The technical scheme adopted by the invention for solving the technical problems is as follows: a domestic sewage treatment process comprises the following steps:
a, arranging a grid pool to be communicated with domestic sewage to enable the domestic sewage to enter the grid pool to remove floating objects;
b, arranging a sewage adjusting tank behind the grating tank, so that water from the grating tank enters the sewage adjusting tank to adjust the water quality uniformly;
c, connecting a micro-electrolysis device at the outlet of a submersible pump in the sewage adjusting tank, enabling sewage in the micro-electrolysis device to overflow into the immersed ultrafiltration device, connecting a water production port of the immersed ultrafiltration device with a self-priming pump, and connecting the self-priming pump with a water production tank;
d, enabling the effluent of the sewage regulating tank to enter a micro-electrolysis device and stay for 0.1-1 h, enabling the micro-electrolysis device to use flexible activated carbon or silicon carbide as an electrode material, doping lithium or tin conductive materials in the electrode material, enhancing the conductivity of the electrode material, and enabling the effluent to pass through the electrode to be loaded by 5-30 mu g/cm2Ruthenium or iridium as a high-efficiency catalyst and an oxidant added into the device oxidize ammonia nitrogen in sewage into nitrogen, and insoluble iron phosphate is generated by generating iron ions and phosphate radicals to remove nitrogen, phosphorus and the like;
and E, enabling the sewage passing through the micro-electrolysis device to enter an immersed ultrafiltration device, removing generated suspended matters and bacteria in the domestic sewage, and obtaining effluent meeting the first-class A standard of urban sewage discharge.
Furthermore, a discharge port at the bottom of the immersed ultrafiltration device is connected with an inlet of the dehydrator through a sludge pump, mud cakes generated by the dehydrator are transported outwards, and filter pressing liquid returns to the immersed ultrafiltration device.
The main technical effects of the invention are explained as follows:
the treatment process of the domestic sewage of the invention, remove the large floater of the domestic sewage, regulate to homogeneous water quality, then enter the little electrolytic apparatus, through catalytic oxidation, degrade the organic matter in the sewage, remove nitrogen and phosphorus, and then through the immersed ultrafiltration apparatus, remove bacterium and suspended matter, etc. in the sewage, the final effluent accords with the urban sewage and discharges the first class A standard; the voltage required by the micro-electrolysis device is below 60V, so that the energy consumption is extremely low, the invention is specially designed for the domestic sewage discharge of 200t/d or below, and compared with the traditional treatment process, the invention has the advantages of low investment, small occupied area of equipment, low energy consumption, less sludge, simple operation and maintenance of the equipment and the like.
