技术领域technical field
本实用新型属污水处理装置，尤其是指一种矿井污水深度处理回用装置。The utility model belongs to a sewage treatment device, in particular to a mine sewage advanced treatment and reuse device.
背景技术Background technique
矿井污水处理一般分两部分，即预处理部分和深度处理部分，预处理部分通过絮凝、沉淀、过滤等常规工艺，达到生活杂用水标准，为了进一步达到城市供水水质标准，需进行深度处理，当前，深度处理是将前级处理后的水提升至多介质过滤器中，经石英砂过滤、活性炭过滤，然后超滤，再用精密过滤器去除微小颗粒，用泵加压进入膜渗透装置处理。该工艺中因先采用石英砂过滤，处理效果受到限制，为了满足膜处理的进水要求，活性炭过滤后还配备超滤装置，为了保护后序不断水能连接操作，另需为超滤单独配设水箱，一方面大大增加了固定资产投资，另一方面，因超滤装置反洗频繁，用水量很多，工艺运行成本大；其次，工艺中膜渗透装置中二段膜均采用单一膜，同一种膜会使产水量低，系统运行压力升高，整个膜渗透装置寿命短。Mine sewage treatment is generally divided into two parts, namely the pretreatment part and the advanced treatment part. The pretreatment part reaches the domestic miscellaneous water standard through conventional processes such as flocculation, sedimentation, and filtration. In order to further meet the urban water supply quality standard, advanced treatment is required. Currently , advanced treatment is to lift the pre-treated water into a multi-media filter, filter through quartz sand, activated carbon, and then ultra-filter, then use a precision filter to remove tiny particles, and use a pump to pressurize into a membrane permeation device for treatment. In this process, the treatment effect is limited due to the use of quartz sand filtration first. In order to meet the water inflow requirements of membrane treatment, an ultrafiltration device is also equipped after activated carbon filtration. In order to protect the subsequent continuous water connection operation, a separate configuration for ultrafiltration Installing a water tank, on the one hand, greatly increases the investment in fixed assets; on the other hand, due to the frequent backwashing of the ultrafiltration device, the water consumption is large, and the operating cost of the process is high; The kind of membrane will make the water production rate low, the operating pressure of the system will increase, and the life of the whole membrane permeation device will be short.
发明内容Contents of the invention
本实用新型正是为了克服上述不足，提供一种投资成本低、处理效率高、运行费用少的矿井污水深度处理回用装置，主要创新在于过滤先选用瓷砂过滤，因瓷砂微孔发达，孔隙率大，具有优良的吸附能力，其过滤处理效果好，后序工艺中不需另配超滤装置，就可满足膜渗透处理装置的进水要求，大大降低了投资成本，另外，在膜渗透装置中，采用组合式装配膜元件，即二段分别采用不同的膜，提高产水量，减少运行成本。具体是这样来实施的：矿井污水深度处理回用装置，包括管道连接的过滤装置、膜渗透装置，过滤装置前置有前级处理水的提升泵，膜渗透装置前置有高压泵，膜渗透装置后连接出水清水箱，其特征在于过滤装置依次由瓷过滤器、活性炭过滤器、精密过滤器顺序管道连接。瓷过滤器中的瓷砂是均匀的球形颗粒，球形之间是多点接触，孔隙均匀，中间形成许多弯弯曲曲的通道，水流经过滤层时流通距离长，为杂质造成一个非常理想的沉积条件。瓷砂表面有许多微孔，使悬浮物很容易被瓷砂表面吸附截留，并形成再生膜，超到过滤作用，截污能力大，瓷砂比表面积大约为8.5cm2/cm3，其最大饱和泥渣量为30.5kg/m3，是一般石英砂所不能比拟的。又由于瓷砂为球形，水流阻力小，自身比重轻，在进行反冲洗时，可借自身的滚动和相互摩擦，使附在球面上的泥渣很容易被清洗脱除，反洗时间短，水耗小，效果好，反洗时滤料的膨胀率仅10％，远小于石英砂滤料膨胀率40-50％，反洗强度为4.5-6L/S.m2，也远小于石英砂反洗强度12-15L/S.m2。The utility model is just to overcome the above-mentioned deficiencies, and provides a mine sewage advanced treatment and recycling device with low investment cost, high treatment efficiency and low operating cost. It has large porosity, excellent adsorption capacity, and good filtration treatment effect. In the subsequent process, no additional ultrafiltration device is needed, which can meet the water inlet requirements of the membrane permeation treatment device, which greatly reduces the investment cost. In addition, in the membrane In the osmosis device, a combined assembly membrane element is used, that is, different membranes are used in the second stage to increase water production and reduce operating costs. Specifically, it is implemented as follows: advanced mine sewage treatment and recycling device, including a filter device connected to a pipeline and a membrane permeation device. After the device is connected to the clean water tank, it is characterized in that the filter device is sequentially connected by a porcelain filter, an activated carbon filter, and a precision filter. The porcelain sand in the porcelain filter is a uniform spherical particle, with multi-point contact between the spheres, the pores are uniform, and many tortuous channels are formed in the middle. When the water flows through the filter layer, the flow distance is long, which creates a very ideal deposition for impurities. condition. There are many micropores on the surface of porcelain sand, so that the suspended matter is easily absorbed and intercepted by the surface of porcelain sand, and a regenerative film is formed, which has super filtration effect and great pollution interception capacity. The specific surface area of porcelain sand is about 8.5cm 2 /cm 3 , the largest The amount of saturated sludge is 30.5kg/m 3 , which is unmatched by ordinary quartz sand. And because the porcelain sand is spherical, the water flow resistance is small, and its own specific gravity is light. When backwashing, the mud attached to the spherical surface can be easily cleaned and removed by its own rolling and mutual friction, and the backwashing time is short. Small water consumption, good effect, the expansion rate of the filter material during backwashing is only 10%, which is much lower than the expansion rate of quartz sand filter material 40-50%, and the backwashing strength is 4.5-6L/Sm 2 , which is also much lower than that of quartz sand backwashing Strength 12-15L/Sm 2 .
瓷砂过滤器的出水浊度＜0.5NTU，SDI＜3，能满足后级膜渗透装置进水要求。瓷砂过滤器内的瓷砂在运行时不会破损，运行周期长，可长达10年左右不要更换，一般石英砂每年要更换一次或增添一部分，工艺过程中配置了瓷砂过滤器可节省一道超滤装置，可节约投资30-50％，耗水、耗电也大为节省。The effluent turbidity of the porcelain sand filter is less than 0.5NTU, and the SDI is less than 3, which can meet the water inlet requirements of the subsequent membrane permeation device. The porcelain sand in the porcelain sand filter will not be damaged during operation, and the operation cycle is long, which can last for about 10 years without replacement. Generally, the quartz sand needs to be replaced once a year or a part is added. The porcelain sand filter is configured in the process to save An ultrafiltration device can save investment by 30-50%, and greatly save water and electricity consumption.
本实用新型的膜渗透装置是采用组合式装配膜元件，即第一段和第二段采用不同的膜元件，如第一段采用超低压大流量相对脱盐率高的膜，第二段采用相对脱盐率较低的膜，反之也可。这种组合式装配膜元件的膜渗透装置，可减少系统中膜元件用量15％左右，减少投资，且产水量高，系统运行压力较低，膜渗透装置的使用寿命也长，经过膜渗透装置后的出水，水质主要指标均满足且优于城市供水水质标准。The membrane permeation device of the present utility model adopts a combined assembly membrane element, that is, the first section and the second section use different membrane elements, such as the first section adopts a membrane with ultra-low pressure and large flow rate and relatively high desalination rate, and the second section adopts a relatively high desalination membrane. Membranes with lower salt rejection, and vice versa. This combined membrane permeation device assembled with membrane elements can reduce the amount of membrane elements in the system by about 15%, reduce investment, and has high water production, low system operating pressure, and long service life of the membrane permeation device. The main water quality indicators of the final effluent all meet and exceed the urban water supply water quality standards.
本实用新型在瓷过滤器、活性炭过滤器的反洗水箱及反洗泵和膜渗透装置的清洗装置出水口间置有水循环连接管道，膜渗透装置的清洗装置的出水通过管道可作为瓷过滤器的反冲洗水，使整个工艺更紧凑，成本最低化。The utility model is provided with a water circulation connection pipe between the backwash water tank of the porcelain filter and the activated carbon filter, the backwash pump and the outlet of the cleaning device of the membrane permeation device, and the outlet water of the cleaning device of the membrane permeation device can be used as a porcelain filter through the pipeline. The backwashing water makes the whole process more compact and the cost is minimized.
本实用新型正是采用瓷过滤器替代石英砂过滤器，使矿井污水深度处理中大大节省了投资成本，膜渗透装置中用组合式膜元件，不仅使产水量高，运行成本低，且出水水质优于城市供水水质标准。The utility model just uses the porcelain filter to replace the quartz sand filter, which greatly saves the investment cost in the advanced treatment of mine sewage. The combined membrane element is used in the membrane permeation device, which not only makes the water production rate high, the operation cost is low, and the water quality of the effluent is high. It is superior to the urban water supply water quality standard.
