Description

一种建筑工程废水一体化处理终端Integrated treatment terminal for construction engineering wastewater 技术领域Technical field
本发明涉及水处理环保领域，具体说是一种建筑工程废水一体化处理终端。The invention relates to the field of water treatment and environmental protection, in particular to an integrated treatment terminal for construction engineering wastewater.
背景技术Background technique
随着新型城镇化的建设，建筑行业产生了大量的污染物。特别是在地质冲孔施工过程中产生大量的含各类杂质的废水，在载体桩基施工过程中，由于降水也会产生大量的含铁、锰等杂质的地下水，此外还有混凝土浇灌、混凝土养护、车辆冲洗等产生的废水，这些混合有地质层杂质的废水较为零散，不便集中处理，基本上是直接排放。With the construction of new urbanization, the construction industry has produced a lot of pollutants. Especially in the process of geological punching construction, a large amount of wastewater containing various impurities is generated. During the construction of carrier pile foundation, due to precipitation, a large amount of groundwater containing impurities such as iron and manganese will also be generated. In addition, there are concrete pouring and concrete. Wastewater generated from maintenance, vehicle washing, etc., these waste water mixed with geological layer impurities are relatively scattered, inconvenient for centralized treatment, and are basically directly discharged.
近几年绿色建筑理念的提出，一些建筑公司和科研机构在此方面也正在进行探索和研究，废水污染问题得到了一定的改善。现有技术多采用带溢流堰的沉降池进行澄清后排放，这样的操作模式多为单元沉降，需要建多个大容量的沉降池用于废水处理，而且施工完成后需要将沉降池拆除，耗资巨大，处理效果差，废水沉降时间过长，无法循环利用，不但达不到了环保排放的要求，而且水资源利用率低。也有一些专利技术提供了有益的处理方法，采用多级、多组反复过滤和加药处理工艺，但投资高、结构复杂、处理工艺过剩、占地面积大、稳定连续运行周期短、运行成本高、经济性差，需要人工现场维护，难以进一步推广和应用。In recent years, the concept of green building has been put forward, and some construction companies and scientific research institutions are also exploring and researching in this regard, and the problem of wastewater pollution has been improved to a certain extent. In the prior art, sedimentation tanks with overflow weirs are mostly used for clarification and discharge. This mode of operation is mostly unit sedimentation. It is necessary to build multiple large-capacity sedimentation tanks for wastewater treatment, and the sedimentation tanks need to be dismantled after the construction is completed. The cost is huge, the treatment effect is poor, and the wastewater sedimentation time is too long to be recycled. Not only does it fail to meet the requirements of environmental protection discharge, but also the utilization rate of water resources is low. There are also some patented technologies that provide beneficial treatment methods, using multi-stage, multi-group repeated filtration and dosing treatment processes, but the investment is high, the structure is complicated, the treatment process is excessive, the area is large, the stable continuous operation period is short, and the operating cost is high. , Economic efficiency is poor, manual on-site maintenance is required, and it is difficult to further promote and apply.
如何解决建筑工程此类废水的污染，急需一种经济实用、稳定可靠、社会效益好、水资源利用率高的废水处理装置。How to solve this kind of waste water pollution in construction projects requires an economical, practical, stable and reliable waste water treatment device with good social benefits and high water resource utilization rate.
