Problems solved by technology

[0002] During the construction on the construction site, dump trucks are used as the means of transportation. They mainly transport things that are not easy or not afraid of being broken. , not secondary recycling will cause serious waste of resources
[0003] In the sewage filtration system, a conventional membrane is usually used for filtration. When the conventional membrane is used, the suspended solids in the sewage will block the filter mesh. Therefore, it is necessary to add a backwash system to the entire system. As a backwashing system, it increases the cost, and the conventional membrane is very easy to clog during filtration, requiring frequent maintenance and replacement
[0004] The conventional filtration system needs to carry out a precipitation on the whole raw water when filtering, and the precipitation takes a lot of time, which increases the filtration time

Abstract

The invention discloses a construction dump truck washing wastewater filtration and circulation system and a filtration technology thereof. The system comprises a raw water tank, the water outlet end of the raw water tank is connected to a sand precipitation tank; and water is introduced into the raw water tank through a raw water inlet pipe, which is connected to a raw water pneumatic valve. The water outlet end of the sand precipitation tank is connected to a ceramic membrane filtration system, the water outlet end of the ceramic membrane filtration system is connected to an air floatation membrane filtration system, the water outlet of a concentrated water tank is connected to a press filter, which is provided with a water outlet and a mud outlet; the water outlet end of the water outlet is connected to the ceramic membrane filtration system, and the press-dried sludge from the mud outlet is applied to back filling or is transported out of the system. The wastewater generated by washing construction dump trucks is filtered by membranes. The whole equipment has a simple structure. The precipitation time of conventional technology is not needed. The filtered water can be directly used to wash construction dump trucks, after washing, the raw water can be filtered and recovered by the filtration system, no external water source is needed during the whole process, and thus the cost of vehicle washing is largely reduced.

Description

technical field [0001] The invention belongs to the cleaning field of construction dump trucks, and in particular relates to a filtration circulation system and a filtration process for construction dump truck washing waste water. Background technique [0002] During the construction on the construction site, dump trucks are used as the means of transportation. They mainly transport things that are not easy or not afraid of being broken. , not secondary recycling will cause serious waste of resources. [0003] In the sewage filtration system, a conventional membrane is usually used for filtration. When the conventional membrane is used, the suspended solids in the sewage will block the filter mesh. Therefore, it is necessary to add a backwash system to the entire system. It acts as a backwashing system, which increases the cost, and the conventional membrane is very easy to clog during filtration, requiring frequent maintenance and replacement. [0004] Conventional filtra...
