Embodiment 1

[0016]Example 1: Use plastic buckets to collect the sludge produced by the slaughter sewage treatment plant (that is, the sludge produced after the slaughter sewage is treated by the slaughter sewage treatment plant, for each embodiment, the same below), add an appropriate amount of auxiliary materials and stir to make the big head gold Fly maggot feed, the formula of feed is shown in Table 1 (the sum of the mass percentages of each component is 100%). The bran powder used is rice bran powder, and of course one or more mixtures of rice bran powder, rice bran powder, wheat bran powder, etc. Pour the feeding material into the corresponding box, the feeding material is 8cm thick, and put in an appropriate amount of golden fly eggs (that is, insert an appropriate amount of golden fly eggs on the surface of the feeding material), and the egg density is: 1g of golden fly Eggs / 1kg feed, hatched into golden fly larvae at 30°C after picking up the eggs. The eggs of Chrysocephalus chin...

Embodiment 2

[0023] [0023] Embodiment 2: Collect the sludge that slaughtering sewage treatment plant produces with plastic barrel, add appropriate amount of auxiliary materials and stir to make Chrysophyllum macrocephala feedstuff, the formula of feedstuff is as shown in Table 2 (used bran powder is rice bran powder, of course One or more mixtures of rice bran powder, rice bran powder, wheat bran powder and other bran powders can also be used, and the proportioning ratio of several kinds of mixtures is arbitrary). Pour the feeding material into the corresponding box, the feeding material is 13cm thick, and put in an appropriate amount of golden fly eggs, the egg density is: 2.5g of golden fly eggs / 1kg feeding material, hatch at 43°C after the eggs are picked into Chrysocephala larvae. The eggs of Chrysocephalus chinensis hatched into larvae on the second day and began to eat feed. On the 4th day, put a bigger box outside the feeder box again, and sprinkle dry bran powder therein to faci...

Embodiment 3

[0030] Embodiment 3: collect the sludge that slaughtering sewage treatment plant produces with plastic barrel, add appropriate amount of auxiliary material and stir and make golden fly maggot feedstuff, the formula of feedstuff is as shown in table 3 (used bran powder is wheat bran powder or Rice bran powder or a mixture of wheat bran powder and rice bran powder, the mixing ratio is arbitrary). Pour the feeding material into the corresponding box, the feeding material is 10cm thick, and put in an appropriate amount of golden fly eggs. The density of the eggs is: 3g of golden fly eggs / 1kg feeding material. After the eggs are picked, they are hatched at 50°C. Chrysanthemum fly larvae. The eggs of Chrysocephalus chinensis hatched into larvae on the second day and began to eat feed. On the 4th day, put a bigger box outside the feeder box again, and sprinkle dry bran powder therein to facilitate the collection of golden fly maggots. After 4 to 5 days, the larvae of Chrysocephala ...

Abstract

The invention relates to a method for treating sludge produced by a slaughtering wastewater treatment plant by using chrysomyia megacephala maggots and a material formula. According to the method, adjuvants are added to the sludge and are stirred so as to prepare a chrysomyia megacephala maggot feeding material, chrysomyia megacephala eggs are put into the chrysomyia megacephala maggot feeding material, and larvae incubated from the chrysomyia megacephala eggs eat the chrysomyia megacephala maggot feeding material, so that the sludge is treated. The mass fraction of the sludge in the chrysomyia megacephala maggot feeding material is 45-95%, the rest is the adjuvants, and the adjuvants consist of the following substances in percentage by weight: 0-30% of cattle manure, 0-40% of bagasse, 0-10% of rapeseed meal, 0-40% of peanut shell, 0-30% of corncob, 0-30% of beer dregs, 0-30% of bran powder, 0-5% of potassium dihydrogen phosphate and 0-5% of sodium dihydrogen phosphate. The method and the material formula have the advantages that the treating capacity is strong, the treating speed is higher than that of ordinary composting, and the treatment cycle is 4-5 days. After treatment, the volume of the sludge is decreased by 10-30%, odors are reduced, and meanwhile, a high-quality organic fertilizer and high-quality insect biological protein can be obtained.

Description

technical field [0001] The invention relates to a sludge treatment method, in particular to a method for treating sludge produced by a slaughter sewage treatment plant by using botany maggots, and belongs to the field of environmental protection. The invention also relates to a material formulation for carrying out the above method. Background technique [0002] Slaughter wastewater comes from pen washing, rinsing, slaughter and other workshop floor washing, scalding, dissection, non-staple food processing, oil washing, etc. It is one of the largest sources of organic pollution in my country. According to the survey, the discharge of slaughter wastewater accounts for about 6% of the national industrial wastewater discharge. During the treatment of slaughter wastewater, a large amount of excess sludge will be produced. The protein content in the excess sludge is too high, it is not easy to dehydrate, it is oily and sticky, and it is difficult to treat. Therefore, how to rea...
