Filter net of sewage purifying treatment system

Abstract

The invention discloses a filter net of a sewage purifying treatment system. An anti-corrosive metal coating is plated at the surface of the filter net, and comprises the following components in percentage by mass: 0.21 to 0.23% of C (carbon), 0.13 to 0.17% of Mg (magnesium), 0.62 to 0.65% of Cu (copper), 0.45 to 0.48% of W (tungsten), 0.55 to 0.58% of Ti (titanium), 5.32 to 5.35% of Cr (chromium), 0.37 to 0.39% of Ni (nickel), 0.42 to 0.45% of Mo (molybdenum), 0.23 to 0.25% of Co (cobalt), 3.42 to 3.45% of Ca (calcium), 11 to 13% of rare earth, and the balance of Fe (iron) and trace impurities, wherein the rare earth comprises the following components in percentage by weight: 5.2 to 5.5% of La (lanthanum), 7.6 to 7.8% of Ce (cerium), 5.2 to 5.6% of Pm (promethium), 5.5 to 5.8% of Nd (neodymium), 3.1 to 3.3% of Eu (europium), 5.5 to 5.8% of Sm (samarium), and the balance of Gd (gadolinium); chemical catalyst active components are attached into grid gaps of the filter net, and comprise the following components in percentage by weight: 5 to 60% of nanometer manganese dioxide, 1 to 3% of silver nitrate, 1 to 6% of lanthanum nitrate, and the balance of composite adsorbing material with micropore structure, the composite adsorbing material comprises the following components in percentage by weight: 30 to 50% of diatomite, 25 to 45% of sepiolite, 25 to 35% of molecular sieve, 5 to 10% of bentonite, and 1 to 10% of silica gel, and the sum of percentages of components is 100%.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment and purification equipment, in particular to a filter screen for a sewage purification treatment system. Background technique [0002] With the continuous development of the city, the city has become more and more crowded, and the noise pollution has become more and more serious. The bustling city center is no longer suitable for living. Therefore, some of the richer people choose to live in rural areas far away from the city center, which are quiet and have good air quality. Since the rural areas far away from the city center do not have systematic water supply and sewage discharge pipes, it is difficult to discharge water and sewage. [0003] At present, domestic sewage in rural residences is generally directly discharged into nearby small rivers, which not only causes pollution to the surrounding environment, but also wastes water resources; at present, there are various sewage treatme...

Problems solved by technology

Therefore, some of the richer people choose to live in rural areas far away from the city center, which are quiet and have better air quality. Since the rural areas far away from the city center do not have systematic water supply and sewage discharge pipes, it is difficult to discharge water and sewage.

[0003] At present, domestic sewage in rural residences is generally directly discharged into nearby small rivers, which not only causes pollution to the surrounding environment, but also wastes water resources; at present, there are various sewage treatment equipments on the market, but they treat The effect of sewage is not good, and it is impossible to control whether the sewage is treated up to the standard before it is discharged into the clean water tank, so that it cannot meet people's needs. This intelligent rural domestic sewage treatment system can effectively solve the above-mentioned problems to meet people's needs. usage requirements
