Embodiment 1

[0022] The main system of this comprehensive system is composed of urban waste classification system, farm waste system, factory waste waste liquid system that can be degraded by microorganisms, urban sewage system, plant production of clean energy, sewage "aerobic" treatment and other supporting subsystems; Only one subsystem can be selected to form a complete set with the main system. To make up for the insufficiency that the existing treatment technologies such as garbage and sewage cannot be fully centralized, large-scale, automatic and comprehensive treatment. At the same time, it can also save a lot of manpower and material resources, reduce processing costs, and generate certain economic benefits.

[0023] The present invention adopts "container" to load material into the biogas digester and ferment in the way of flowing water production line, which solves the problem of mixed new and old materials in the current fermentation tank, insufficient fermentation, stones and ...

Embodiment 2

[0036] The main process is the same as that of Embodiment 1, except that the hanging basket is cancelled, and the structure of a carrier vehicle is adopted, so that the structures of the pretreatment pond and biogas digester are different.

[0037] The pretreatment pool is a tunnel structure. The characteristics are: the "container" is placed on the carrier vehicle and pushed into the pool, adding quicklime into the pool, closing the front and rear doors, and passing in steam for pre-treatment. After the treatment, the car and the "container" are sent to the biogas digester together.

[0038] The biogas digester is a cuboid pool, and the pool is built underground, and it should be built deeper from the ground in cold regions. Biogas storage tanks or farms can be built above the biogas digester. Biogas digesters are suitable for small towns with a lot of land and not much disposal. Its characteristics are: the biogas digester is built with concrete or other materials, and th...

Embodiment 3

[0040] Implementation example 3: The biogas digester in this implementation is a newly built pond. After half a year of use, the top leaked, and the top cover was removed for reconstruction. Digester capacity 400m 3 , 3 engineering plastic pulleys are installed in the biogas digester, the feed inlet is discarded, and 1 pulley is installed at the discharge outlet, and a nylon rope is placed on the wheel, and many waste plastic barrels with an aperture of 3 are hung on the rope. Single barrel body set 0.6 cubic meters. By manually dragging the nylon rope, circular fermentation and discharge are realized. The operating temperature is normal temperature, the gas production of the biogas digester is 1 to 2 times higher than in the past, and there is still 1 to 2 times the gas production potential. Among them, there is a special box with a mouth size of 1.5 x 1.5 x 1.5 meters. After fermentation is run in the pool, the box is opened for inspection, and the fermentation effect is e...

Abstract

The invention relates to an automatic synthesis treatment system to produce biogas with garbage and sewage and plant, which comprises: loading the material into a container to send into the pretreatment pond for heating and adding quick lime; then, sending the container into a sealed biogas generating pit for fermentation; then, pouring out the material from container on the sludge separation pond for separation. The advantages of this invention include: full automatic or semi-automatic running; need little land; need not big repair for 20-30 years; reducing energy consumption and labor greatly; well economical benefit; and solving the health and safety problem for garbage go-no-go worker.

Description

Technical field [0001] The invention relates to an automatic comprehensive treatment system and method for producing biogas by utilizing garbage, sewage and plants, and belongs to the fields of environmental protection and green renewable energy. Background technique [0002] Municipal garbage, urban sewage, industrial easily decomposable organic wastewater, farm animal manure, and garbage need more effective, lower-cost, fully automated treatment methods that can create certain economic benefits. [0003] After the price increase of oil, the whole world is looking for new energy alternatives, using crop waste and artificially planting biogas-producing plants to produce biogas, using biogas to generate electricity intermittently, alleviating the shortage of power supply in urban peaks, is a way to produce green energy Very economical way; the energy it produces is far more cost-effective than producing ethanol with corn and sugar cane. [0004] There are many technologies f...
