Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a two-stage magnetic separation type loading magnetic precipitation sewage treatment system, which solves the problem of high water content of sludge in the existing loading magnetic precipitation process, large amount of sludge and The problem of low magnetic recovery efficiency can complete wastewater treatment in large quantities, stably and quickly. The system is compact and occupies a small area. The sludge that has passed through the two-pole magnetic separation device can be directly filtered and transported out through the filter press without concentration.

Embodiment

[0024] Such as figure 1 As shown, a two-stage magnetic separation loading magnetic precipitation sewage treatment system includes a lifting device, a dosing device 2, a magnetic coagulation reaction device 1, a high-efficiency sedimentation tank 3, a two-stage magnetic separation device 4 and sludge treatment equipment 9 , a sewage pipeline is installed on the lifting device, the sewage outlet of the sewage pipeline is connected with the sewage inlet of the magnetic coagulation reaction device 1, and a dosing device 2 is arranged above the magnetic coagulation reaction device 1, and the magnetic coagulation reaction device 1 is used to form flocs from the pollutants in the sewage with magnetic powder as the core. The sewage outlet of the magnetic coagulation reaction device 1 flows into the high-efficiency sedimentation tank 3 through the pipeline. The bottom of the high-efficiency sedimentation tank 3 is equipped with a self-priming pump, such as figure 2 As shown, the two-s...

Abstract

The invention discloses a two-stage magnetic separation type loading magnetic precipitation sewage treatment system which comprises a lifting device, a chemical adding device, a magnetic coagulation reaction device, an efficient sedimentation tank, a two-stage magnetic separation device and a sludge treatment device. By comprehensive utilization of the two-stage magnetic separation device, the problems that an existing loading magnetic precipitation process is high water content in sludge, large in sludge quantity and low in magnetic recycling efficiency are solved, and wastewater treatment can be performed massively, stably and quickly; besides, the system is compact and small in occupied space, and sludge can be subjected to filter pressing and outward transport directly through a filter press without concentration.

Description

technical field [0001] The invention relates to the technical field of sewage magnetic separation, in particular to a two-stage magnetic separation type loading magnetic precipitation sewage treatment system. Background technique [0002] With the improvement of people's living standards and the abuse of social resources, the shortage of water resources is becoming more and more serious, and the increase in population will inevitably lead to more shortage of water resources. However, the development of social economy has polluted a large amount of social water resources, and the increasingly prominent social contradictions have led to the recycling and utilization of sewage resources. [0003] The existing sewage recycling industry develops relatively slowly. It usually adopts the traditional chemical precipitation method for treatment. The effect is not obvious, and the cost is high, which far exceeds the economic value brought by sewage recycling. Technology development f...
