1、 Policy driven transformation: Zero discharge of coal chemical wastewater is imperative;
In 2023, the National Development and Reform Commission issued the "Guiding Opinions on Water Conservation and Zero Wastewater Discharge in the Coal Chemical Industry", which clearly requires that all newly built/renovated coal chemical projects must achieve zero wastewater discharge before 2025, and existing projects must complete technological transformation. Under policy pressure, industry pain points are highlighted:;
-Complex water quality: containing toxic substances such as phenol, cyanide, tar, etc., making treatment difficult;
-High cost: Traditional water treatment processes cost over 50 yuan per ton, which imposes a heavy burden on enterprises;
-Technical barriers: Key technologies such as salt crystallization and membrane fouling control have not yet been fully localized.
Baihuipu Environmental Protection has developed a full chain technology solution of "pretreatment membrane concentration evaporation crystallization resource recovery" to address the aforementioned pain points, achieving a cost reduction of over 40% in wastewater treatment.
2、 Technological Breakthrough: The Four Innovative Engines of Baihuipu Environmental Protection;
1. Targeted preprocessing technology;
-Multiphase catalytic oxidation tower: using heterogeneous catalysts, the COD removal rate is increased to 85%, solving the problem of organic matter degradation;
-Intelligent flocculation system: By dynamically adjusting the dosage of chemicals through AI algorithms, the consumption of flocculants can be reduced by 30%.
2. Integrated process of high anti fouling film;
The acid and alkali resistant composite membrane developed by Baihuipu has a flux twice that of traditional membranes and a lifespan 50% longer. Combined with pulse backwashing technology, it effectively solves the problem of membrane fouling. After the application of a coal to gas project, the continuous operation cycle of the system has been extended from 7 days to 30 days.
3. Low carbon evaporation crystallization system;
-MVR+Multi effect Coupled Evaporator: Thermal efficiency increased by 60%, steam consumption reduced by 45%;
-Crystal type control salt separation technology: produces sodium sulfate and sodium chloride with a purity of ≥ 98.5%, meeting the industrial first-class standard, with an annual resource utilization income of over ten million yuan.
4. Digital twin operation and maintenance platform;
By using IoT sensors and 3D modeling, real-time simulation of device operation status and predictive maintenance can reduce the failure rate by 70%. After a coking park in Shanxi Province was connected to the system, the cost of manual inspection decreased by 60%.
III. Empirical Case: Win win of Economic and Environmental Benefits;
Case 1: Ningxia Coal based New Materials Project;
-Processing scale: 8000m ³/day;
-Core technology: Baihuipu's combination process of "electrocatalytic oxidation+TRO film+fractional crystallization";
-Result: The total COD removal rate is 99.2%, with an annual recovery of 32000 tons of industrial salt and a water-saving benefit of 20 million yuan per year;
Case 2: Xinjiang Coal to Oil Wastewater Project;
-Pain points: high oil content and complex salt content (TDS>150000 mg/L);
-Solution: Customized "Air Floatation Oil Removal Special Membrane Concentration Multi stage Crystallization" System;
-Effect: Oil removal rate of 99.8%, crystalline salt resource utilization rate of 95%, project awarded as "National Green Factory";
4、 Future prospects: Three major directions for the evolution of zero emission technologies;
1. Energy synergy: Combining evaporation systems with waste heat power generation and photovoltaic hydrogen production to create a "zero carbon water treatment" model;
2. Precise recycling: Developing materials such as molecular sieve adsorption and ion exchange resins to extract rare metals such as molybdenum and vanadium from wastewater;
3. AI deep empowerment: Utilizing machine learning to optimize parameters such as drug dosage and crystallization cycle, achieving completely unmanned operation.
Baihuipu Environmental Protection has partnered with Tsinghua University to establish the "Coal Chemical Water Resources Laboratory", which has obtained 17 patents in the fields of membrane material modification and crystallization kinetics, and continues to promote technological iteration.
Zero discharge of coal chemical wastewater is not only a requirement for environmental compliance, but also an opportunity for enterprises to transform from a "cost center" to a "resource center". Through technological innovation, Baihuipu Environmental Protection converts salt, organic matter, and heat in wastewater into tradable resources, helping customers increase their annual income by over 15%. With the implementation of policies such as the pilot expansion of water resource tax reform, zero emission technology will become the core competitiveness of coal chemical enterprises.
