Device.
Background technology
Existing traditional solid-liquid separation technique, mud-water separation is realized mainly by gravitational settling, but separation is not thorough, and
The tiny and colloidal solid in waste water is become big and then set by settling vessel etc. by substantial amounts of coagulation and flocculation medicament
It is standby to complete separation of solid and liquid using a longer hydraulic detention time.
Prior art shortcoming：
1st, pre-treatment reaction facility is more, floor space is big.
2nd, dosing species is more, and chemical feeding quantity is big, and operating cost is high.
3rd, cause water outlet viscosity big due to adding polyacrylamide, be not suitable for reuse.
4th, sludge yield is big, causes sludge treatment costly.
5th, separation of solid and liquid is not thorough, causes subsequently to need to add other filter plants, to improve treatment effect, to cause whole
Individual handling process length.
The content of the invention
The utility model is added by less medicament, relatively little of sludge quantity is produced, without using polyacrylamide
Deng flocculation medicament under the premise of, separated in time into high efficient solid and liquid separation membranous system, implementation process is short, occupation of land is small, efficiency high,
The purpose of stable water outlet.
The utility model is achieved through the following technical solutions：
A kind of high efficient solid and liquid separation membranous system device, including thickener, sour rinse bath, secondary sodium rinse bath, membranous system support,
Switch board, high efficient solid and liquid separation membranous system, feed pump, sludge pump, cleaning pump and blast pipe, thickener is by feed pump and efficiently
Separation of solid and liquid membranous system is connected, and sour rinse bath and time sodium rinse bath are connected by pipeline with high efficient solid and liquid separation membranous system, and it is special
Sign is：Described thickener accepts the mud waste water containing solid particle after pre-treatment dosing, and waste water is entered high by feed pump
Separation of solid and liquid membranous system is imitated, solid-liquid separation membrane separates to carrying out separation of solid and liquid containing mud waste water through high efficient solid and liquid separation membranous system
Water discharged by producing the mouth of a river, sour rinse bath and time sodium rinse bath are connected to the disengaging of high efficient solid and liquid separation membranous system by pipeline
Mouthful, the concentrated water of high efficient solid and liquid separation membranous system outlet is back to thickener by pipeline；Above-mentioned technical proposal is made further
Illustrate, described high efficient solid and liquid separation membranous system is internal pressure tubular cross flow formula high efficient solid and liquid separation film；It is provided with the thickener
Liquid level sensor, liquid level sensor control feed pump automatically turn on；Above-mentioned technical proposal is further described, described is dense
Contracting trench bottom is provided with sludge pump, when sludge condensation is to 20000-30000ppm, starts the quantitative spoil disposal of sludge pump.
The present utility model has the advantages that compared with prior art：
1st, thoroughly separation of solid and liquid is carried out, effluent quality is more preferable, turbidity<1,SS<3ppm.
2nd, it is not re-introduced into the pollution factor high polymer coagulant polyacrylamide for blocking various types of films, it is possible to achieve requirements at the higher level
Discharge or reuse.
3rd, occupation of land is compact, and area is small, saves space.
4th, dosing species and dosage are reduced, reduces operating cost.

Thickener accepts the mud waste water containing solid particle after pre-treatment dosing, and when reaching high level, feed pump can be automatic
Startup optimization, particle waste water containing mud is pumped into high efficient solid and liquid separation membranous system and separated, clean production water is flowed into back segment
System reuse or discharge, the concentrated water containing mud, which continues to be back to thickener, further to be concentrated.When sludge condensation to 20000-
During 30000ppm, start the quantitative spoil disposal of sludge pump, maintain the sludge concentration into membranous system balanced.Membranous system operation a period of time
Afterwards, permeant flux can decay, and Chemical cleaning is just carried out when reaching the aquifer yield of setting.Can be according to the contaminated situation of film
Analyze and select to carry out sour Chemical cleaning or time Sodium chemistry cleaning.General acid selection sulfuric acid or hydrochloric acid, concentration 2-4%, main solution
The certainly particulate pollutant such as metal ion and hardness.Secondary na concn is 2-3%, mainly solves organic pollution.Chemical cleaning can adopt
With wash cycles, soaking and washing can also be used, scavenging period is generally 2-8 hours.
