[0002] In the process of using bioleaching technology to treat sludge, it is necessary to add chemicals to sewage or sludge to improve the dewatering performance of sludge. The addition method and dissolution state of the chemicals are closely related to the process operation effect. Due to the large size of the dissolution device, it is usually necessary to add chemicals from the top of the dissolution device. If the addition is improper, it is easy to splash, affecting the on-site environment and the safety of operators, and reducing the treatment efficiency. In addition, due to the large amount of chemicals used, if the dissolution is not sufficient, it is easy to block the pipe mouth, affecting the operation effect of the process.
