Problems solved by technology

Its shortcoming is: the time of anaerobic fermentation is long, it is difficult to control
Its disadvantages are: simple flocculation and sedimentation are expensive and prone to secondary pollution
Its disadvantages are: long processing time and large floor space
Its shortcoming is: because the large-scale application example of this craft is still relatively few, need to further improve
[0012] Under the current technical conditions, the increase of equipment construction cost and operating cost for treating lake sewage will become inevitable. The existing traditional process and treatment method have the disadvantages of long process flow, complicated control, large land occupation and high treatment cost.

Abstract

The invention discloses equipment and a removal method for treating sewage on regional lake surfaces by the aid of adsorbing and heating composite processes. The equipment comprises a sewage pool, a first water inlet device, a primary treatment pool, a backwash water collecting tank, a backwash water outlet pipe, a second water inlet device, a secondary treatment pool, a stirring and adsorbing device, a clear water drain pipe, a clear water pool, a backwash device, a control system and a motor boat. The removal method includes feeding raw water into the primary treatment pool via the first water inlet device; feeding primarily filtered sewage into the second treatment pool via the second water inlet device; starting the stirring and adsorbing device to realize adsorbing effects on particles in the sewage; draining secondarily treated clear water into the clear water pool; starting the backwash device to carry out backwash on the other devices after the other devices run for 10-20 hours; collecting backwash water by the backwash water collecting tank and draining the backwash water by the backwash water outlet pipe. The equipment and the removal method have the advantages that the equipment for treating the sewage on the regional lake surfaces by the aid of the absorbing and heating composite processes is high in purification rate, obvious oil dirt and particle absorbing effects can be realized, and the equipment and the removal method are broad in application range.

Description

technical field [0001] The invention belongs to the field of sewage purification devices, and in particular relates to equipment for treating regional lake surface sewage by an adsorption and heating compound method and a removal method thereof. Background technique [0002] With economic development and social progress, people's living water level is increasing day by day. Coupled with the acceleration of urbanization, more and more domestic sewage is produced in people's production and life. Domestic sewage contains a large amount of organic matter and nutrients such as nitrogen and phosphorus. If a large amount of domestic sewage is directly discharged into rivers and lakes without treatment, it will definitely cause pollution to the same degree in rivers and lakes. In severe cases, it may cause eutrophication of rivers and lakes, and the outbreak of cyanobacteria blooms. The outbreak of cyanobacteria blooms will cause water pollution. Excessive algae toxin content can al...
