Description

Sludge compost apparatus for producing

Technical Field

The application relates to the technical field of organic fertilizers, in particular to a sludge composting production device.

Background

With the construction and development of rural economy, the number of agricultural products is continuously increased and the large-scale development of livestock breeding industry is realized, the generation amount of rural organic wastes mainly comprising crop straws, livestock manure, residual activated sludge and the like is in a rapid rising trend, particularly, with the gradual extension of sewage treatment facilities and services to villages and towns, more and more residual activated sludge organic wastes are generated in the sewage treatment process, sludge treatment and disposal in rural sewage treatment are realized, residual sludge treatment and disposal units are basically absent, and with the long-term operation of the rural sewage treatment facilities, the problem of the residual activated sludge in the rural areas is more and more prominent.

The characteristics of the sewage quality of villages and towns are different from those of cities, the discharge area of domestic sewage of the villages and the towns is large and wide in dispersion, and the N, P content in water is high, so that the content of organic matters in residual sludge is high, the content of the organic matters is generally 30-60 wt%, the content of nitrogen is 2-6 wt%, the content of phosphorus is 1-4 wt%, the nutrient content is high, the content of heavy metals is low, the agricultural utilization potential is very large, and the rural area has great resource utilization potential. And for the scattered sludge discharge of villages and small towns, the sludge yield is not fixed, the transportation and treatment cost is higher, and the rural waste has no fixed storage point and no special treatment place due to the influence of economic conditions and traditional habits, so that the residual sludge generated after sewage treatment by a sewage plant is largely discarded, and part of the residual sludge is wrongly reused by farmlands. Not only pollutes the environment, but also threatens the physical health of rural residents all the time. Therefore, aiming at the characteristic of high organic matter of the surplus activated sludge in villages and towns, the composting agriculture is carried out on the surplus activated sludge, and the research and development of the sludge treatment technology which has practical value and is easy to operate are not slow.

The current domestic sludge treatment method is five main centralized treatment modes such as aerobic composting, anaerobic fermentation, drying incineration, landfill and the like, wherein the landfill method is the most used treatment mode in China. According to the regulation of GB16889-2008 pollution control standard of domestic garbage landfill, the domestic sludge can be landfilled for disposal when the water content of the domestic sludge is degraded to less than 60 wt%. However, with the emergence of the national future development requirements for resource utilization of waste and development of recycling economy, domestic sludge is brought into hazardous waste for supervision; with the emergence of higher and higher environmental protection current policy requirements and the emergence of high commercial requirements on land cost and transportation cost, the sludge landfill mode is replaced by other harmless and resource utilization modes.

At present, the following problems exist in the treatment of domestic sludge:

1. the cycle length is as follows: (1) the treatment period of 20-60 days cannot meet the requirement of sludge yield on treatment efficiency; (2) the long treatment period means large floor space and high land cost; (3) the unit processing cost of labor, energy consumption and the like is high;

2. secondary pollution: (1) the odor generated in the treatment process has great influence on the surrounding environment; (2) wastewater generated in the treatment process needs to be treated again; (3) the fertilizer and the biogas residue and the biogas slurry produced after the aerobic composting and the anaerobic fermentation can not meet the fertilizer requirement and need to be reprocessed, which can only account for secondary pollution.

3. Centralized processing: (1) increase in transportation costs (the second-line city, where land costs are high, is particularly prominent); (2) increasing the cost of transportation and loading and unloading.

4. The practical problems are as follows: (1) in the sludge-fertilizing project, the produced fertilizer cannot meet the quality requirement, and illegal transfer or landfill becomes a common phenomenon in the domestic sludge-fertilizing project; (2) the fuel gas production value of the sludge biogas project is low, the high operation cost of the biogas residues and biogas slurry of secondary treatment is high, and the operation stop ratio of the project is the same.

The aerobic composting technology has the defects of long treatment period, large occupied area, great influence of an open treatment process on the surrounding environment, and difficulty in meeting the quality requirements of organic fertilizers on the aspects of heavy metal, harmful bacteria, maturity and the like. Therefore, the waste water is still pollutant after being treated, and has to be transported, burned or even landfilled.

For the anaerobic fermentation technology, the treatment period is long (15-25 days or more), the occupied area is large, the dust production and the stored combustible gas have large safety problems, the biogas residues and the biogas slurry can be utilized after secondary treatment, the external temperature has large influence on the quality and the yield of the biogas, and the problem that the technology is limited to the maximum is that the investment cost is large, the economic benefit is very limited, and the investment recovery period can exceed ten years or more.

The sludge is high in moisture and low in calorific value by virtue of a drying incineration technology. Therefore, the method is only harmless treatment, and is not a method for resource utilization and highest treatment cost.

The landfill mode, the waste water that extrudes also need to be handled (need to degrade moisture to 60 wt% just can bury), pollute groundwater source, soil, peripheral resident environment, will be eliminated at last.

Aiming at the characteristics of the surplus activated sludge in villages and towns and the problems of the existing sludge composting technology, the treatment technology which can be developed in the future is creatively provided, and a rapid, efficient, simple to operate and sustainable sludge composting treatment method is developed, so that the problem that the sludge is converted into waste is urgently needed to be solved at present.

When the first sludge compost production device runs to the sixth day, the auxiliary material and the bacterial liquid are added into the second sludge compost production device at the same time, the enrichment culture of the strains is carried out, after the first sludge compost production device finishes the whole process running for seven days and removes all fertilizers, namely, the second sludge compost production device starts a new cycle in the second day, and so on, the two systems start to start the second set of systems when the previous system runs to the sixth day, thus completely ensuring the continuous running of the whole device.

The operation process of the single system is described by taking a first sludge compost production device as an example:

the first day: auxiliary material and bacterial liquid

(1) Treatment and delivery of adjuvants

Local waste straws, sawdust and the like of villages and small towns are collected on the spot to serve as auxiliary materials, the straws and the like enter a first auxiliary material container 3-1 through an auxiliary material inlet of the first auxiliary material container 3-1, the straws are crushed into auxiliary materials with particle sizes below 1cm by a first crushing cutter head 4-1, the first auxiliary material container 3-1 is provided with an auxiliary material outlet 6-1 which is connected with an auxiliary material inlet of the first sludge container 1-1, and the auxiliary materials are mixed with sludge through the auxiliary material outlet 6-1 according to a mass ratio of 1: 1 into a first sludge container 1-1.

(2) Culture and release of strains

The method comprises the steps of putting a compound microbial agent into a first bacterium liquid storage box 2-1 for storage, connecting a bacterium liquid outlet 9-1 of the first bacterium liquid storage box 2-1 with a bacterium liquid inlet of a first sludge container 1-1, putting the compound microbial agent (the mass ratio of the compound microbial agent to sludge in the first sludge container 1-1 is 1: 10) into the first sludge container 1-1 in the first day, starting a working mode of equipment after the bacterium liquid is put into the first sludge container 1-1 by taking auxiliary materials as carriers, starting a first stirring head 7-1 after the bacterium liquid is put into the first sludge container 1-1, controlling the rotating speed at 3r/min, continuously stirring, starting a first heating device 10-1, and controlling the heating temperature at 60 ℃. The bacteria liquid takes auxiliary materials as carriers, and crazy propagation is carried out under the optimal propagation temperature condition by taking stirring as external force. The number of the microbial strains propagated on the auxiliary materials after 24 hours is enough to decompose the sludge 6 days later.

Day two to day seven: bacterial liquid and sludge

(1) Sludge treatment process

In the first sludge container 1-1: after the added strains are proliferated on the auxiliary materials, continuously adding bacteria liquid (the mass of the bacteria liquid added every day accounts for 5 wt% of the total sludge treatment amount) and sludge (the mass of the sludge added every day accounts for one fifth of the total sludge mass) from the second day to the sixth day, fully mixing the sludge and the bacteria liquid through a first stirring head 7-1, continuously operating the first stirring head 7-1, and controlling the rotating speed at 3 r/min; the temperature is controlled at 60 ℃, the decomposition of the sludge is completed after 2h, the odor is changed into fertilizer fermentation odor from initial malodor, the ultra-fast fermentation and aging process is realized by fast disintegration and rupture of the molecular structure of the sludge, and the sludge in the sludge container is fermented by microorganisms after the first 12 h. The fermentation time is 12 h. And aging and sterilizing the fermented mixture in the rest 12h by using the sterilization function of the composite microbial inoculum.
