A solid impurity sewage treatment device and method

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a solid impurity sewage treatment device and method. The problems that equipment needed in the conventional sewage treatment is great in quantity, the method is complicated and the energy consumption is high are solved. The solid impurity sewage treatment device comprises a base, a settling kettle, a sewage diversion pipe, a clean water outlet pipe and a sludge outlet. The equipment structure is simple, the clean water and sewage pipeline is clear, and sewage treatment can be completed by one piece ofequipment only. According to the solid impurity sewage treatment method, the solid impurity sewage treatment device is utilized, the sludge layer settled at the bottom of the settling kettle serves as a filtering medium of the sewage, the sewage settling speed and clean water outflow speed in the settling kettle are controlled to reach a balance by regulating the sewage injection speed, only onepiece of equipment is needed in the sewage treatment process, any chemical substance does not need to be added, and the method is green, energy-saving and environmental-friendly. The solid impurity sewage treatment device and method can be applied to treatment of sewage containing insoluble solid impurities.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a solid impurity sewage treatment device and a solid impurity sewage treatment method. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet water discharge standards or water quality requirements for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] Sewage treatment can be divided into three types according to its function: physical method, biological method and chemical method. (1) Physical method: It mainly uses physical action to separate insoluble substances in sewage, and does not change the chemical properties during the treatment process. Commonly used are gravity separat...
