Abstract

A process for biologically treating garbage to obtain active ecological fertilizer and reclaiming it includes separating organic substance from inorganic materials, biological fermentation of organic substance, baking, adding P, K trace elements and mineral to obtain granular active ecological fertilizer, crushing the inorganic materials, sterilizing, mixing with cement, drying accelerator and pigments, and die pressing to obtain colour tiles or building blocks.

Description

Ecological active fertilizer prepared from garbage by biological treating and method of comprehensive utilization

Invention field: the present invention relates to a kind of ecological active fertilizer prepared from garbage by biological treating and method of comprehensive utilization.

Background technology: at present; municipal wastes collects many more heaps such as mountain year after year more; influenced environment protection, become society one harm greatly, how to have turned waste into wealth; rational exploitation and utilization; this be each state of the whole world all in the important topic of paying close attention to, nation-building in July in this year portion, environment general bureau, joint conference of Department of Science and Technology dispatch formulations＜garbage treatment and pollution prevention technique policy 〉, propose " minimizing; resource utilization, innoxious ", as seen the pollution that causes of municipal wastes is more and more serious.Influence national economy, become the major issue of current social development.

Summary of the invention: the objective of the invention is to invent a kind of ecological active fertilizer prepared from garbage by biological treating and method of comprehensive utilization according to the problems referred to above, it mainly is the fertilizer that utilizes in the municipal wastes: as ight soil, coal ash, animal residue and various useless living plant are as the nutrient base material of bacterial classification, add many bacterial classifications and carry out biological fermentation, remove thick matter, add needed trace element of plant and phosphorus again, mineral substance such as potassium, make the required various ecological active fertilizers of plant, to make the residue brick and tile behind the composting sieve simultaneously, inanimate matter waste materials such as ore, it is broken after deodoring and disinfecting is disinfected, again after the 100-200 screening, add cement, quick dry agent, pigment is made masonries such as pavior brick through the high pressure condensation, thereby reaches the purpose of the comprehensive utilization of turning waste into wealth.

The present invention realizes like this, it mainly is to adopt " dynamic sour floatingization of bacterium method ", with the organic waste in the municipal wastes is base-material, add multiple microorganism and quick rotting agent and add an amount of moisture content, utilize the quick stacking rot turn into fertilizer principle of high temperature, the various trace elements that the base manure baking (solarizations) after rotting of will fermenting then is dried to add phosphorus, potassium again and help plant-growth is made the particulate state ecological active fertilizer.Produce to sieve in the fertilizer and make the remaining brick and tile in back, organism sterilization degree after fragmentation such as pottery, sandstone become particulate state to add cement, quick dry agent pigment again through the high pressure condensation method, produce color paving tile and walling material.

(1) rubbish ecological active fertilizer compound method of the present invention is as follows:

1, compound method:

Between A, the garbage organism content 50-70%;

Between B, nitrogen, phosphorus, the potassium 15-25%:

Between C, the various trace elements 1-5%:

D, adding humic acids 4-5%;

E, adding mineral substance 10-15%;

The deodorizing bacterium of F, adding, withered grass bacterium, yeast, vinelandii, potassium solubilizing bacteria, big bacillus, milk-acid bacteria, actinomyces, water and multiple biological inoculum;

G, pH value are neutrality or slight alkalinity, and its pH value is between the 5-7, water content 10-20%.

2, production technique

The rubbish base-material is added into bacterial classification, deodorizing bacterium, withered grass bacterium, yeast, vinelandii, potassium solubilizing bacteria, big bacillus, milk-acid bacteria, actinomyces mix heaps fermentation, the turning sterilization, compost steams water again, sieves after Mechanical Crushing, the fragmentation then, and organism is separated with inorganics, the isolating organism in sieve back adds phosphorus, potassium and various trace elements, mineral substance, humic acids mixing again, test behind the extruder grain, the metering packing warehouse-in is made efficient organic ecological fertilizer then.

(2) sandstone, brick and tile, pottery are supported, are broken into 0.5 centimetre to 2 centimetres particulate state with ball mill down the inorganics behind the sub-sieve, scrap metal, resin glass to be extracted the recovery residue, add cement quick dry agent, pigment again, produce color paving tile and walling material through the high pressure condensation method.

Ecological active fertilizer prepared from garbage by biological treating of the present invention and method of comprehensive utilization, be that comprehensive utilization is turned waste into wealth, deodorizing is removed the evil, maintaining ecological balance, the ideal approach of beautifying the environment, it can effectively suppress or kill various rubbish and spread disease germs, alleviate diseases and pests of agronomic crop, it is nontoxic, harmless, pollution-free, and cost is low, the efficient height.

Claims (2)

1, a kind of ecological active fertilizer prepared from garbage by biological treating and method of comprehensive utilization, its feature is as follows:

(1) rubbish ecological active fertilizer compound method:

Between A, the garbage organism content 50-70%;

Between B, nitrogen, phosphorus, the potassium 15-25%;

Between C, the various trace elements 1-5%;

Between D, the adding humic acids 4-5%;

Between E, the adding mineral substance 10-15%;

F, the deodorizing bacterium that adds an amount of water and multiple biological bacteria, withered grass bacterium, yeast, vinelandii, potassium solubilizing bacteria, big bacillus, milk-acid bacteria, actinomyces;

It is neutral or alkaline that G, pH value are, and its pH value is between the 5-7, water content degree 10-20%

(2) production technique:

The rubbish base-material is added many bacterial classifications deodorizing bacterium, withered grass bacterium, yeast, vinelandii, potassium solubilizing bacteria, big bacillus, milk-acid bacteria, actinomyces, mixing heap fermentation, the turning sterilization, compost steams water again, Mechanical Crushing is sieved then, after sieving organism is separated with inorganics, and the organism after the separation adds phosphorus and various trace elements, mineral substance again, humic acids mixes, behind the extruder grain, test, the metering packing warehouse-in is made the ecological fertilizer of efficient organism then.

2, according to described a kind of ecological active fertilizer prepared from garbage by biological treating of claim and method of comprehensive utilization, it is characterized in that the inorganics scrap metal behind the sub-sieve, plastics, glass are extracted recovery, residue sandstone, brick and tile, pottery down is broken into 0.5 centimetre to 2 centimetres particulate state with ball mill, adds cement quick dry agent, pigment again and produces color paving tile and walling through the high pressure condensation method again.
