Recently, the environmental impact assessment for Hubei Yihua Group Co., Ltd.’s 1 million tons per year ferrophosphate production project was made public for the first time on relevant websites. Project Name: 1 million tons/year ferrophosphate project
Construction Unit: Hubei Yihua Group Co., Ltd.
Nature of Construction: New construction
Total Investment: 6,000,030,000 yuan
Overview of the Proposed Project: Using refined phosphoric acid, monoammonium phosphate (purchased externally), pure iron, ferrous sulfate, hydrogen peroxide, etc. as main raw materials, a 500,000 tons/year ferrophosphate production line will be built using the iron-based process, while another 500,000 tons/year ferrophosphate production line will be constructed using the ammonium-based process; corresponding auxiliary facilities will also be installed. The main product is iron phosphate, while the by-products include ammonium sulfate, etc. The environmental protection measures mainly include: the reaction off-gases from the 500,000-tonne ferrophosphate production line are washed through two stages of water treatment before being discharged in compliance with regulations; the production line is equipped with a 40-metre-high exhaust stack ； After dust-containing exhaust gas is filtered using bag filters, it is discharged up to standard specifications through a 24-meter chimney ； Production wastewater is concentrated using steam; the concentrated liquid is returned to the system for iron dissolution reactions. After evaporation and condensation, most of it is used as washing water, while the remainder is reused as make-up water. In the 500,000-ton ferrophosphate production line produced by the ammonium method, the phosphate-dissolving exhaust gas is discharged after being treated through spraying and absorption to meet the required standards; the sintering exhaust gas is also discharged at a height of 28 meters after being treated via incinerators and spraying/absorption to meet the specified standards ； The exhaust gas from material feeding and packaging is treated by a bag filter before being discharged through a 28m high exhaust stack ； The production wastewater is treated at the wastewater treatment plant through two stages of neutralization with lime and two stages of sedimentation, after which it is reused or discharged once it meets the required standards. Domestic waste is collected and disposed of uniformly by the sanitation department ； Hazardous waste generated by the project, such as mechanical maintenance waste and spent catalysts, is collected and temporarily stored in the plant’s hazardous waste storage area, before being regularly handed over to qualified entities for centralized disposal. Low-noise equipment should be used, along with sound insulation and vibration damping measures, to ensure that noise levels at the factory perimeter as well as the ecological environment quality of sensitive areas remain within acceptable standards.
