An Example of Sewage Pipe Network Renovation Project in a Chemical Industry Park in Liaoning Province
In a park in Liaoning province,gravity flow is used to drain sewage.The investment and operation cost of this method is low,but due to land settlement and other reasons,some pipelines are damaged,which is not conducive to environmental protection.Moreover,due to some enterprises'illegal discharge and excessive discharge,the biochemical treatment system of the sewage treatment plant is disabled,and the operation cannot be stable for a long time,and the effluent quality is not up to the standard.In order to strengthen environmental supervision and clarify corporate responsibility,the management model of"one enterprise and one pipe"and intermediate monitoring station was proposed on the basis of the underground sewage pipe network transformation to the ground.This model was explored and analyzed in practice.The results show that this model strengthens the main responsibility of pollution control of enterprises,improves the operation efficiency of sewage treatment plants,and improves the internal management level of the park.The paper provides reference for the transformation design of sewage pipe network in chemical industry parks.
