Description
Technical field
The utility model relates to a kind of fermentation processing unit of urban wastewater treatment firm mud.
Background technology
According to " " 12 " national urban wastewater treatment and the planning of regeneration Facilities Construction ", by 2015, wastewater treatment in China scale will reach 2.08 billion cubic meters/day, and by this estimation, the annual dewatered sludge produced can reach about 1,100 ten thousand tons.In mud moisture 85%, the actual generation of the annual mud of China reaches 7,300 ten thousand tons.
Mud is the sedimentable matter that urban wastewater treatment firm produces in sewage treatment process, the extremely complicated heterogeneous body be made up of organic relic, microorganism, inorganic particle and colloid etc.Urban wastewater treatment firm mud not only water content is high, perishable, has strong odor, and is difficult to poisonous and harmful and the carcinogenic substance of degraded containing a large amount of pathogenic bacteria, parasitic ovum and the heavy metal such as chromium, mercury and Dioxins etc.The unprocessed random stacking of mud, through erosion and the seepage effect of rainwater, very easily causes secondary pollution to underground water, soil etc., and direct harm humans is healthy.The sharply increase of China's municipal sludge generation, is badly in need of harmless treatment and disposal of resources.
Heavy Metals in urban wastewater treatment firm mud and biological effectiveness directly have influence on the security of sludge landfill characteristics.We are in the research of sewage sludge harmlessness, recycling, use the achievement of solidification/stabilization technique and in-situ passivation recovery technique, HMF type heavy metals immobilization agent (fixative) of Yancheng City Baeyer logical sequence Environmental Protection Technology Co., Ltd research and development is added in mud, then through mixing, high-temperature aerobic fermentation.Mud is after aerobic fermentation process, pathogen reduction, organic humus, heavy metal are fixed, plant can utilize form nutrient to increase, the physical behavior, sanitation degree, solubleness, nutrient balance etc. of mud are all greatly improved, product nitrogen, phosphorus, potassium total nutrient, organic content has had raising.The shale obtained can be used for afforestation, forest land is built, and the soil improvement of saltings, desertify ground and discarded mining site, can produce fertilizer, mixed organic manure, slowly-releasing organic-inorganic compound mixed fertilizer etc.For solving urban wastewater treatment firm recycling sludge, safe utilizes the technical scheme providing a kind of practicality.
But the most industrial scale of existing fermentation unit is little, mechanize, level of automation are not high enough, add that mud is not only dirty but also smelly, substantial amounts, special need a kind of on environment without impact, the device that can carry out fermentative processing on a large scale.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of running cost low, does not produce environment and pollutes, also can ensure aerobic fermentation Effec-tive Function, the device of suitable for mass production when outside air temperature is low.
The technical solution adopted in the utility model is as follows:
A fermentation processing unit for urban wastewater treatment firm mud, includes the spiral conveyer of heavy metals immobilization agent scale tank, heat-conducting oil heating; Heavy metals immobilization agent is measured through scale tank, enters mixing machine after being heated to certain temperature by the spiral conveyer of heat-conducting oil heating, is fully uniformly mixed in mixing machine with a certain amount of mud, and mixture Transport Machinery heap is laid in sunlight fermentation vat; Sunlight fermentation vat bottom even is arranged with ventpipe, air is by being blown into bottom fermentation vat by gas blower after the air heat exchanger heating of heat-conducting oil heating, the mixture of heavy metals immobilization agent and mud is made to carry out aerobic fermentation, the tail gas that fermentation produces is emptying through washing pool, induced draft fan and deodorization chamber * winding paper by the vapor pipe being arranged on fermentation vat top with the water vapor driven out of, sunlight fermentation vat is provided with remote control turnover throwing machine, every day, the mud to fermentation was stirred, and guaranteed that mud fully ferments, slaking.
The fermentation processing unit of above-mentioned urban wastewater treatment firm mud, chuck is equipped with in the outside of described spiral conveyer, and the heavy metals immobilization agent of thermal oil to conveying that chuck can pump into heat is heated to required temperature.
The fermentation processing unit of above-mentioned urban wastewater treatment firm mud, the described thermal oil flowed out by spiral conveyer chuck again through air heat exchanger to the air heating being conveyed into fermentation vat to required temperature, guarantee the leavening temperature of the fermentation vat when outside air temperature is low; The heat conductive oil inlet of air heat exchanger is provided with valve, by-pass valve and pipeline, can regulate the thermal oil flow needed for interchanger, until close completely when not needing, makes thermal oil directly flow back to oil oven.
The fermentation processing unit of above-mentioned urban wastewater treatment firm mud, described deodorization chamber * winding paper is the brick or concrete sump of the biological material such as stalk, wood chip being filled with pulverizing, and gas enters from bottom, and top is discharged.After deodorizing effect reduces, the biological material more renewed, the biological materials such as the stalk of inefficacy, wood chip are mixed with mud carry out fermenting, maturation process.
Compared with prior art, the utility model has the advantage of: easy to operate, reliable, running cost is low; Suitable for mass production, can design equipment and the device of different size by industrial scale; Heating temperature can be regulated according to outside air temperature height, guarantee aerobic fermentation Effec-tive Function at relatively high temperatures; Ordorless smell discharge, not to environment.
