Garbage leachate treatment technology

Overview: the urban living garbage composition complex, affected by the factors such as economic development level, natural conditions, now the main processing way of composting, landfill and incineration, but whatever the process, the key, is the secondary pollutants, which has complex pollutant components, high concentrations of pollutants, heavy metal content is high.The company development of waste leachate treatment technology, dynamic mesh to biofilm equipment as core technology, better realize the covers an area of a province, the characteristics of low energy consumption, accomplish equipment specialized design, convenient construction or renovation, convenient operation management and health in good condition, and strong resistance to impact load capacity.

Pickling wastewater treatment technology

Pickling waste water has a large water quantity, water quality is not stable, strong corrosive, toxic and harmful characteristics, it will hinder the biological treatment of wastewater biological reproduction, affect crop growth and aquatic crops; The larger acidity of human and animal drinking water, which can cause an inflammation in the intestines and stomach, and even burn. And plenty of acid mist generated in the pickling process, not only damage the health of workers, and to plant, equipment corrosion, a large amount of acid mist evaporate at the same time, cause loss of acid liquid, increase the cost of pickling. Also contains a lot of heavy metal ions in acid pickling waste water by the water pollution caused by the excessive, the biological poison, and ultimately damage to human health is self-evident. To this end, the company developed a set of acid specifically for small and medium-sized enterprise technology solutions, using the company's development of inter...
