Working method of a multi-stage separation device for solid waste in sewage

Abstract

The invention relates to the field of sewage treatment, and concretely relates to a working method of a multi-stage separation device for solid waste in sewage. The device comprises the following components: a sewage pool, a filtering mechanism, a waste discharging mechanism, a suspended matter cleaning mechanism, a precipitant throwing mechanism and a solid separating mechanism; one side of the sewage pool is provided with an inclinedly arranged water inlet plate, and both ends of the water inlet plate are provided with baffles; the filtering mechanism is fixedly mounted at the upper ends ofthe two baffles, and the waste discharging mechanism is located at the side of the filtering structure; a partition is provided in the sewage pool, the partition partitions the sewage pool into a first treatment pool and a second treatment pool, wherein the partition is provided with a water inlet hole; and the suspension cleaning mechanism is fixedly arranged at an upper end of the first treatment pool, the sediment agent throwing mechanism is fixedly mounted at an upper end of the second treatment pool, and a solid separation mechanism is located at a side of the second treatment pool. The device has the beneficial effects that blocking condition of the filter net can be effectively prevented, and the solid waste in the sewage can be sufficiently separated by grading treatment.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a multistage separation device for solid waste in sewage. Background technique [0002] With the development of society, people's awareness of environmental protection is becoming stronger and stronger. In order to protect the environment from being damaged and improve people's living environment, sewage needs to be treated before it is discharged. The first step in sewage treatment is to treat sewage The solid waste contained in the sewage is filtered, but most of the existing sewage treatment devices are directly installed with a filter screen at the connection of the pipeline, and the solid waste is filtered out through the filter screen, but this filtering method is inconvenient for the filtered solid waste It is easy to cause the blockage of the filter screen, and the filtered solid waste will contain a lot of sewage, which is not convenient for the subsequent treatment of th...

[0002] With the development of society, people's awareness of environmental protection is becoming stronger and stronger. In order to protect the environment from being destroyed and improve people's living environment, sewage needs to be treated before it is discharged. The first step in sewage treatment is to treat sewage The solid waste contained in the sewage is filtered, but most of the existing sewage treatment devices are directly installed with a filter at the pipe connection, and the solid waste is filtered out through the filter, but this filtering method is inconvenient for the filtered solid waste It is easy to cause the blockage of the filter screen, and the filtered solid waste will contain a lot of sewage, which is not convenient for subsequent treatment of the filtered solid waste, and may even cause secondary pollution. This filtering method It is also impossible to filter out the fine waste floating on the sewage, and the suspended solids floating in the sewage also need to be assisted by flocculants to settle, so there are many deficiencies in the way of filtering through the filter
