Problems solved by technology

The ability to adapt to complex domestic waste is not strong, the operating cost is high, supervision is difficult, investment is large, furnace temperature requirements are high, and the slag fly ash after incineration has not been safely disposed of, etc.
[0006] 3. Garbage composting products have high cost, low fertilizer efficiency, and regional limitations
[0007] In summary, there are many disadvantages in the current treatment methods and devices of municipal solid waste.

Embodiment 1

[0033] A method for domestic waste water treatment, comprising the following steps:

[0034] A. The domestic waste enters the coarse crusher through the conveyor belt and is then stored in the storage hopper;

[0035] B. The quantitative feeder performs quantitative feeding according to the production output requirements and the capacity of the hydraulic classifier, and the maximum feeding amount cannot exceed 10% of the capacity of the hydraulic classifier each time to avoid affecting the crushing effect and damaging the machine;

[0036] C. The material stored in the storage hopper enters the hydraulic classification pulverizer through the quantitative feeder. The hydraulic classification pulverizer is fed with water by the water supply system at the same time and starts the water flow to drive the motor to make the domestic garbage suspend in the water body according to its own weight with the water flow, and control it. The direction of the water flow is opposite to the di...

Embodiment 2

[0045] In the described step F, the recyclable materials sorted by the water buoyancy separator are recycled, and the specific recycling scheme is as follows:

[0046] The floating material is removed by a water filter and then sent to the production workshop by a conveyor belt to be made into fuel rods or packaging supplies.

[0047] The material in the middle layer is filtered through a rolling water sieve and then sent to the production workshop by a conveyor belt to be made into fuel rods or directly sold for processing.

[0048] After the sinking material is extracted into the water filter screen, the sand and gravel particles and other materials are separated by the drum sieve and the magnetic separation device. Other materials are collected and processed uniformly.

Embodiment 3

[0050] In the described step G, the treatment scheme of the sewage is as follows:

[0051]The sludge after the sewage is settled in the sedimentation tank is pumped to the mud high pressure filter by a mud pump for extrusion. After extrusion, the water content of the mud is about 50%-55% of the mud block, and the mud block is sent to the organic The fertilizer production workshop adds an appropriate amount of bacteria and other organic materials according to the ingredients of the mud block, and then ferments and produces the finished organic fertilizer.

Abstract

The invention discloses a method for water treatment of household garbage. The household garbage is subjected to crushing, hydrolyzing, automatic water buoyancy sorting and other manners to be classified and decomposed, different kinds of garbage are recycled in a targeted manner, organic matter and soil obtained through decomposition are used as organic fertilizer raw materials, and meanwhile dirt water generated in the treatment process is subjected to innocent treatment. In the whole process, no manpower is needed, full-automatic sorting is achieved, energy consumption is low, and the resource utilization rate is high. The hazard caused by irrational utilization of the garbage to the environment is reduced more effectively, and a preferred embodiment for garbage resourceful treatment and sorting is achieved.

Description

technical field [0001] The invention relates to the technical field of garbage disposal, in particular to a method for treating domestic garbage water. Background technique [0002] With the development of the market economy, with the continuous improvement of people's living standards, the amount of domestic waste in the city is increasing year by year, and the growth rate is getting faster and faster. How to solve the problem of domestic waste, automatic sorting and recycling of domestic waste Utilization is a long-term solution to deal with domestic waste. [0003] At present, three major technologies are mainly used in the design and operation of domestic waste sorting and treatment in my country: landfill, composting, and incineration. These domestic waste treatment technologies will cause secondary pollution to the environment. [0004] 1. The landfill not only occupies a large amount of land, but also causes secondary pollution that causes serious harm to the social ...
