Abstract
The invention relates to the harmless treatment of urban night soil, particularly about the invention of Physico-chemical catalystic, fermentative deodorizing method for nightsoil in city.The present invention at first carries out solid-liquid separation to ight soil, then removes tangible impurity, adds agent of materialization catalystic, fermentative deodorizing and additive then successively respectively, finally makes ight soil be converted into compoiste fertilizer.It is short that the present invention has the processing cycle, less investment (as build the factory that a day handles 100 tons of ight soil, its investment only be prior art about 1/5), do not have any environmental pollution, overcome the deficiency of prior art.Can be in each big and medium-sized cities widespread use.
Description
The invention relates to the harmless treatment of urban night soil, particularly about the invention of Physico-chemical catalystic, fermentative deodorizing method for nightsoil in city.
The innocuity treatment problem of urban night soil is subjected to the attention of countries in the world in recent years.The general treatment process of urban night soil is to add some chemical substance, its stink is eliminated, drain into the rivers sea then, the weak point of this method is first investment big (as build the factory that a day handles 100 tons of ight soil and need invest 3,000 ten thousand dollars or more), and it two is the latencies that still have contaminate environment.Innocuity treatment problem at each big and medium-sized cities ight soil of China is still unresolved, mainly is that the peasant of counties and districts directly applies the field near giving, and the time spent does not just directly enter sewer line, inflow rivers, contaminate environment as the peasant.Recently, the method that Shanxi province Taiyuan city environmental health protection office sets about studying with microbial fermentation is carried out harmless treatment to urban night soil, and each long processing period reaches 15-20 days.According to their estimation, build the factory that a day handles 100 tons of ight soil, take up an area of about 50000 square metres, will invest 5,000,000 RMB at least, but this method is not achieved success as yet at present.
Task of the present invention is that a kind of equipment of design is simple, the processing cycle is short, the method for the urban night soil harmless treatment of less investment.
The present invention can be by following scheme implementation.
Be that ight soil carries out solid-liquid separation at first, then remove tangible impurity (as stone, fragment of brick and plastics etc.) wherein respectively main raw material.
The processing of solid-state ight soil: in the solid-state ight soil of removing tangible impurity, add the materialization catalyzer, just can remove its stink, add additive then and make its curing.Again according to the production technique of present fertilizer enterprises and equipment to the curing of gained ight soil stir pulverizing, oven dry, granulation and packing, finally make solid-state ight soil be converted into solid-state compoiste fertilizer.
The processing of liquid ight soil: in the liquid ight soil of removing tangible impurity, add the materialization catalytic deodorizer, just can remove its stink, add additive then, stir, remove precipitation (this precipitation is transferred to and continues in the solid-state ight soil treatment process to use) after leaving standstill, resulting liquid is liquid organic composite foliage fertilizer, with its pack into transfer cask or hold-up vessel.
Deodorizing reaction in this urban night soil facture can be carried out at 2-5 minute fully; From main raw material is that the output of putting into compoiste fertilizer of ight soil only needs a few hours to get final product, and the processing cycle shortens greatly; Less investment, used various major equipments are China chemical fertilizers production enterprise general equipment at present, do not need specialized designs, if desire to build the factory that a day handles 100 tons of ight soil, take up an area of 7000 square metres of less thaies, production line 500,000 RMB of under-capitalizing.
The invention will be further described below in conjunction with Figure of description.
Accompanying drawing is the process flow diagram of Physico-chemical catalystic, fermentative deodorizing method for nightsoil in city.
Alleged " agent of materialization catalystic, fermentative deodorizing " in the accompanying drawing is to succeed in developing among the present invention, and its component more complicated is mainly the inorganic salt and the organic solvent of iron.The various reodorant of selling on its deodorizing principle and the market have very big difference.
Alleged " additive " in the accompanying drawing derives from the tankage (liquid) of the north suburb, Xi'an one chemical fertilizers production enterprise.It not only contains major element and trace elementses such as iron, zinc such as nitrogen, phosphorus, potassium, also contains some carbonate.Its effect has two: the first is solidified object being treated, is convenient to following processing; It two is to have increased use value (promptly having increased the effectiveness of composite fertilizer) for finished product.
Therefore the present invention has overcome the deficiency of prior art, realized the urban night soil harmless treatment less investment (as desiring to build the factory that a day handles 100 tons of ight soil, its investment only be prior art about 1/5th), the processing cycle lacks, turn bane into boon, without any environmental pollution.The scale of handling can be suited measures to local conditions, and the present invention can be in each big and medium-sized cities widespread use.
