Vacuum filter sieve for treating sewage

Technical Field

The utility model relates to a sewage treatment technical field that the environmental protection is relevant, concretely relates to vacuum filter sieve of processing sewage.

Background

The existing feces treatment modes are divided into the following modes:

(I), USBR anaerobic tower + sewage treatment plant

The water from the treatment mode can be used as farmland irrigation water, the treated fermentation product can be used as organic fertilizer, the daily treatment capacity is high, the sewage can reach the three-level discharge standard, and the manure can be used as agricultural fertilizer. But it has many defects, 1, the investment is huge, and the investment of conventional capital construction is tens of millions. 2. Large occupied area and high requirement on the field. 3. The operation cost is high, and the main cost comprises medicines, electric power, manpower and the like. 4. The requirement on managers is high, and professional environment-friendly personnel are needed. 5. Is only suitable for enterprises with more than thirty thousand culture scales. 6. The input is not in direct proportion to the output, the organic fertilizer produced by the method is not matched with the manufacturing cost, most facilities can only deal with inspection, and no substantial treatment effect exists.

(II) biogas power generation and sewage treatment plant

The water from the treatment mode can be used as farmland irrigation water, power generation and organic fertilizer. The actual application condition of the generator is influenced by the climate temperature and the like, and the gas production rate is insufficient in most of time, so that the generator cannot run and cannot achieve the expected effect. The operation cost is too high, and the investment becomes a decoration. But it has many defects, 1, the investment is huge, and the investment of conventional capital construction is tens of millions. 2. Large occupied area and high requirement on the field. 3. The operation cost is high, and the main cost comprises medicines, electric power, manpower and the like. 4. The requirement on managers is high, and professional environment-friendly personnel are needed. 5. Is only suitable for enterprises with more than thirty thousand culture scales. 6. Input is not directly proportional to output.

(III) aerobic composting

The water that this processing mode came out can be done farmland irrigation water and be used as the fertilizer, and its practical application condition is that need pack in a large number, and it is difficult to find to pack, and it is with high costs to lead to fertilizer manufacturing cost height, and its output is not directly proportional with the input, invests in too big, and middle-size and small-size plant is unacceptable. But it has many defects, 1, the investment is huge, and the investment of conventional capital construction is tens of millions. 2. Large occupied area and high requirement on the field. 3. The operation cost is high, and the main cost comprises medicines, electric power, manpower and the like. 4. Input is not directly proportional to output. 5. The sewage is easy to be saturated and leaked, which causes the pollution of the surrounding environment.

In addition, the infiltration of the excrement and the sewage can not be effectively treated to cause the pollution of the drinking water at the periphery, thereby causing the pollution to the drinking water in rural areas. And environmental pollution causes the prevalence of mosquitoes around, which brings trouble to the life of residents.

Through deep research in the aquaculture industry, experiments show that the culture manure is high in concentration, the water content of the manure is 81%, the organic matter is 15%, the nitrogen is 0.6%, the phosphorus is 0.4%, the potassium is 0.44%, and the culture manure has the characteristics of non-degradable antibiotics, strong corrosivity, difficulty in reduction and the like.
