further purify the water. The automatic release mechanism not only improves the operation efficiency of the system, but also reduces the need of manual intervention, so that the whole sewage treatment process is simpler, more convenient and more reliable. Compared with the prior art, the application can more accurately control the adding amount of the medicament by optimizing the mixing process and the reaction time and ensure enough contact time between the medicament and pollutants in the sewage by mixing the sewage and the medicament in a certain box or a purifying tank, thereby enhancing the flocculation reaction effect and improving the overall treatment efficiency, and solving the problems that the adding proportion of the flocculating agent and other medicaments is not easy to control and the purifying effect is influenced by excessive or too little adding in the sewage treatment and purification in the prior art.
