Embodiment 1
[0044] This embodiment provides a sewage treatment equipment, which can preferably pretreat sewage, and can preferably separate solid-phase pollutants of various particle sizes in sewage through graded filtration.
[0045] A kind of sewage treatment equipment of this embodiment comprises equipment body 100, and equipment body 100 comprises filter mechanism body 120, sedimentation device main body 110 and drainage device body 130 connected in sequence, and sewage can enter sedimentation device main body 110 from filter mechanism body 120 , and finally discharged through the drain body 130. Among them, the filter mechanism body 120 can remove large solid pollutants in the sewage, the sedimentation device main body 110 can remove small particle size solid phase precipitation pollutants in the sewage, and the drainage device body 130 can remove solid pollutants that cannot be settled in the sewage , while the drainage device body 130 can perform further filtering.

The invention relates to the technical field of sewage treatment, in particular to a water inlet filter mechanism used in sewage pretreatment. The filter mechanism body includes a filter mechanism housing, and a water inlet filter grille is arranged inside the filter mechanism housing. The water inlet filter grille includes a first protective frame on the side of the raw water inlet and a second protective frame on the side of the sewage inlet. A water inlet filter screen is arranged between the first protective frame and the second protective frame; the second protective frame includes a second protective frame bracket frame, and a backwash main pipe is arranged in the second protective frame bracket along the front and rear direction, and the backwash main pipe is provided with There is a backwash main channel; there are multiple backwash branch pipes between the backwash main pipe and the second protective frame support frame, and there are backwash branch channels connected to the backwash main channel in the backwash branch pipe; there are multiple backwash branch pipes at intervals. There are two backwash holes facing the water inlet filter, and the backwash holes are connected with the backwash branch channel. The invention can preferably take out large pieces of pollutants during sewage.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a water inlet filter mechanism used in sewage pretreatment. Background technique [0002] 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. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage produced in daily life, which refers to a complex mixture of various forms of inorganic and organic substances, including: ①floating and suspended solid particles of large and small sizes; ②glue Shape and gel-like diffuser; ③ pure solution. ...
