工业清洗产生的废水处理，长期是成本“黑洞”。传统蒸发结晶工艺需要100℃以上高品质蒸汽或电能，能耗高、设备贵。但有一项新技术，把这个门槛拉到了60-70℃——用钢铁厂、石化厂的低温余热，就能“煮”出高品质回用水。

The treatment of wastewater generated from industrial cleaning is a long-term cost "black hole". The traditional evaporative crystallization process requires high-quality steam or electricity at temperatures above 100 ℃, with high energy consumption and expensive equipment. But there is a new technology that has raised this threshold to 60-70 ℃ - using low-temperature waste heat from steel and petrochemical plants, high-quality recycled water can be "boiled".

核心技术：低温蒸滤+水平管降膜蒸发。

Core technology: Low temperature steam filtration+horizontal tube falling film evaporation.

以山东蓝想环境科技为例，其研发的“工业废水出色热法浓缩技术装备”，利用水平管降膜蒸发和蒸汽喷射器协同热力循环。低品位废热（如钢厂冲渣水、石化低温蒸汽）进入系统后，让废水在全封闭环境中完成“分家”：盐分被合理截留，废水变成高品质清水。

Taking Shandong Lanxiang Environmental Technology as an example, its developed "Industrial Wastewater High Efficiency Thermal Concentration Technology Equipment" utilizes horizontal tube falling film evaporation and steam jet synergistic thermal cycle. After low-grade waste heat (such as steel mill slag flushing water and low-temperature steam from petrochemicals) enters the system, the wastewater is separated in a fully enclosed environment: salt is accurately intercepted, and the wastewater becomes high-quality clean water.

效果有多惊人？

How amazing is the effect?

水资源回用率95%以上，产水品质直逼蒸馏水，可直接回用于生产。

The water resource reuse rate is over 95%, and the quality of the produced water is close to distilled water, which can be directly reused for production.

吨水处理成本控制在2元以下，仅为传统膜法工艺的三分之一。

The cost of treating one ton of water is controlled below 2 yuan, which is only one-third of the traditional membrane process.

实战数据：国内某大型石化基地，该系统年处理高盐废水146万吨，通过回收1.4万吨余热蒸汽，年减碳近5000吨，单是节约的水费和能耗成本，一年就超500万元。

Practical data: In a large petrochemical base in China, the system processes 1.46 million tons of high salt wastewater annually, recovers 14000 tons of waste heat steam, and reduces carbon emissions by nearly 5000 tons annually. The saved water and energy costs alone exceed 5 million yuan in one year.

政策背书：该技术已入选工信部、水利部联合发布的《国家鼓励的工业节水工艺、技术和装备目录（2025年版）》，并认定为2025年度山东省首台（套）技术装备。

Policy endorsement: This technology has been included in the "Catalogue of Industrial Water saving Processes, Technologies, and Equipment Encouraged by the State (2025 Edition)" jointly released by the Ministry of Industry and Information Technology and the Ministry of Water Resources, and has been recognized as the first (set) technological equipment in Shandong Province in 2025.

对于高耗水、高耗能的清洗行业来说，这不是“锦上添花”，而是“雪中送炭”。用原本白白排掉的废热，处理原本成本高昂的废水——一套设备，两头赚钱。

For the high water and energy consuming cleaning industry, this is not just adding icing on the cake, but providing timely assistance. Using the waste heat that was originally wasted to treat the expensive wastewater - one set of equipment, making money at both ends.
