Sewage recovery device with multiple filtering functions

Abstract

The invention belongs to the technical field of environmental protection, and particularly relates to a sewage recovery device with multiple filtering functions. The sewage recovery device comprises acover body and a tank body, the cover body and the tank body are detachably connected through bolts, the side wall of the tank body is fixedly connected with multiple groups of water inlet pipes, andthe water inlet pipes are provided with a filter assembly in a matched manner. The filter assembly comprises a support, an outer filter screen and an inner filter screen, one end of the outer filterscreen is fixedly connected with the support, the support is slidably connected with the tank body, the other end of the outer filter screen is movably connected with the inner filter screen through atransmission mechanism, the inner filter screen is fixedly connected with a water outlet pipe, and the water outlet pipe is slidably connected with the cover body. By arranging the sewage recovery device with the multiple filtering functions, the multiple filtering effects are achieved in the sewage recovery treatment process, the sewage treatment time is shortened in cooperation with dosing, mixing and precipitation, the sewage recovery efficiency is improved, secondary utilization of sewage can be rapidly achieved, and the sewage treatment cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a sewage recycling device with multiple filtering functions. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or 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. In order to make full use of water resources and better protect the environment, people pay more and more attention to the recycling of sewage. However, there are still some deficiencies in the actual treatment process of common sewage recycling devices on the market that need to be improved urgently. [0003] In the existing technology, most of the recy...

In order to make full use of water resources and better protect the environment, people pay more and more attention to the recycling of sewage, but there are still some deficiencies in the actual treatment process of common sewage recycling devices on the market that need to be improved urgently

[0003] In the existing technology, most of the recycling of sewage needs to go through multiple links such as collection, sedimentation, and filtration. Existing sewage recycling devices often use separate treatment operations in the face of these steps. This treatment method is In the process of large amount of sewage treatment, there is inevitably the problem of long time-consuming sewage recycling, which cannot realize the rapid recovery and utilization of sewage, greatly reduces the efficiency of sewage recovery, and increases the treatment cost of sewage treatment process
