Embodiment Construction
[0015] like figure 1 As shown, a kind of waste water treatment equipment of the present invention, it comprises raw water tank 1, high-efficiency filter 2, bag filter 3, ultrafiltration system 4, security filter 5, reverse osmosis system 6 and reuse water pool 7 connected in sequence A dosing system 8 is set between the raw water pool 1 and the high efficiency filter 2, the ultrafiltration system 4 and the security filter 5. The raw water pool is used to store incoming water, regulate the water supply of the system, prevent the impact of insufficient water supply, and also play a certain role in the precipitation of impurities in the water supply. The original water pool is equipped with a backwashing device, which uses a low-lift, high-flow water pump combined with compressed air to perform backwashing, making backwashing more thorough. The high-efficiency filter uses a new type of fiber as the filter element, and the diameter of the filter material can reach tens of microns...

Abstract
The invention discloses a sewage treatment device and process method. The sewage treatment device is characterized in that the device comprises a raw water tank, a high-efficient filter, a bag type filter, a super filtration system, a security filter, a reverse osmosis system and a recycling water tank which are connected successively, wherein fiber is served as a filtration element of the high-efficient filter, and the bag type filter entraps and filtrates particles, the size of which is more than 50 mu m, leaked in the high-efficient filter; the super filtration system comprises a super filtration membrane group, a control instrument and meter, a water inlet valve and a flushing system, and impurity particles are removed in a physical entrapment way; a drug adding system is arranged between the security filter and the super filtration system, and the drug adding system is mainly formed by connecting a measuring tank, a measuring pump, and a pipeline; and the reverse osmosis system comprises a high pressure pump, a reverse osmosis membrane group, a cleaning system, a control meter and a pipeline system which are used for removing soluble salinity in water. The invention has the advantages that the problem of restrained enterprise water discharge can be resolved, total sewage drainage is reduced greatly, and the social benefits are obvious, thus the invention has good popularization value.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a waste water treatment equipment and process. Background technique [0002] Today, aluminum profile enterprises mainly produce process wastewater such as acid wastewater, alkaline wastewater, tin-containing and nickel-containing wastewater, chromium-containing wastewater, phosphorus-containing wastewater and a small amount of flushing wastewater in the production process. The main pollutants in wastewater are acid, COD, petroleum, aluminum, tin, nickel, chromium, phosphorus and other components. Judging from the current domestic popular technologies, the main wastewater treatment methods for aluminum profile enterprises in the production process generally adopt separate and simple integrated treatment equipment, and there are many combined processes, such as coagulation and sedimentation integrated treatment process. The principle is that after the wastewater is mixed ...
