一、矿井污水处理设备概述
　　采煤废水复杂多变，在同一矿井废水中，同时含有铁、锰等重金属，硫、氟、氯等非金属及**污染物和悬浮物，有的矿井废水呈弱酸性，即使是同一矿井，所采层不同，废水性质也不同，甚至是差别很大。这给煤矿废水治理技术的选用带来很大的困难。
　　煤矿污水水质与一般城市污水性质类似，但不同于城市污水(城市污水中常包括部分工业废水)。其特征可概括为：水质水量变化较大，污染物浓度偏低，污水可生化性好，处理难度小。
　　二、矿井污水处理设备处理工艺特点
　　1.煤矿矿井废水处理工程是根据矿井水水质特点确定工艺技术参数，采用一次提升到混凝沉淀装置，再自流进入后续各处理构筑物，出水水质稳定可靠，动力设备较少，能耗较低。
　　2.采用混凝沉淀装置与砂滤罐相结合的工艺技术，主要处理构筑物采用组合式钢结构，具有占地面积小、使用寿命长、工程投资省、工艺简单、操作管理方便、运行成本低等特点。砂滤罐设计采用重力式无阀滤池，反冲洗完全自动，操作管理方便。
　　3.该煤矿矿井废水处理系统实现了自动加药、自动反冲洗的全过程监控，包括电控系统、上位监控系统和仪表检测系统。仪表检测系统包括加药流量、处理流量 、水池液位和加药箱液位、进水和出水浊度等连续自动检测。
三、矿井污水处理设备处理工艺概述
　　煤矿污水处理在80年代采用活性污泥法处理工艺的较多，由于污水中**物含量太低，在运转过程中微生物得不到较低限度的营养物质，形不成活性污泥，运转不起来。氧化沟污水处理工艺，也存在同样的问题，回流活性污泥回流不起来，致使原氧化沟系统变成了附加曝气的带状平流沉淀池，达不到要求的处理目标。90年代许多矿井采用二级生物接触氧化法处理煤矿生活污水，效果很好。此工艺的特点是能适应矿区低浓度、变化大的污水，同时投资省，操作维护也比活性污泥法简单，但该法对脱氮除磷效果较差。90年代以来污水生物处理新工艺、新技术的研究开发应用取得了很大成就，许多新工艺应运而生，这些新工艺的共同特点是：高效、稳定、节能，并具有脱氮除磷等多功能。
　　四、济宁天通简述
　　目前部分煤矿工业场地和居住区各建一座污水处理厂，两处征地，重复建设，投资增加，运行能耗高，管理费用高，技术力量分散，吨水处理成本高。一般来说，矿井工业场地和居住区相距不是很远，合建一座一定规模的污水处理厂更合理，考虑从居住区向工业场地排水，管道埋设太深，可在中间设置污水提升泵站，或者在工业场地与居住区中间地段征地建设污水处理厂。采取合建方式，不但可节省投资，且可大大降低运行成本。

A summary of mine *age treatment equipment
Coal mining waste is complicated, at the same mine wastewater containing iron, manganese, and other heavy metals, sulfur, fluorine, chlorine and other non metals and organic pollutants and suspended solids, some mine wastewater is weak acidity, even the same mine, the different properties of wastewater are also different, even very different. This brings great difficulties to the selection of the technology for the treatment of coal mine wastewater.
The water quality of the coal mine is similar to that of the general urban *age, but it is different from the urban *age (urban *age often includes some industrial waste water). The characteristics can be summarized as follows: the water quality and water change is large, the concentration of pollutants is low, the *age can be biodegradable and the treatment is difficult.
Two. Characteristics of treatment process of mine *age treatment equipment
1., the coal mine wastewater treatment project is based on the characteristics of mine water quality, and determines the technological parameters. It is upgraded to coagulating sedimentation device at once, and then flows into the subsequent treatment structures. The effluent quality is stable and reliable, and the power plant is less, and the energy consumption is low.
2., the technology of combining coagulation sedimentation device and sand filter tank is adopted. The main structure is steel composite structure, which has the characteristics of small footprint, long service life, low investment in engineering, simple operation, convenient operation and management, low operation cost and so on. The design of sand filter adopts gravity type valveless filter, backwashing is completely automatic, and the operation and management is convenient.
3., the coal mine wastewater treatment system realizes the whole process monitoring of automatic dosing and automatic backwashing, including the electric control system, the upper monitoring system and the instrument detection system. The meter detection system comprises a dosing flow, processing flow, tank level and feeding box level, influent and effluent turbidity continuous automatic inspection.
Three. Summary of treatment process of mine *age treatment equipment
In 80s, the activated sludge process of coal mine *age treatment is more. Because of the low organic matter content in the *age, the microorganism can not get the lowest nutrient substance during operation, and it can't form activated sludge and can't run well. The oxidation ditch wastewater treatment process also has the same problem. The reflux activated sludge can not flow back, causing the original oxidation ditch system to become a strip aeration flat sedimentation tank, which can not reach the required treatment target. In 90s, many mines have adopted two stage biological contact oxidation process to treat coal mine domestic *age, and the effect is very good. The characteristics of this technology are that it can adapt to the low concentration and large change of *age in the mining area. At the same time, the investment and operation and maintenance are also simpler than the activated sludge process, but this method has a poor effect on nitrogen and phosphorus removal. Since 90s, great achievements have been made in the research, development and application of new technologies and technologies for wastewater biological treatment. Many new technologies come into being. The common characteristics of these new processes are: high efficiency, stability, energy saving and multi-function such as nitrogen and phosphorus removal.
Four, brief introduction to Jining Tian Tong
At present, a *age treatment plant is built in some coal industrial sites and residential areas. Two land acquisition, repeated construction, increased investment, high running energy consumption, high management cost, scattered technology force and high cost of water treatment. In general, mine industrial site and the residential area is not very far apart, to build a *age treatment plant of a certain size is more reasonable, considering from the residential area to the drainage industrial site, pipeline buried too deep, can be set in the middle of *age lifting pumping station, or in industrial sites and residential land to build a *age treatment plant in the middle area. Take the building, not only can save investment, and can greatly reduce the operation cost.
